Atmosphere The atmosphere helps to protect living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays. The current composition of the Earth's atmosphere is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms.

WHAT DOES THE ATMOSPHERE DO? 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. Much of it is filtered out by the atmosphere.

- The Earth cools down by giving off a different form of energy, called infrared radiation. But before all this radiation can escape to outer space, greenhouse gases in the atmosphere absorb some of it, which makes the atmosphere warmer. As the atmosphere gets warmer, it makes the Earth's surface warmer, too. Learn more about radiation. Learn where the term “greenhouse effect” comes from. Greenhouse gases keep the Earth warm through a process called the greenhouse effect.

Earth's Atmosphere The atmosphere is a mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth. High above the planet, the atmosphere becomes thinner until it gradually reaches space. It is divided into five layers.

- A: 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 of the bulk of the atmosphere while nitrogen (78 percent), oxygen (21 percent) and argon (1 percent) make up the rest. Continue Reading

- What makes Earth's climate so moderate? Separating Earth from the extreme and inhospitable climate of space is a 500-mile-thick cocoon of gases called the atmosphere. All planets have an atmosphere, a layer of gases that surrounds them. The Sun's atmosphere is made up of hydrogen, while Earth's is made up primarily of nitrogen and oxygen. Carbon dioxide, ozone, and other gases are also present. These gases keep our planet warm and protect us from the direct effects of the Sun's radiation. Without this regulation, Earth could not sustain life.

What does the Atmosphere do??? The Atmosphere is a huge ‘blanket’ of air over the Earth, which consists of five layers. These layers are; Exosphere, the Thermosphere, the Mesosphere, the Stratosphere and the Troposphere. The Exosphere is the outer layer around the Earth.The air is very thin as the air particles are far apart.Beyond the Exosphere, is outer space.

Atmosphere of Earth Report. The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.

WHAT DOES THE ATMOSPHERE DO? We need oxygen to keep our bodies working. Just try holding your breath for a few seconds and see what happens. People are not the only ones who need oxygen; all kinds of animals need it too. Without the atmosphere we would all quickly die. But that's not the only thing the atmosphere does for us. 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. Much of it is filtered out by the atmosphere.

High School Earth Science/The Atmosphere 1 Without its atmosphere, Earth would be a very different planet. 2  Gases in the atmosphere allow plants to photosynthesize and animals and plants to engage in respiration. 3  Water vapor, which is an atmospheric gas, is an essential part of the water cycle. 4  All weather takes place in the atmosphere.

Introduction to the Atmosphere 1 The earth's atmosphere is a very thin layer wrapped around a very large planet.  Two gases make up the bulk of the earth's atmosphere: nitrogen (), which comprises 78% of the atmosphere, and oxygen (), which accounts for 21%. Various trace gases make up the remainder.

What Is The Atmosphere? The atmosphere is also responsible for the aurora borealis. Auroras are caused by the bombardment of solar electrons on oxygen and nitrogen atoms in the atmosphere. The electrons literally excite the oxygen and nitrogen atoms high in the atmosphere to create the beautiful light show we know as an aurora.

High School Earth Science/The Atmosphere Without the atmosphere, planet Earth would be much more like the Moon than like the planet we live on today. The Earth's atmosphere, along with the abundant liquid water on the Earth's surface, are keys to our planet's unique place in the solar system. Much of what makes Earth exceptional depends on the atmosphere.

Layers of the Atmosphere The earth is surrounded by the atmosphere, which is the body of air or gasses that protects the planet and enables life. Most of our atmosphere is located close to the earth's surface where it is most dense. The air of our planet is 79% nitrogen and just under 21% oxygen; the small amount remaining is composed of carbon dioxide and other gasses. There are five distinct layers of the earth. Let's look at each, from closest to farthest from the earth.

What is a greenhouse? Earth's atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight.At night, Earth's surface cools, releasing the heat back into the air.ases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does.

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).Gravity is the reason the atmosphere is more dense closer to the earth's surface.his layer, where the earth's weather occurs, is within about 12 km (7 miles) of the earth's surface.

Earths Atmosphere Layers Earths Atmosphere Layers. 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. Each layer of the layers are separated by an increasing or decreasing temperature of the gases in the layer. The tropopause, stratopause, mesopause are areas where two atmosphere layers gradually transition from one layer into another layer.

THE ATMOSPHERE AND WEATHER THE ATMOSPHERE AND WEATHER. Air surrounds the earth and extends out for about 1,000 miles, gradually fading into space at that point. It is called the atmosphere. The air gets thinner the farther it is from the earth. It has no color, no smell and no taste but it is really several gases mixed together. You cannot see it, yet it is as real as land and water. The atmosphere is made up of 78 per cent nitrogen and 21 per cent oxygen. The remaining 1% consists of small amounts of argon and other gases. The atmosphere is divided into several layers with the Troposphere being the lower level. It extends up to about eight miles or 42,000 feet. It is the region of most weather. The Stratosphere extends to about 25 miles. It is a stable area with minimum temperatures and little change.
