Earth's Water Quiz 1

What is a wave in the context of oceanography?

• A large stream of moving water that flows through the oceans.

• The movement of energy through a body of water.

• The vertical distance from the crest to the trough.

• A smooth surface of the ocean.

What causes waves to form?

• The smoothness of the ocean surface.

• The distance between the crest and trough.

• Winds blowing across the water.

• The temperature of the water.

What are the two main factors that determine the size of waves?

• The temperature and salinity of the water.

• The distance the wind blows and the smoothness of the ocean.

• The distance the wind blows and the intensity of the wind speed.

• The depth of the ocean and the type of currents.

What is wave height?

• The horizontal distance from crest or trough of one wave to the crest or trough of another.

• The movement of energy through a body of water.

• The vertical distance from the crest to the trough.

What is wavelength in terms of waves?

• The vertical distance from the crest to the trough.

• The movement of energy through a body of water.

• The horizontal distance from crest or trough of one wave to the crest or trough of another.

• A large stream of moving water that flows through the oceans.

What causes ocean currents?

• The intensity of the wind speed.

• The distance the wind blows across the water.

• Wind, temperature, and density differences in salinity.

• The vertical distance from the crest to the trough.

How are currents categorized?

• Crest currents and trough currents.

• Surface currents and deep currents.

• Long currents and short currents.
