What are the function of the atmosphere?

What are the function of the atmosphere?

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.

What are the parts of the atmosphere?

Earth’s atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space.

What are four functions of the atmosphere?

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 (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation …

What is the function of atmosphere in the environment?

The atmosphere protects Earth from harmful solar radiations and regulates heating provided by the Sun. The first function is made possible by ozone existing in the stratosphere, the second function is achieved by a mix of gases existing in the whole atmosphere called “greenhouse gases”.

What is atmosphere explain?

An atmosphere is the layers of gases surrounding a planet or other celestial body. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

What are the 5 types of atmosphere?

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

What is the atmosphere short answer?

The atmosphere is the blanket of gases which surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. Without the atmosphere there could be no life on Earth. keeps the climate on Earth moderate compared to that of other planets.

What is the function of the atmosphere in the environment class 7?

The atmosphere contains the air that we breathe; protects us from the harmful radiation of the Sun; helps to keep the planet’s heat on the surface, and plays a very important role in the water cycle.

What are the two functions of our atmosphere Why is it important?

The Earth’s atmosphere protects and sustains the planet’s inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun’s energy and wards off many of the dangers of space.

What is atmosphere one word answer?

Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.

What are the 7 layers of atmosphere?

Layers of the atmosphere

• The Troposphere. This is the lowest part of the atmosphere – the part we live in.
• The Stratosphere. This extends upwards from the tropopause to about 50 km.
• The Mesosphere. The region above the stratosphere is called the mesosphere.
• The Thermosphere and Ionosphere.
• The Exosphere.
• The Magnetosphere.
