An air mass moves from its source region over a different type of surface. What is a reasonable conclusion?

  1. A

    Its temperature and moisture are guaranteed to remain unchanged.

  2. B

    It must immediately become a different named air-mass type.

  3. C

    Its temperature or moisture properties may change.

  4. D

    It can change only if it crosses a front.

A warm front is approaching a location. Which sequence of conditions is most consistent with its typical passage?

  1. A

    A narrow band of thunderstorms followed by cooler air

  2. B

    Persistent clouds near a boundary where neither air mass advances

On a weather map, isobars are much closer together in one region than elsewhere. What can you reasonably infer?

  1. A

    The pressure is identical everywhere in the region.

  2. B

    Pressure changes more strongly over a short distance, and winds are often stronger.

  3. C

    A front must be stationary.

  4. D

    The region must have a high-pressure system.

    Air tends to converge toward a surface low and rise.

  2. B

    Winds circulate counterclockwise around a Northern Hemisphere surface low.

  3. C

    Air tends to sink over the center of a surface low.

  4. D

    Air generally sinks over the center of an anticyclone.

When interpreting a front symbol on a weather map, what does the symbol indicate?

  1. A

    They guarantee the exact precipitation at every location along the boundary.

  2. B

    They identify only the temperature of the air behind the boundary.

  3. C

    They show the boundary between air masses and its direction of movement.

  4. D

    They indicate that the boundary cannot move.

    mT

  2. B

Air is lifted along a boundary between contrasting air masses. Which process can lead from that lifting to cloud formation?

  1. A

    Rising air compresses and warms, preventing condensation.

  2. B

    Air sinks beneath the boundary and warms until precipitation forms.

  3. C

    Rising air expands and cools, which can allow water vapor to condense.

  4. D

    Earth’s rotation directly turns water vapor into precipitation.

A boundary remains in place because neither air mass advances decisively. What weather pattern can result near that boundary?

  1. A

    Clouds and precipitation may persist near the boundary.

  2. B

    The boundary must move quickly, so precipitation ends immediately.

  3. C

    The warm air is always lifted completely away from the surface.

  4. D

    The air masses mix instantly, preventing clouds from forming.
