The atmosphere of the earth
As the earth continued to cool, the water vapor found in the atmosphere condensed to form the oceans and other fresh water bodies on the continents. If you lived in aristotle's day you may have had strange beliefs about the atmosphere people back then knew it existed, but they didn't really know what it was it wasn't until centuries. Atmospheric processes interactions - atmosphere and ocean in the cycles overview, we learned that water is an essential part of the earth's system. The earth's atmosphere is an extremely thin sheet of air extending from the surface of the earth to the edge of space the earth is a sphere with a roughly 8000 mile diameter the thickness of the atmosphere is about 60 miles. The atmospheric composition focus area consists of research on the composition of earth's atmosphere, particularly of the troposphere and stratosphere, in relation to climate forcing, atmospheric ozone and aerosols, solar effects, air quality, and surface emissions of radiatively and chemically. The atmosphere of earth is the layer of gases, commonly known as air, that surrounds the planet earth and is retained by earth's gravity the atmosphere of earth protects life on earth by creating pressure allowing for liquid water to exist on the earth's surface.
Without the protective layer of gases that make up earth's atmosphere, the harsh conditions of the solar system would render the planet a barren, lifeless husk like the moon. Composition of earth's atmosphere as of dec 1987 the lower pie represents the least common gases that compose 0038% of the atmosphere values normalized for illustration. The evolution of earth's current atmosphere is not completely understood it is thought that the current atmosphere resulted from a gradual release of gases both from the planet's interior and from the metabolic activities of life-forms as opposed to the primordial atmosphere, which. Earth's atmosphere is the layer of gases around the earth the atmosphere is held in place by earth's gravity it is made up mainly of nitrogen (781%. A five-layer cake the atmosphere of the earth can be divided into five layers the bottom layer is where we live it's called the troposphere it begins at the surface of the earth and goes up from there to about 23,000 feet (7 km) at the poles or 56,000 feet (17 km) at the equator.
Ozone is mainly found in two regions of the earth's atmosphere most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the earth's. The presence of this field is of extreme importance to both earth's atmosphere and to life on earth as we know it map from the mars global surveyor of the current magnetic fields on mars credit: nasa/jpl. Earth's atmosphere consists of a number of layers that differ in properties such as composition, temperature and pressure the lowest layer is the troposphere, which extends from the surface to the bottom of the stratosphere. The earth's atmosphere is a thin layer of gases that surrounds the earth it composed of 78% nitrogen, 21% oxygen, 09% argon, 003% carbon dioxide, and trace amounts of other gases. Earth's atmosphere is 78% nitrogen, 21% oxygen, 09% argon, and 003% carbon dioxide with very small percentages of other elements our atmosphere also contains water vapor. The earths atmosphere layers are similar to the layers in the interior of the earth there are four major layers of atmosphere above the earth that are separated by temperature.
Geography4kidscom this tutorial introduces atmosphere basics other sections include climates, the biosphere, hydrosphere, the earth, and ecosystems. Atmosphere a planet's climate is decided by its mass, its distance from the sun and the composition of its atmosphere earth's atmosphere is 78% nitrogen, 21% oxygen, and 1% other gases. Without the atmosphere, we will not be able to live on earth the gases in the atmosphere protect us by blocking out dangerous rays from sun and making earth. Earth's atmosphere, which is around 300 miles thick, is mainly made of nitrogen and oxygen, although there are many other trace substances in its composition trace substances make up only 1 percent. Earth: earth, third planet from the sun and the fifth in the solar system in terms of size and mass the early evolution of the solid earth and its atmosphere and oceans is covered in geologic history of earth.
The atmosphere of the earth
A radiation shield the atmosphere of earth protects us and all living things on the earth from dangerous radiation from the sun in addition to the light we see, the sun also gives off ultraviolet radiation.
The thermosphere is a layer of earth's atmosphere the thermosphere is directly above the mesosphere and below the exosphere it extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet. Lack of oxygen did not hold back evolution of complex life was the bold announcement in the scientific news media recently. Earths atmosphere is the layer of gases that surrounds our planet gravity keeps the gases from drifting off into space three-quarters of the atmosphere is located within 11 kilometers of earth.
