Complete answer: - Atmosphere is essential for life because it has oxygen and other useful gases which humans need for their survival. ... It has most of the ozone present in the atmosphere. The increase in temperature with height happens because of the absorption of ultraviolet radiation from the sun by the ozone layer.

Why is the atmosphere essential for life for class 9th?
Answer: Atmosphere is very important for sustaining life: It contains various gases like O2, CO2, N2 which are required for various life processes by plants and animals. (ii) gas is used by plants to prepare food by the process called photosynthesis (iii) Oxygen is required for burning, combustion and respiration.
Why is atmosphere essential for life Brainly?
It blocks the harmful sun rays from reaching earth. It traps heat , making earth a comfortable temperature. And the oxygen within our atmosphere is essential for life. Hence,the atmosphere is essential for life.
Why is atmosphere essential for our life state 3 reason?
The atmosphere is essential for life for the following reasons: (a) Oxygen which is essential for the survival of all living organisms is present in the atmosphere. (b) Essential gases that support life on the earth are present in the atmosphere. (c) Water cycle would not have been possible without the atmosphere.
Why is the atmosphere essential for life short answer?
The atmosphere is essential for life for the following reasons: (a) Oxygen, which is essential for the survival of all living organisms, is present in the atmosphere. (b) Essential gases that support life on the earth are present in the atmosphere. (c) Water cycle would not have been possible without the atmosphere.
Does atmosphere provide chemicals needed for life?
radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide. Small planets and moons have insufficient gravity to hold an atmosphere. ... Earth's atmosphere is about 100 miles thick. It keeps the surface warm & protects it from radiation & small- to medium-sized meteorites.
What is the difference between troposphere and stratosphere explain?
The troposphere is the lowest level of the atmosphere, so it is in contact with the Earth's surface. In contrast, the stratosphere is located above the troposphere, so it is not in contact with the Earth's surface. ... The air density and air pressure are much lower in the stratosphere.
Is there gravity in the atmosphere?
Gravity. Fortunately for us, Earth's gravity is strong enough to hold onto its atmosphere. Mars, for example, is less than half Earth's size and around one-tenth Earth's mass. ... Yes, Earth's atmosphere has weight.
Do you think that atmosphere is essential for life to sustain on Earth?
The atmosphere is made of gases that are essential for photosynthesis and other life activities. The atmosphere is a crucial part of the water cycle. It is an important reservoir for water, and the source of precipitation. The atmosphere moderates Earth's temperature.
What is the requirement of atmosphere for life to exist?
Complex, multicellular life on Earth needs an atmosphere for either respiration or photosynthesis. Even aquatic species rely on dissolved oxygen from the air. Photosynthesis, in contrast, requires carbon dioxide, also from the atmosphere.
Why does the atmosphere help sustain and protect life on the Earth surface?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth.
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.
How does the atmosphere make Earth livable?
The atmosphere helps make Earth livable by providing gases for respiration, being a shield against solar radiation, and insulating the planet from extreme temperatures.
What does the atmosphere protect us from which layer?
Stratosphere. Located between approximately 12 and 50 kilometers (7.5 and 31 miles) above Earth's surface, the stratosphere is perhaps best known as home to Earth's ozone layer, which protects us from the Sun's harmful ultraviolet radiation.
How does an atmosphere affect the surface of a planet and the ability of life to exist?
The fact that the atmosphere exists means that the Earth has air pressure (otherwise the planet would be in a vacuum) and also have the gases necessary for life to exist on Earth (oxygen and carbon dioxide).
Why does the atmosphere exist?
Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes, acting like a duvet wrapped around the planet.
Can you have an atmosphere without gravity?
Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space. ... Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space. In other words, no one would last long if the planet didn't have gravity.
Why is there no atmosphere in space?
This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears. ... Even the emptiest parts of space contain at least a few hundred atoms or molecules per cubic metre.
