Earth is the only planet known to support life, and its natural features are the subject of many fields of scientific research. Within the solar system, it is third closest to the sun; it is the largest terrestrial planet and the fifth largest overall. Its most prominent climatic features are its two large polar regions, two relatively narrow temperate zones, and a wide equatorial tropical to subtropical region. Precipitation varies widely with location, from several metres of water per year to less than a millimetre. 71 percent of the Earth's surface is covered by salt-water oceans. The remainder consists of continents and islands, with most of the inhabited land in the Northern Hemisphere.Earth has evolved through geological and biological processes that have left traces of the original conditions. The outer surface is divided into several gradually migrating tectonic plates. The interior remains active, with a thick layer of plastic mantle and an iron-filled core that generates a magnetic field. This iron core is composed of a solid inner phase, and a fluid outer phase. Convective motion in the core generates electric currents through dynamo action, and these, in turn, generate the geomagnetic field.The atmospheric conditions have been significantly altered from the original conditions by the presence of life-forms, which create an ecological balance that stabilizes the surface conditions. Despite the wide regional variations in climate by latitude and other geographic factors, the long-term average global climate is quite stable during interglacial periods, and variations of a degree or two of average global temperature have historically had major effects on the ecological balance, and on the actual geography of the Earth.

Many common terms for seeds and fruit do not correspond to the botanical classifications. In culinary terminology, a fruit is usually any sweet-tasting plant part, especially a botanical fruit; a nut is any hard, oily, and shelled plant product; and a vegetable is any savory or less sweet plant product. However, in botany, a fruit is the ripened ovary or carpel that contains seeds, a nut is a type of fruit and not a seed, and a seed is a ripened ovule. Examples of culinary "vegetables" and nuts that are botanically fruit include corn, cucurbits (e.g., cucumber, pumpkin, and squash), eggplant, legumes (beans, peanuts, and peas), sweet pepper, and tomato. In addition, some spices, such as allspice and chili pepper, are fruits, botanically speaking. In contrast, rhubarb is often referred to as a fruit, because it is used to make sweet desserts such as pies, though only the petiole (leaf stalk) of the rhubarb plant is edible, and edible gymnosperm seeds are often given fruit names, e.g., ginkgo nuts and pine nuts. Botanically, a cereal grain, such as corn, rice, or wheat, is also a kind of fruit, termed a caryopsis. However, the fruit wall is very thin and is fused to the seed coat, so almost all of the edible grain is actually a seedA fruit results from maturation of one or more flowers, and the gynoecium of the flower(s) forms all or part of the fruit. Inside the ovary/ovaries are one or more ovules where the megagametophyte contains the egg cell. After double fertilization, these ovules will become seeds. The ovules are fertilized in a process that starts with pollination, which involves the movement of pollen from the stamens to the stigma of flowers. After pollination, a tube grows from the pollen through the stigma into the ovary to the ovule and two sperm are transferred from the pollen to the megagametophyte. Within the megagametophyte one of the two sperm unites with the egg, forming a zygote, and the second sperm enters the central cell forming the endosperm mother cell, which completes the double fertilization process. Later the zygote will give rise to the embryo of the seed, and the endosperm mother cell will give rise to endosperm, a nutritive tissue used by the embryo.

The Osage orange is commonly used as a tree row windbreak in prairie states, which gives it one of its colloquial names, "hedge apple". It was one of the primary trees used in President Franklin Delano Roosevelt's "Great Plains Shelterbelt" WPA project, which was launched in 1934 as an ambitious plan to modify weather and prevent soil erosion in the Great Plains states, and by 1942 resulted in the planting of 30,233 shelterbelts containing 220 million trees that stretched for 18,600 miles (29,900 km). The sharp-thorned trees were also planted as cattle-deterring hedges before the introduction of barbed wire and afterward became an important source of fence posts. In 2001, its wood was used in the construction in Chestertown, Maryland of the Schooner Sultana, a replica of HMS Sultana. The heavy, close-grained yellow-orange wood is dense and prized for tool handles, treenails, fence posts, and other applications requiring a strong dimensionally stable wood that withstands rot. Although its wood is commonly knotty and twisted, straight-grained Osage orange timber makes good bows, as once used by Native Americans. In Arkansas, in the early 19th century, a good Osage bow was worth a horse and a blanket. Additionally, a yellow-orange dye can be extracted from the wood, which can be used as a substitute for fustic and aniline dyes. At present, florists use the fruits of M. pomifera for decorative purposes. When dried, the wood has the highest BTU content of any commonly available North American wood, and burns long and hot. Unlike many woods, Osage orange wood is durable, making good durable fence posts. They are generally set up green because the dried wood is too hard to reliably accept the staples used to attach the fencing to the posts. Palmer and Fowler's Fieldbook of Natural History 2nd edition, rates Osage orange wood as being at least twice as hard and strong as white oak (Quercus alba). Although Osage oranges are commonly believed to repel insects, there is insufficient evidence to support this. Research has shown that compounds extracted from the fruit, when concentrated, may repel insects. However, the naturally occurring concentrations of these compounds in the fruit are far too low to make the fruit an effective insect repellent. In 2004, the EPA insisted that a website selling M. pomifera fruits online remove any mention of their supposed pesticidal properties as false advertisements.

