Earths Gravity Atmosphere Quiz Questions - Quiz


The gas molecules and other particles in the atmosphere are bound by gravity to the host planet or satellite. The force of gravity is the weakest at the equator because of the centrifugal force caused by the Earth's rotation. Test out what else you know about our gravitational pull and atmosphere below.


Questions and Answers
  • 1. 

    What do we call the layer of gases that surrounds the Earth?

    • A.

      Hemisphere

    • B.

      Biosphere

    • C.

      Atmosphere

    • D.

      Ozone

    Correct Answer
    C. Atmosphere
    Explanation
    The correct answer is "Atmosphere." The atmosphere refers to the layer of gases that surrounds the Earth. It is composed of various gases, such as nitrogen, oxygen, carbon dioxide, and others. The atmosphere plays a crucial role in protecting the Earth from harmful radiation, regulating temperature, and providing the necessary gases for life to exist.

  • 2. 

    1.     Why is the atmosphere important? (choose the best answer)

    • A.

      It gives us the air we breathe.

    • B.

      It keeps the temperatures on Earth comfortable.

    • C.

      It protects us from the sun’s harmful UV radiation.

    • D.

      All of the above.

    Correct Answer
    D. All of the above.
    Explanation
    The atmosphere is important for several reasons. Firstly, it provides us with the air we breathe, which is essential for our survival. Secondly, it helps regulate temperatures on Earth, making the climate more suitable for life. Lastly, the atmosphere acts as a shield, protecting us from the sun's harmful UV radiation. Therefore, all of the given options are correct and contribute to the importance of the atmosphere.

  • 3. 

    1.     Identify the four layers of atmosphere in order from closest to the Earth to furthest.

    • A.

      Troposphere, Stratosphere, Mesosphere, Thermosphere.

    • B.

      Stratosphere, Troposphere, Mesosphere, Thermosphere.

    • C.

      Troposphere, Stratosphere, Thermosphere, Mesosphere.

    • D.

      Stratosphere, Troposphere, Thermosphere, Mesosphere.

    Correct Answer
    A. Troposphere, Stratosphere, Mesosphere, Thermosphere.
    Explanation
    The correct order of the four layers of the atmosphere from closest to the Earth to furthest is Troposphere, Stratosphere, Mesosphere, Thermosphere.

    Rate this question:

  • 4. 

    1.     Where can the ozone layer be found?

    • A.

      In the troposphere.

    • B.

      In the stratosphere.

    • C.

      In the thermosphere.

    • D.

      In the mesosphere.

    Correct Answer
    B. In the stratosphere.
    Explanation
    The ozone layer is found in the stratosphere. The stratosphere is the second layer of the Earth's atmosphere, located above the troposphere. The ozone layer is a region within the stratosphere that contains a high concentration of ozone molecules. It plays a crucial role in absorbing the majority of the Sun's ultraviolet (UV) radiation, protecting life on Earth from harmful UV rays.

    Rate this question:

  • 5. 

    1.     What is the function of the ozone layer?

    • A.

      It allows the sun’s rays to hit the Earth and warm it up.

    • B.

      It absorbs and scatters the sun’s UV radiation so the harmful rays don't hit Earth.

    • C.

      It helps produce clouds.

    • D.

      It can destroy incoming meteorites that may hit Earth.

    Correct Answer
    B. It absorbs and scatters the sun’s UV radiation so the harmful rays don't hit Earth.
    Explanation
    The ozone layer acts as a protective shield for the Earth by absorbing and scattering the sun's UV radiation. This prevents the harmful rays from reaching the Earth's surface and causing damage to living organisms.

    Rate this question:

  • 6. 

    What is the atmosphere mainly comprised (made up) of?

    • A.

      Oxygen and carbon dioxide

    • B.

      Oxygen and nitrogen

    • C.

      Carbon dioxide and nitrogen

    • D.

      Methane and oxygen

    Correct Answer
    B. Oxygen and nitrogen
    Explanation
    The atmosphere is mainly comprised of oxygen and nitrogen. Oxygen makes up about 21% of the atmosphere, while nitrogen makes up about 78%. These two gases are the most abundant in the Earth's atmosphere and are essential for supporting life.
