what protects the earth atmosphere?

The ozone layer is a section of the Earth's atmosphere that acts as a barrier between the Earth and UV radiation. The ozone layer protects the Earth from too much radiation by both absorbing and reflecting harmful UV rays.

(a) Oxygen which is essential for the survival of all living organisms is present in the atmosphere. ... (d) The atmosphere acts as a protective blanket for the earth by blocking the harmful UV rays from the sun. (e) The temperature on the earth is maintained because of the presence of the atmosphere.

Forests are the 'lungs ' of the earth because they supply oxygen to the atmosphere. ... Trees and forests protect the land from erosion. They protect homes, farms, and coastlines from strong winds and waves. They make soils fertile, keep air, streams and lagoons clean and clear, and provide habitats and food for animals.

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. Up to about 80 km, the composition of atmosphere is highly uniform; therefore, the term homosphere is applied.

The ozone layer, located in Earth's stratosphere miles above the ground, shields the planet from much of the sun's damaging ultraviolet radiation.

The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. ... The atmosphere also helps to sustain life of Earth. It provides oxygen for humans and animals to breathe, and carbon dioxide for plants.

Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor.
1332852
The mixture of gases surrounding the Earth or other celestial body, held in place by gravity. ... The Earth's atmosphere consists, in ascending order, of the troposphere (containing 90% of the atmosphere's mass), the stratosphere, the mesosphere, the thermosphere, and the exosphere.

The atmosphere is essential for life because it maintains an appropriate climate for the sustenance of life by carrying out the following activities: (i) Atmosphere keeps the average temperature of the Earth fairly constant during day time. (ii) It prevents a sudden increase in temperature during day time.

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.

Earth's atmosphere. Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.

The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. The atmosphere has no abrupt cut-off. It slowly becomes thinner and fades away into space. There is no definite boundary between the atmosphere and outer space.

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.

The size of our planet allows an atmosphere that puts pressure at sea level, keeping the oceans from boiling away. The two characteristics are suitable atmospheric pressure and temperature.
572212
The Earth's atmosphere is the relatively thin layer of gases that surround the planet. It provides us with the oxygen we need to stay alive. The three most abundant gases (the ones with the highest percentages) are all elements: ... 21% oxygen, O.

(Without the atmosphere, the average temperature on Earth would be below freezing!) The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. ... The atmosphere also helps to sustain life of Earth. It provides oxygen for humans and animals to breathe, and carbon dioxide for plants.