until Christmas. Some have even said it goes back to the time of the Twelve Apostles or that it was founded by Saint Peter. This has led to the conclusion that it is "impossible to cl with confidence a credible explanation of the origin of Advent". Associated with Advent was a period of fasting, known also as the Nativity Fast or the Fast of December. Representation of Saint Perpetuus According to some sources, the ceration of Advent began in the fifth century when the Bishop Perpetuus directed that starting with the feast of St. Martin, 11 November, until Christmas, one fasts three times per week; this is why Advent is also named Lent of St. Martin. According to historians, this practice remained limited to the diocese of Tours until the sixth century. But the Macon council held in 581 adopted the practice in Tours and soon all France observed three days of fasting a week from the feast of Saint Martin until Christmas. The most devout worshipers in some countries exceeded the requirements adopted by the Council of Macon, and fasted every day of Advent. The homilies of Gregory the Great in the late sixth century showed four weeks to the liturgical season of Advent, but without the observance of a fast. However, under Charlemagne in the ninth century, writings cl that the fast was still widely observed. In the thirteenth century, the fast of Advent was not commonly practised although, according to Durand of Mende, fasting was still generally observed. As quoted in the bull of canonisation of St. Louis, the zeal with which he observed this fast was no longer a custom observed by Christians of great piety. It was then limited to the period from Saint Andrew until Christmas Day, since the solemnity of this apostle was more universal than that of St. Martin. When Pope Urban V ascended the papal seat in 1362, he simply forced people in his court to abstinence but there was no question of fasting. It was then customary in Rome to observe five weeks of Advent before Christmas. This is particularly discussed in the Sacramentary of St. Gregory. Ambrosiana or Milan Liturgies have six. The Greeks show no more real consistency; Advent was an optional fasting that some begin on 15 November, while others begin on 6 December or only a few days before Christmas. The Catholic Church, for centuries, has begun the season of Advent on the fourth Sunday before Christmas and neither fast nor abstinence are observed. No canonical penalty has ever been attached to the neglect of the practices of Advent. The Church has at times declined to administer the sacrament of matrimony during Advent, because of the joy connected with the ceration. The liturgy of Advent remained unchanged until the Second Vatican Council, in 19
the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely; they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the branches divide into smaller branches and shoots. The shoots typically bear leaves, which capture light energy and convert it into sugars by photosynthesis, providing the food for the tree's growth and development. Trees usually reproduce using seeds. Flowers and fruit may be present, but some trees, such as conifers, instead have pollen cones and seed cones. Palms, bananas, and bamboos also produce seeds, but tree ferns produce spores instead. Trees play a significant role in reducing erosion and moderating the climate. They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues. Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world. Trees provide shade and shelter

Some aqutic spec, such as sirens and ammas, have reduced or absent hind limbs, giving them an eel-like appearance, but in most species, the front and rear limbs are about the same length and project sidewards, barely raising the trunk off the ground. The feet are broad with short digits, usually four on the front feet and five on the rear. Salders do not have claws, and the shape of the foot varies according to the animal's habitat. Climbing species have elongated, square-tipped toes, while rock-dwellers have larger feet with short, blunt toes. The tree-climbing salamander (Bolossa sp.) has plate-like webbedfeet which adhere to smooth surfaces by suction, while the rock-climbing Hytes species from Carnia have feet with fleshy webs and short digits and use their tails as an extra limb. When ascending, the tail props up the rear of the body, while one hind foot moves forward and then swings to the other side to provide support as the other hind foot advances

A window is an opening in a wall, door, roof or vehicle that allows the passage of light, sound, and air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut or to hold it open by various amounts. Types include the eyebrow window, fixed windows, single-hung and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, thermal, or Diocletian, windows, picture windows, emergency exit windows, stained glass windows, French windows, panel windows, and double - and triple paned windows. The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt, in Alexandria ca. 100 AD. Paper windows were economical and widely used in ancient China, Korea and Japan. In England, glass became common in the windows of ordinary homes only in the early 17th century whereas windows made up of panes of flattened animal horn were used as early as the 14th century. In the 19th century American west, greased paper windows came to be used by itinerant groups. Modern-style floor-to-ceiling windows became possible only after the industrial plate glass making processes were fully perfected. The English language-word window originates from the Old Norse 'vindauga', from 'vindr – wind' and 'auga – eye', i.e., wind eye. In Norwegian Nynorsk and Icelandic the Old Norse form has survived to this day (in Icelandic only as a less used word for a type of small open "window", not strictly a synonym for gluggi, the Icelandic word for window), in Swedish the word vindöga remains as a term for a hole through the roof of a hut, and in the Danish language 'vindue' and Norwegian Bokmål 'vindu', the direct link to 'eye' is lost, just like for 'window'. The Danish (but not the Bokmål) word is pronounced fairly similarly to window. Window is first recorded in the early 13th century, and originally referred to an unglazed hole in a roof. Window replaced the Old English eagþyrl, which literally means 'eye-hole,' and 'eagduru' 'eye-door'. Many Germanic languages however adopted the Latin word 'fenestra' to describe a window with glass, such as standard Swedish 'fönster', or German 'Fenster'. The use of window in English is probably because of the Scandinavian influence on the English language by means of loanwords during the Viking Age. In English the word fenester was used as a parallel until the mid-18th century. Fenestration is still used to describe the arrangement of windows within a façade, as well as defenestration, meaning to throw something out of a window.
