  • 2. 

    Which element is most abundant in Earth's atmosphere?

    • Oxygen

    • Nitrogen

    • Carbon

    • Helium

    Correct Answer
    A. Nitrogen
    Explanation
    Nitrogen makes up 78% of the atmosphere

  • 3. 

    Airplanes fly in which layer(s) of the atmosphere?

    • Stratosphere

    • Troposphere and stratosphere

    • Stratosphere and mesophere

    • Mesosphere and troposphere

    Correct Answer
    A. Troposphere and stratosphere
    Explanation
    Airplanes fly in the troposphere and stratosphere layers of the atmosphere. The troposphere is the lowest layer of the atmosphere, extending from the Earth's surface up to about 10-15 kilometers. This is where weather phenomena occur and where most commercial airplanes fly. The stratosphere is the layer above the troposphere, extending from about 10-15 kilometers up to about 50 kilometers. It contains the ozone layer and provides stable conditions for long-distance flights. Therefore, airplanes operate in both the troposphere and stratosphere layers of the atmosphere.

    A man hiked to the top of Mount Rogers, the highest point in Virginia.  As he climbed, what happened? 

    • The thermal energy was increasing

    • The altitude of the mountain was decreasing

    • The temperature of the atmosphere was decreasing

    • The pressure of the atmosphere was increasing

    Correct Answer
    A. The temperature of the atmosphere was decreasing
    Explanation
    As the man hiked to the top of Mount Rogers, the highest point in Virginia, the temperature of the atmosphere was decreasing. This is because temperature generally decreases with an increase in altitude. As the man climbed higher, he reached a colder region of the atmosphere where the temperature was lower than at the base of the mountain.

  • 5. 

    Which layer of Earth's atmosphere contains a majority of the clouds?

    • Troposphere

    • Stratosphere

    • Mesosphere

    • Thermosphere

    Correct Answer
    A. Troposphere
    Explanation
    The troposphere is the layer of Earth's atmosphere closest to the surface. It is where weather occurs and where the majority of clouds are found. This layer is characterized by decreasing temperature with increasing altitude, which allows for the formation of clouds due to the condensation of water vapor. The other layers of the atmosphere, including the stratosphere, mesosphere, and thermosphere, do not contain as many clouds as the troposphere.

    A low reading on a barometer is associated with what?

    • Stormy weather

    • Dry weather

    • Hot weather

    • Fair weather

    Correct Answer
    A. Stormy weather
    Explanation
    A low reading on a barometer indicates a decrease in atmospheric pressure. This decrease in pressure is typically caused by the approach of a storm system, which is associated with stormy weather. Therefore, a low reading on a barometer is a reliable indicator of impending stormy weather.

    Which layer of the atmosphere protects us from meteors?

    • Ionosphere

    • Stratosphere

    • Troposphere

    • Mesosphere

    Correct Answer
    A. Mesosphere
    Explanation
    The mesosphere is the layer of the atmosphere that protects us from meteors. Meteors burn up upon entering the Earth's atmosphere due to the high temperatures caused by friction with the gases in the mesosphere. This layer is located above the stratosphere and below the thermosphere. It is characterized by low temperatures and is the layer where most meteors disintegrate before reaching the Earth's surface. Therefore, the mesosphere acts as a shield, preventing meteors from causing any significant damage to the Earth.

    Carbon dioxide trapping heat in the atmosphere is known as what?

    • The ozone layer

    • Pollution

    • The greenhouse effect

    • Smog

    Correct Answer
    A. The greenhouse effect
    Explanation
    The correct answer is the greenhouse effect. This is the process in which carbon dioxide and other greenhouse gases trap heat in the Earth's atmosphere, causing the planet to warm up. The greenhouse effect is responsible for the Earth's average temperature being suitable for life as we know it.

    What would be the forecast for an area experiencing high barometric pressure?

    • Sunny

    • Stormy

    • Rainy

    • Windy

    Correct Answer
    A. Sunny
    Explanation
    High barometric pressure is typically associated with clear and stable weather conditions. This is because high pressure systems usually bring sinking air, which inhibits cloud formation and precipitation. As a result, the forecast for an area experiencing high barometric pressure would be sunny.

    The layers of the atmosphere are classified according to what?

    • Altitude

    • Temperature

    • Humidity

    • Air pressure

    Correct Answer
    A. Temperature
    Explanation
    The layers of the atmosphere are classified according to temperature. As you move up in the atmosphere, the temperature changes in different layers. The layers are named based on these temperature variations, such as the troposphere, stratosphere, mesosphere, and thermosphere. Each layer has its own unique characteristics and temperature patterns, which play a significant role in determining the behavior of weather and climate systems.
