Environmental Science Quizzes & Trivia

The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous rays from reaching Earth. The atmosphere layer closest to the earth is referred to as the troposphere. What more do you know about our atmosphere? Take the quiz and test your knowledge.


Questions and Answers
  • 1. 

    Electrically charged atoms

    • A.

      Ions

    • B.

      Troposhpere

    • C.

      Conduction

    • D.

      Methane

    • E.

      Mesosphere

    Correct Answer
    A. Ions
    Explanation
    Ions are electrically charged atoms that can be found in various atmospheric layers, including the troposphere and mesosphere. In the troposphere, ions can be created through processes such as conduction, where charged particles transfer their charge to nearby atoms or molecules. Methane, a compound consisting of carbon and hydrogen, can also play a role in ion formation in the troposphere. Similarly, in the mesosphere, ions can be present due to various factors such as solar radiation and cosmic rays. Therefore, ions can be found in both the troposphere and mesosphere.

    How air is heated near Earth's surface

    • A.

      Ions

    • B.

      Troposphere

    • C.

      Conduction

    • D.

      Methane

    • E.

      Mesosphere

    Correct Answer
    C. Conduction
    Explanation
    Conduction is the process by which heat is transferred from one object to another through direct contact. In the context of air being heated near Earth's surface, conduction refers to the transfer of heat from the warmer ground to the cooler air molecules in the lower atmosphere. As the ground is heated by the sun, it transfers some of its thermal energy to the adjacent air molecules through direct contact. This process causes the air near the Earth's surface to become heated.

    One of the most abundant greenhouse gases

    • A.

      Ions

    • B.

      Troposphere

    • C.

      Conduction

    • D.

      Methane

    • E.

      Mesosphere

    Correct Answer
    D. Methane
    Explanation
    Methane is considered one of the most abundant greenhouse gases. Greenhouse gases trap heat in the Earth's atmosphere, contributing to the greenhouse effect and global warming. Methane is released from various sources, including natural processes like wetlands and human activities like agriculture and fossil fuel extraction. It has a high global warming potential, meaning it is very effective at trapping heat compared to other greenhouse gases. Methane is present in the troposphere, the lowest layer of the Earth's atmosphere, where most weather occurs. It does not conduct heat well, as conduction is the transfer of heat through direct contact, and methane is a gas. It is not found in the mesosphere, which is the layer above the stratosphere.

    The coldest layer of Earth's atmosphere

    • A.

      Ions

    • B.

      Troposphere

    • C.

      Conduction

    • D.

      Methane

    • E.

      Mesosphere

    Correct Answer
    E. Mesosphere
    Explanation
    The mesosphere is the coldest layer of Earth's atmosphere. It is located above the stratosphere and below the thermosphere. In this layer, temperatures can drop as low as -90 degrees Celsius. The mesosphere is characterized by the presence of ions, which are electrically charged particles. Conduction, the transfer of heat through direct contact, is not a significant factor in the mesosphere due to the low density of particles. Methane, a greenhouse gas, is not specifically associated with the mesosphere.

    The layer of Earth's atmosphere closest to the surface

    • A.

      Ions

    • B.

      Troposphere

    • C.

      Conduction

    • D.

      Methane

    • E.

      Mesosphere

    Correct Answer
    B. Troposphere
    Explanation
    The correct answer is troposphere because it is the layer of Earth's atmosphere that is closest to the surface. It is where weather phenomena occur and where temperature decreases with increasing altitude. The other options, such as ions, conduction, methane, and mesosphere, are not related to the layer closest to the Earth's surface.

  • 6. 

    In the troposphere, which of the following decreases as altitude increases?

    • A.

      Temperature

    • B.

      Radiation

    • C.

      Pressure

    • D.

      Both (a) and (c)

    Correct Answer
    D. Both (a) and (c)
    Explanation
    As altitude increases in the troposphere, both temperature and pressure decrease. This is because the troposphere is the lowest layer of the Earth's atmosphere and is closest to the surface. As you move higher in the troposphere, you are moving away from the heat source of the Earth's surface, causing the temperature to decrease. Additionally, as you move higher, there is less air above you, resulting in a decrease in atmospheric pressure. Therefore, both temperature and pressure decrease with increasing altitude in the troposphere.

    What gas do animals exhale?

    • A.

      Methane

    • B.

      Oxygen

    • C.

      Carbon dioxide

    • D.

      Nitrogen

    Correct Answer
    C. Carbon dioxide
    Explanation
    Animals exhale carbon dioxide as a waste product of cellular respiration. During respiration, animals take in oxygen and release carbon dioxide. This process occurs in the cells of their bodies to produce energy. Carbon dioxide is then transported to the lungs and exhaled out of the body through the respiratory system. Methane, oxygen, and nitrogen are not typically exhaled by animals. Methane is produced by certain microorganisms in the digestive systems of some animals, oxygen is inhaled by animals for respiration, and nitrogen is a major component of the Earth's atmosphere.

    What does the ozone layer absorb?

    • A.

      Ultraviolet radiation

    • B.

      Ions

      Aerosols

    • D.

      Greenhouse gases

    Correct Answer
    A. Ultraviolet radiation
    Explanation
    The ozone layer absorbs ultraviolet radiation. Ozone molecules are made up of three oxygen atoms and are located in the Earth's stratosphere. They have the ability to absorb most of the Sun's ultraviolet (UV) radiation, particularly the harmful UV-B and UV-C rays. This absorption helps to protect life on Earth from the damaging effects of excessive UV radiation, such as skin cancer, cataracts, and harm to marine ecosystems.
