Which factors influence surface currents?

Wave height, Moon phase, Iceberg presence

Wind, Earth rotation, Shape of continents (correct)

Salinity, Deep water pressure, Ocean depth

Temperature, Soil Composition, Sunlight

What effect does the rotation of the Earth have on currents?

It causes air density to increase.

It deflects winds and currents based on their location relative to the equator. (correct)

It prevents surface currents from forming.

It causes currents to flow faster in the Northern Hemisphere.

What is the primary reason deep water currents are influenced?

Waves and tides

Water temperature and salinity (correct)

Wind speed and direction

Earth's rotation and continental shapes

What happens to waves as they approach the shoreline?

The wavelength decreases and wave height increases. Signup and view all the answers
