Exploring Ocean Circulation

What are the three main movements of ocean water?

• surges, currents, tides

• currents, tides, waves

• streams, floods, whirlpools

• ripples, eddies, swells

What happens to a ball when it falls into the ocean?

• The ball either floats on the surface or sinks to the ocean floor.

• The ball turns into a fish when it hits the ocean.

• The ball disintegrates upon impact with the water.

• The ball bounces back into the air after hitting the surface.

How are waves formed in the ocean?

• Waves are generated by fish swimming near the surface.

• Waves form due to the gravitational pull of the moon.

• Waves are created by underwater volcanic eruptions.

• Waves are formed by the wind transferring energy to the water surface.

What can cause huge waves during a storm?

• Calm seas and clear skies.

• Weak ocean currents.

• Low tide conditions.

• Strong winds and storm intensity.

What is a tsunami?

• A tsunami is a large ship used for ocean travel.

• A tsunami is a type of fish found in the ocean.

• A tsunami is a weather phenomenon that causes heavy rain.

• A tsunami is a series of ocean waves caused by the displacement of water, often due to underwater earthquakes.

How high can a tsunami be?

• Tsunamis can only reach heights of 50 feet (15 meters).

• Tsunamis are typically less than 10 feet (3 meters) high.

• The maximum height of a tsunami is 200 feet (61 meters).

• Tsunamis can reach heights of over 1,700 feet (520 meters) in extreme cases.

What natural events can lead to the formation of a tsunami?

• Tidal waves caused by strong winds

• Earth's rotation affecting ocean currents

• Seasonal flooding from heavy rains

• Underwater earthquakes, volcanic eruptions, landslides, and meteorite impacts.

What is the difference between waves and currents?

• Waves are energy disturbances, while currents are continuous water movements.

• Currents are caused by wind, while waves are not.

• Waves are always larger than currents.

• Waves move in a straight line, while currents swirl around.

How do tides differ from waves?

• Tides and waves are both caused by the same meteorological conditions.

• Tides are caused by wind and occur over shorter periods.

• Tides are caused by gravitational forces and occur over longer periods, while waves are caused by wind and occur over shorter periods.

• Waves are influenced by gravitational forces and occur over longer periods.

What role do winds play in ocean waves?

• Winds have no effect on ocean waves.

• Winds only affect the temperature of ocean water.

• Winds are a minor factor compared to underwater currents.

• Winds are the primary force that generates and shapes ocean waves.
