An air parcel warms while its water-vapor content stays the same. What happens to its relative humidity?

  1. A

    Relative humidity increases because warm air holds less water vapor.

  2. B

    Relative humidity decreases because warmer air has a higher saturation vapor pressure.

  3. C

    Relative humidity stays constant because the water-vapor content is unchanged.

  4. D

    Relative humidity reaches 100% because the air is warming.

    The temperature at which water vapor begins evaporating from the ground.

  3. C

    The temperature to which air must cool at constant pressure and water-vapor content to become saturated.

Which statements about air masses and their effects are supported? Select all that apply.

  1. A

    Air that remains over an ocean tends to become moist.

  2. B

    Air that forms over land tends to be drier.

  3. C

    Continental polar air is generally warm and humid.

  4. D

    Maritime tropical air is generally warm and humid, and fronts can help force air upward.

Why can rising moist air cool as it moves higher in the atmosphere?

  1. A

    Rising air encounters higher pressure, contracts, and warms.

  2. B

    Rising air retains its volume and temperature until it reaches the ground again.

  3. C

    Rising air encounters lower pressure, expands, and cools.

  4. D

    Rising air loses water vapor immediately because pressure is lower.

Near-ground air cools overnight to its dew point. What may happen?

  1. A

    The air must become completely dry.

  2. B

    Water may condense near the ground as dew or fog.

  3. C

    The air must warm until it is saturated.

  4. D

    All clouds in the area must produce rain.

An air sample warms while its water-vapor content stays constant. What happens to its relative humidity, and why?

  1. A

    Relative humidity increases because the air can hold more water vapor.

  2. B

    Relative humidity decreases because the air's saturation amount increases while its water-vapor content stays the same.

  3. C

    Relative humidity stays the same because water-vapor content is unchanged.

  4. D

    The air becomes saturated as soon as its temperature rises.

An air mass forms and remains over a warm tropical ocean. Which characteristics should it generally have?

  1. A

    It is generally cold and dry because ocean air loses moisture.

  2. B

    It is generally cold and humid because tropical regions cool the air.

  3. C

    It is generally warm and humid because it forms over a warm ocean.

  4. D

    It is generally warm and dry because oceans prevent evaporation.

Near the ground, winds from several directions flow toward the same area, and air begins to rise. Which process best explains this upward motion?

  1. A

    Orographic lifting, because air is crossing high terrain

  2. B

    Convection, because the air is warmed by the Sun

  3. C

    Frontal lifting, because two air masses are meeting

  4. D

    Convergence, because near-surface air flows together and is pushed upward
