SOLAR SYSTEM

Detailed explanation-1: -Higher up, in the stratosphere, the ozone layer absorbs solar ultra-violet radiation and affects how much of the Sun’s heat is radiated back into space. The ozone layer shields us from the harmful effects of excessive UV radiation, which can lead to sunburn, skin cancer and eye damage.

Detailed explanation-2: -The atmosphere surrounds the Earth and holds the air we breathe; it protects us from outer space; and holds moisture (clouds), gases, and tiny particles. In short, the atmosphere is the protective bubble in which we live.

Detailed explanation-3: -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. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.

Detailed explanation-4: -(i) What is the atmosphere? Answer: The blanket of air surrounding the earth is called the atmosphere. The atmosphere primarily comprises nitrogen and oxygen in bulk and other gases like carbon dioxide, helium, ozone, etc. in less quantities. All living beings on earth depend on the atmosphere for their survival.

Detailed explanation-5: -Beginning at the surface of Earth, the troposphere extends to around seven miles up. This is the layer we live in and contains most of what we consider to be “the atmosphere, ‘’ including the air we breathe and nearly all of the weather and clouds we see.

Detailed explanation-6: -The earth’s atmosphere protects the inhabitants by absorbing harmful solar rays and maintaining a steady temperature. It wards off many dangers of space thereby making life possible on earth. It is thus an important factor of climatic control and a life-sustaining source on earth.
