Currents. Waves, and Tides

Surface currents are formed by

• the moon's gravity

• global winds

• the sun's gravity

• increased water density

The gravitational pull that the moon exerts on Earth is

• greater on solids than liquids

• the main cause of high and low tides

• responsible for longshore currents

• responsible for tsunamis

Streamlike movements of water that occur at or near the surface of the ocean caused by wind are called

• jet currents

• coriolis currents

• surface currents

• deep currents

Which factor affects the movement of deep currents?

• increase in salinity

• the coriolis effect

• continental deflection

• deep currents

Tags

NGSS.MS-ESS2-6

Where do deep currents form?

• where the coriolis effect is strongest

• where the Earth's magnetic field is strongest

• where water's density increase

• where water's density decreases

___________ carry warmer, less dense water from the equatorial regions to polar regions (Ex. Gulf Stream)

• trade currents

• coriolis currents

• surface currents

• deep currents

Deep Atlantic Currents are formed largely as a result of

• erosion by surface winds

• heating of surface water

• the rotation of the Earth

• denser water sinking

• cold with high salinity

• cold with low salinity

• warm with high salinity

• warm with low salinity
