Waves and Currents

What is a wave?

• A rhythmic movement that carries energy through matter and space.

• A disturbance in the ocean caused by the wind.

• A high-speed movement of ocean water towards the shore.

• A circular motion of water particles in the sea.

On what does the height of a wave depend?

• The temperature of the water

• The speed of the wind

• The depth of the water

• The salinity of the water

What happens to waves once they are set in motion?

• They immediately stop when the wind stops.

• They continue moving for long distances, even if the wind stops blowing.

• They can only move short distances before dissipating.

• They reverse direction and head back out to sea.

How do surface currents move water?

• Vertically – perpendicular to Earth's surface

• Horizontally – parallel to Earth's surface

• In a stationary pattern

• Only downward towards the ocean floor

What is the effect of surface currents on climate?

• They have no effect on climate.

• They only affect the climate locally.

• They affect the climate by transporting heat energy around the world.

• They cool down the climate globally.
