d) Troposphere: the atmospheric layer that supports life. Home of the biosphere. Holds 90% of total mass of atmosphere and all water vapor, clouds, weather and air pollution.

What is the layer of earth and sky that supports life?
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.
Which layer of the atmosphere is most Favourable to support life?
Ozone Layer Makes Life Possible
Ozone in the upper atmosphere absorbs high-energy ultraviolet (UV) radiation coming from the Sun. This protects living things on Earth's surface from the Sun's most harmful rays. Without ozone for protection, only the simplest life forms would be able to live on Earth.
What does the atmosphere do to support life on earth?
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. ... The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.
What is the most important layer in the earth?
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.
What is stratosphere in Earth and life science?
The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. ... The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. The top of the stratosphere occurs at an altitude of 50 km (31 miles).
What is the Earth's stratosphere?
The stratosphere is a layer of Earth's atmosphere. The stratosphere is located above the troposphere and below the mesosphere.
What two layers protect the atmosphere?
Most of the important processes of the atmosphere take place in the lowest two layers: the troposphere and the stratosphere.
Which layer of the atmosphere can support life forms Why?
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.
Does atmosphere support life?
The atmosphere supports life and is also needed for the water cycle and weather. The gases of the atmosphere even allow us to hear.
How can we sustain life on Earth?
Sustaining life on earth is one of the biggest problems we are facing right now that is linked to three sustainability pillars: environment, social, economic. Living in harmony with nature requires an understanding of the concept of a sustainable community and accessibility to clean air, pure water, and fertile soil.
What layer of the Earth is the most important and why?
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. The troposphere contains about 85% of the atmosphere's total mass.
Why is the exosphere important to life on Earth?
Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.
What's in the stratosphere layer?
Almost all weather is in this region. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer.
Do we live in the stratosphere?
Humans live in the lowest layer called the troposphere. It is also the layer where all weather conditions occur. The layers above it are called the stratosphere, the mesosphere, and the thermosphere.
What does the mesosphere do?
The mesosphere is the highest of the atmospheric layers in which gases are all mixed up, instead of being layered in terms of their mass. 18. The mesosphere protects the Earth from meteors and asteroids by burning them up before they can reach its surface.
