Students live in a town near the beach. They notice that it is often foggy in the mornings during the summer. They also notice that the fog usually starts over the ocean. The students want to play in the Sun at the beach and wonder why the fog always comes from over the ocean.

One student claims that the fog is related to the temperature of the land and the ocean. The student makes a model to explain the formation and movement of the fog.

Which processes cause the fog to form over the ocean and move toward the land? Move one process into each box to complete the model.

Fog-forming processes

Air movement processes

Fog moves toward the land.

Air mass 2

Ocean

Air mass 1

Town

Air mass 1 warms.

Warm air rises.

Ocean absorbs heat from Air Mass 2.

Air mass 2 flows toward the land.

Water condenses into fog above Air Mass 2.

1 answer

To complete the model with the correct processes, you would organize them as follows:

Fog-forming processes:

  1. Ocean absorbs heat from Air Mass 2.
  2. Water condenses into fog above Air Mass 2.

Air movement processes:

  1. Air mass 1 warms.
  2. Warm air rises.
  3. Air mass 2 flows toward the land.

So, the completed model would look like this:

Fog-forming processes

  • Ocean absorbs heat from Air Mass 2.
  • Water condenses into fog above Air Mass 2.

Air movement processes

  • Air mass 1 warms.
  • Warm air rises.
  • Air mass 2 flows toward the land.

This model illustrates how the warming of the land causes air mass 1 to rise, leading to the movement of cooler, moist air (Air Mass 2) from the ocean toward the land, where it absorbs heat and condenses into fog.
