Answer:
1. the atmosphere protects earth from harmful solar radiations and regulates heating provide by the sun.
Answer:
1. 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.
3.Atmospheric Gases are Indispensable for Life on EarthEdit
Carbon dioxide (CO2) and oxygen (O2) are the most important gases for living organisms. CO2 is vital for use by plants in photosynthesis, in which plants use CO2 and water to convert the Sun's energy into food energy.
4. 1 Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
2. Troposphere—meaning “sphere of change” or “sphere of turning”—is so named because this turbulent, chaotic zone is full of moving air currents, clouds, storms, and other weather phenomena. quarterfreelp and 2 more users found this answer helpful.
3. It is because when they climb mountains, as altitude increases, the amount of oxygen level in the atmospheric air decreases as trees are not found at higher altitudes. The air pressure gets lower as the altitude increases.
