How does the troposphere support life on Earth?

The troposphere is the only atmospheric layer that can support life. The higher layers have filtered out the harmful radiation, and there are large amounts of water vapor. This is the layer where clouds develop, birds fly, and pollution collects. Yes, the troposphere is where humans most pollute the atmosphere.

What are some important facts about the troposphere?

Fact Sheet

• The troposphere contains 75\% of the atmosphere’s total mass.
• In either space or time the troposphere is not constant.
• Weather occurs in the troposphere.
• The troposphere is 10 miles from the equator.
• The troposphere is 5-7 miles above the poles.
• Does not contain ozone.

Why is atmosphere important for us 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. Plants require carbon dioxide for photosynthesis; they use sunlight to change carbon dioxide and water into food.

Why is troposphere the most important of all the layers of the atmosphere Class 11?

It is most important layer of the atmosphere because: Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents. This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer.

Why is the troposphere important to weather on Earth?

The water cycle also occurs in this layer of the atmosphere. The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.

How is atmosphere important for us Class 7?

How is environment important to us Class 7 Geography?

Environment is important to us because it provides the air we breathe, the water we drink, the food we eat and the land where we live.

What is the importance of atmosphere in Short answer?

The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun’s dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.

Why is troposphere the most important of all the layers of the atmosphere Brainly?

Troposphere emphasizes on making the atmosphere on the earth suitable for living things to prevail. It is the most important of all the layers as it regulates the temperature on earth’s surface and it is the reason for safe survival of life on the earth.

Why troposphere is the most important layer of the atmosphere Class 7?

Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere absorbs most of the heat radiated by the Earth’s surface, thereby, maintaining the temperature of the surface.

Why is troposphere very important for life forms on the earth explain with respect to weather and climate?

Importance of troposphere to life on earth The study of the troposphere is very important because we breathe the air in this layer of air. Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.

What is troposphere class 7th?

Troposphere. The troposphere is the layer that starts from the surface earth and it extends up to 8-15 km in height. Around 80\% of the mass of the atmosphere is in the troposphere which is heated by the surface of the Earth.

Why troposphere is the hotest part of the atmosphere?

It is heated by the Earth’s surface The troposphere is the layer of the atmosphere closest to the earth’s surface where the weather takes place. The warmest temperatures in the troposphere are near the surface with the coldest temperatures being at the top of the troposphere.

What are facts about the stratosphere?

Interesting Stratosphere Facts: The stratosphere is one of five layers of the atmosphere. The word ‘stratosphere’ is derived from the word ‘strato’ meaning layer, and ‘sphere’ which is earth’s shape. The stratosphere accounts for approximately 24\% of the earth’s total atmosphere.

Why is the thermosphere impontant to life on Earth?

The thermosphere is very important for human life as it contributes enormously to protecting the earth, as well as enabling space exploration and modern forms of communication. It recycles water, absorbs the sun’s energy and creates a moderate temperature. This helps protect the earth from the extremely cold temperatures that come from space.

Why is the thermosphere important to the Earth?

The thermosphere is a layer of the Earth’s atmosphere situated directly above the mesosphere and below the exosphere. The thermosphere performs several important functions, such as temperature regulation and filtering powerful X-rays and ultraviolet radiation emitted by the sun.
