Q:

What is the function of the atmosphere?

A:

Quick Answer

The atmosphere works as a place to contain the oxygen that is necessary for life, works as a blanket to shield the earth from radiation and helps to create the different types of weather that are felt on the Earth. The atmosphere also contains small amounts of carbon dioxide that is necessary for plants to be able to live.

Full Answer

Without the atmosphere that protects the Earth, humans, animals and all plant life would not be able to survive. The atmosphere works to hold oxygen in the area around the earth. Humans and most animals are dependent on oxygen. Plants are also dependent on oxygen because they take the leftover carbon dioxide from humans when they inhale the oxygen. Radiation is another important factor for the Earth's survival. It is necessary for survival of plants and animals that there be some type of radiation from sunlight, but too much radiation can cause major problems that are mostly associated with overheating of the Earth. The atmosphere forms a blanket around the Earth that prevents too much radiation from entering the earth. The blanket that it provides is also responsible for the weather that is seen on the Earth. The atmosphere works to create cool breezes and the rain that is necessary for plants to grow and animals to remain hydrated.

  • Q:

    How much oxygen is in the air?

    A:

    Since the atmosphere has a mass of approximately 5.15 x 10^18 kilograms, the total mass of oxygen in the atmosphere is approximately 1.08 x 10^18 kilograms. Oxygen makes up approximately 20.9 percent of the Earth's atmosphere.

  • Q:

    What percentage of the air we breathe is oxygen?

    A:

    The air that makes up Earth's atmosphere contains 20.9 percent oxygen. This is true up to about 70,000 feet above sea level. However, above 10,000 feet, the atmosphere becomes too thin to support human life, even though its proportions do not change much.

  • Q:

    How does the hydrosphere affect the atmosphere?

    A:

    Evaporated water from the hydrosphere gets stored in the atmosphere, which later releases the water back to the surface of the Earth in the form of precipitation. Water evaporates in warm areas, and the water vapor rises up into the atmosphere. Once there, the water can travel great distances and eventually gets dumped back onto the Earth.
