SOLAR SYSTEM

Detailed explanation-1: -Without it, life as we know it wouldn’t exist. 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.

Detailed explanation-2: -Without atmosphere life would not be possible as atmosphere protects us from harmful gases. We could not live without air present in atmosphere. In absence of the atmosphere, the earth would get so cold at night that we would not be able to survive.

Detailed explanation-3: -The atmosphere is a mixture of gases that surrounds the Earth. It helps make life possible by providing us with air to breathe, shielding us from harmful ultraviolet (UV) radiation coming from the Sun, trapping heat to warm the planet, and preventing extreme temperature differences between day and night.

Detailed explanation-4: -In the absence of an atmosphere, there would be no life, wind, or fires. The temperature would range from-190 degrees celsius to 110 degrees Celsius. It would increase during the day and decrease at night.

Detailed explanation-5: -Option a: Troposphere is regarded as the most important layer of atmosphere. It is the lowermost layer of the atmosphere and contains 75% of all air in the atmosphere. Most clouds occur in this layer because 99% of the water vapour in the atmosphere is found here.

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.
