Which Best Describes the Composition of the Atmosphere of Earth

Carbon dioxide and water vapor in atmosphere trap infrared radiation re-reflecting it back toward earth. Click the video below to know in detail about the composition of the air.

What S The Atmosphere Made Of Quora

Dry air from earths atmosphere contains 0038 of carbon dioxide 2095 of oxygen 7808 of nitrogen and 093 of argon.

. Changes in Composition Earths primordial atmosphere was probably similar to the gas cloud that created the sun and planets. This helps to keep Earth warm. The air encompasses the earth from all sides.

Earths atmosphere has six layers. The Earth formed with the Sun 46 billion years ago. ÎThose gases eventually escaped to the space.

Origins of the Atmosphere When the Earth was formed 46 billion years ago Earths atmosphere was probably mostly hydrogen H and helium He plus hydrogen compounds such as methane CH 4 and ammonia NH 3. The release of gases from rock through volcanic eruption so-called. It is one of the building blocks of life as it is the major component of protein.

A variable amount of water vapour is also present in the atmosphere approx1 at sea level and it decreases with altitude. Earths atmosphere is similar to a jacket for our planet. The greatest proportion of volcanic gases are made up of carbon dioxide water vapour and ammonia.

The dominance of Banded. The Early atmosphere was probably dominated at first by water vapor which as the temperature dropped would rain out and form the oceans. The composition of Earths atmosphere is determined by the by-products of the life that it sustains.

1 In chemistry a compound is a substance that results from a combination of two or more different chemical element s in such a way that the atom s of the different elements are held together. It surrounds our planet keeps us warm gives us oxygen to breathe and it is where our weather happens. For decades scientists believed that the atmosphere of early Earth was highly reduced meaning that oxygen was greatly limited.

Its early atmosphere was probably formed from the gases given out by volcanoes. When earth was first formed its atmosphere was likely composed of hydrogen helium and other gases that contained hydrogen. The atmosphere of earth is composed of nitrogen 78 oxygen 21 argon 09 carbon dioxide 004 and trace gases.

The atmosphere is a thin layer of gases that surround the Earth which absorbs radiation and moderates climate. Nitrogen makes up 78 of the earths atmosphere Oxygen makes up 21 of the earths atmosphere. What describes a compound.

Then the atmosphere was dominated by nitrogen but there was certainly no oxygen in the early atmosphere. It consisted of hydrogen and helium along with methane ammonia and water. Dry air mixture of gases from Earths atmosphere contains 7808 nitrogen 2095 oxygen 093 argon 004 carbon dioxide and traces of hydrogen helium and other noble gases by volume but generally a variable amount of water vapor is also present on average.

As the ocean warms due to climate change it holds less CO2 from the atmosphere and because of this CO2 concentrations in the atmosphere increase over time. The troposphere the stratosphere the mesosphere the thermosphere the ionosphere and the exosphere. These constant gases are nitrogen oxygen and argon.

The ocean is a sink for carbon dioxide. Form the remaining part of the atmosphere. See the explanation below.

The planet is generally thought of as having three distinct atmospheres over the course of its lifetime. You should understand that most of the gases in the atmosphere are nitrogenand oxygen. Traces of hydrogen neon helium nitrous oxide ozone and other noble gases but generally a variable amount of water vapour is also present on average about 1 at sea level.

The air is a mixture of sev-eral gases. The Earths atmosphere is mostly composed of a mixture of gases with very tiny quantitiesof aerosols which are solid or liquid particles suspended in the air. The major components of nitrogen oxygen and argon remain constant over time and space while trace components like CO 2 and water vapor vary considerably over both space and time.

A material that is made up of a combination of atoms bonded together best describes a compound. The atmosphere is a mixture of different types of gases. Nitrogen and oxygen are the two main gases in the atmosphere and 99 percentage of the atmosphere is made up of these two gases.

Such oxygen-poor conditions would have resulted in an atmosphere filled with noxious methane carbon. Atmosphere Composition and Structure Notes The domain of Air on the Earth GEOGRAPHY 9 ATMOSPHERE COMPOSITION AND STRUCTURE Earth is a unique planet because the life is found only on this planet. What makes up most of the Earths Atmosphere.

These will be referred to as the major components of the atmosphere. Earths atmosphere is made up of a combination of gases. This would have been a deluge of truly global proportions an resulted in further reduction of CO2.

Other gases like argon carbon dioxide neon helium hydrogen etc. Yet this atmosphere didnt last for very long because the solar wind from the sun blew it away. What Best Describes A Compound.

The Earths atmosphere consists of a mixture of noble gas atoms and many kinds of molecules. Oxygen makes up about 21 and is absolutely necessary for plant and animal respiration. Nitrogen in the atmosphere makes up about 78 of the total composition of the atmosphere.

This was a reducing atmosphere. Carbon dioxide gas is largely responsible for the greenhouse effect. At this point it was nothing more than a molten ball of rock surrounded by an atmosphere of hydrogen and helium.

The air has a special place among the conditions necessary for life.
