    What moves air and thermal energy throughout the troposphere?

    Correct Answer
    convection currents
    Explanation
    Convection currents are responsible for moving air and thermal energy throughout the troposphere. As the Earth's surface gets heated by the sun, the air in contact with it also gets heated and rises due to its lower density. This creates an upward flow of warm air, while cooler air from higher altitudes moves down to replace it. This continuous circulation of air creates convection currents, which play a crucial role in distributing heat and moisture in the atmosphere, influencing weather patterns and climate.

    Explain how a barometer works

    Correct Answer
    measures atmospheric pressure
    Explanation
    A barometer works by measuring atmospheric pressure. Atmospheric pressure is the force exerted by the weight of the air above a certain point. A barometer consists of a long glass tube filled with mercury or a liquid, which is inverted into a dish of mercury. The height of the liquid in the tube changes with the atmospheric pressure. When the pressure is high, the liquid in the tube is pushed down, and when the pressure is low, the liquid rises. By measuring the height of the liquid, the barometer can determine the atmospheric pressure.
