Answers
Answer:
the earth sorrounded the huge blanket of air is called atmosphere
Answer:
The atmosphere is the blanket of gases which surrounds Earth. It is held near the surface of the planet by Earth's gravitational attraction.
Oxygen and Carbon Dioxide
Life on Earth needs the atmosphere to breath. Animals take in breathable oxygen from the atmosphere and use it to metabolize food into energy. Plants use carbon dioxide to grow and sustain life. The balance between these two gases is important as well: animals need enough oxygen to breathe and plants need carbon dioxide, but too much carbon dioxide traps heat in the atmosphere, leading to global warming.
Protection
The Earth's average temperatures would fall below the freezing point of water without atmospheric gases to hold enough heat. The balance between blocked radiation and radiation allowed to reach the Earth makes life possible.
Other Benefits
The atmosphere contains a large amount of nitrogen. Some plants take nitrogen straight from the air and use it to build nutrients needed for growth. Atmospheric wind erodes land so it can be broken down to form life-sustaining soil.
