OCEAN CURRENTS

Deep Ocean currents are a result of

• Global Wind Patterns

• Earth's Rotation

• differences in water density

• All of the above

The Coriolis Effect is caused by

• Earth rotating around the sun

• Earth rotating on its axis (itself)

• The tides

• Gravity

Where is ocean water the densest?

• The surface

• The middle

• The bottom

• Lake Michigan

When surface currents meet continents they ___?

• top moving

• Are deflected (change paths)

• Continue in the direction they were going

Why are surface currents at the surface of the ocean?

• colder temperature

• colder temperature & more salinity

• warmer temperature & less salinity

• less salinity

The movement of deep, cold, nutrient-filled water to the surface of the ocean is

• Ocean Current

• Upwelling

• Deep Currents

• Surface Currents

Two types of ocean currents are

• local and global

• sea and land

• surface and deep

• warm and cold

Currents that occur at or near the surface of the ocean are called

• Deep Currents

• Convection Currents

• Surface Currents

• Wave Currents

Surface currents are mainly caused by

• The Coriolis Effect

• Cold and Warm Water

• Convection

• Wind

Regular movements of water far below the ocean's surface are called

• Warm Currents

• Deep Currents

• Shallow Currents

• Surface Currents
