How Do You Describe the Amount of Air Changes As You Move Through the Earth's Atmosphere? Quick Answer. The thickest layer of the atmosphere is the troposphere, which averages 11 miles high at the equator and is thinner at the poles. All the weather occurs in this layer, and the troposphere contains nearly 80 percent of the air in the Earth's atmosphere. Above the troposphere, in ascending order, is the stratosphere, mesosphere, thermosphere and exosphere.

Atmosphere of Earth Atmosphere of Earth. 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, absorbing ultraviolet solar radiation, warming the surface through heat retention, and reducing temperature extremes between day and night. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

What Is The Atmosphere? The atmosphere consists of 78% nitrogen, 21% oxygen, 1% water vapor, and a minute amount of other trace gases like argon, and carbon monoxide. All of these gases combine to absorb ultraviolet radiation from the Sun and warm the planet’s surface through heat retention. The mass of the atmosphere is around 5×1018kg.

Atom The troposphere contains 75 percent of atmosphere's mass-on an average day the weight of the molecules in the air is14.7 lb..(sq. in.)- and most of the atmosphere's water vapor.ater vapor plays a major role in regulating air temperature because it absorbs solar energy and thermal radiation from the planet's surface. The troposphere contains 99% of the water vapor in the atmosphere. Water vapor concentrations vary with latitudinal position(north to south).

An Explanation of Pressure and the Laws  of Boyle, Charles, Dalton, and Henry Earth's atmosphere is composed of air. Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components. We usually model air as a uniform (no variation or fluctuation) gas with properties that are averaged from all the individual components.

- Although the weight of the atmosphere is only about one millionth the weight of the earth, it does exert a force or pressure on the surface of the earth. A square inch column of air weighs approximately 14.7 lbs. at sea level.This weight diminishes with height.HE TROPOSPHERE. This is the lowest layer of the atmosphere, and varies in height in different spans of the world from roughly 28,000 feet above sea level at the poles to 54,000 feet at the equator.

Earth's Atmosphere: Composition, Climate & Weather Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).arth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface.

- By definition, atmospheric or air pressure is the force per unit of area exerted on the Earth’s surface by the weight of the air above the surface. The force exerted by an air mass is created by the molecules that make it up and their size, motion, and number present in the air.

Introduction Most of the earth's atmosphere (80 to 90%) is found in the troposphere, the atmospheric layer where we live. This layer, where the earth's weather occurs, is within about 12 km (7 miles) of the earth's surface. The stratosphere goes up to about 53 km (29 miles).

Atmosphere of Venus The amount of nitrogen in the atmosphere is relatively small compared to the amount of carbon dioxide, but because the atmosphere is so much thicker than that on Earth, its total nitrogen content is roughly four times higher than Earth's, even though on Earth nitrogen makes up about 78% of the atmosphere.

Structure The Atmosphere is divided into layers according to major changes in temperature. Gravity pushes the layers of air down on the earth's surface. This push is called air pressure. 99% of the total mass of the atmosphere is below 32 kilometers. Troposphere - 0 to 12 km - Contains 75% of the gases in the atmosphere.

Insects in High Oxygen Environments Low an d High Pressure. Air pressure is not uniform across the Earth however. The normal range of the Earth's air pressure is from 980 millibars (mb) to 1050 mb. These differences are the result of low and high air pressure systems which are caused by unequal heating across the Earth's surface and the pressure gradient force.

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.he exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft).

- The density of air, (Greek: rho) (air density), is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in temperature or humidity. At sea level and at 15 °C air has a density of approximately 1.225 kg/m3 (0.001225 g/cm3, 0.0023769 slug/ft3, 0.0765 lbm/ft3) according to ISA (International Standard Atmosphere).

Atom The glaciers of Glacier National Park, lakes, rivers, and streams—and even the moisture in the air is part of the hydrosphere. The atmosphere is the air around us. “Atmo” is the Greek word for air. The atmosphere is made up of 79% nitrogen and almost 21% oxygen: the rest is carbon dioxide and other gasses.
