• Ocean Current

• Surface Current

• Deep Current

• Convection Current

This is a stream-like movement of ocean water far beneath the surface of the ocean.

• Ocean Current

• Surface Current

• Convection Current

• Deep Current

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

• Ocean Current

• Upwelling

• Deep Currents

• Surface Currents

Which of the following does not affect surface currents?

• Continental Deflections

• The Coriolis Effect

• Global Winds

• Marine Life

Continents affect surface currents by:

• Dropping Pieces of Rock into the Ocean

• The Coriolis Effect

• Making the Water Warmer

• Continental Deflection

Why is upwelling important?

• Upwelling regulates ocean temperature

• Upwelling provides nutrient rich water that sustains life

• Upwelling controls the tides

• Upwelling helps sailors to navigate the seas

The Coriolis Effect causes..

• Objects to curve over long distances.

• Objects to travel in a straight line.

• Gravity.

• Warm weather at the equator.
