Ocean Currents and Waves Quiz

What are the three main types of ocean currents?

• Northern currents, Southern currents, and Equatorial currents

• Surface currents, deep water currents, and tidal currents

• Warm currents, cold currents, and neutral currents

• Fast currents, slow currents, and medium currents

Explain the difference between surface currents and deep ocean currents.

• Surface currents are influenced by tides and occur in the top 300 meters of the ocean, while deep ocean currents are influenced by storms and occur below 300 meters.

• Surface currents are caused by earthquakes and occur in the top 500 meters of the ocean, while deep ocean currents are caused by volcanic eruptions and occur below 500 meters.

• Surface currents are driven by the moon and occur in the top 100 meters of the ocean, while deep ocean currents are driven by the sun and occur below 100 meters.

• Surface currents are driven by wind and occur in the top 400 meters of the ocean, while deep ocean currents are driven by density and occur below 400 meters.

How do warm ocean currents affect the climate of coastal areas?

• Warm ocean currents bring warm water and air to coastal areas, resulting in a milder climate.

• Warm ocean currents bring cold water and air to coastal areas, resulting in a colder climate.

• Warm ocean currents have no effect on the climate of coastal areas.

• Warm ocean currents bring heavy rainfall to coastal areas, resulting in a wetter climate.

What are the primary causes of ocean currents?

• Moon phases, tides, and earthquakes

• Fish migration, underwater volcanoes, and pollution

• Wind, temperature, and salinity differences

• Boat traffic, coral reefs, and underwater plants

Describe the Coriolis effect and its role in the formation of ocean currents.

• It causes ocean currents to flow faster

• It causes ocean currents to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• It causes ocean currents to flow in a straight line

• It has no effect on the formation of ocean currents

How does the uneven heating of the Earth's surface contribute to the formation of waves?

• Uneven heating of the Earth's surface creates temperature differences, which in turn create pressure differences. These pressure differences contribute to the formation of hurricanes, which generate waves on the ocean's surface.

• Uneven heating of the Earth's surface creates temperature differences, which in turn create pressure differences. These pressure differences contribute to the formation of clouds, which generate waves on the ocean's surface.

• Uneven heating of the Earth's surface creates temperature differences, which in turn create pressure differences. These pressure differences contribute to the formation of earthquakes, which generate waves on the ocean's surface.

• Uneven heating of the Earth's surface creates temperature differences, which in turn create pressure differences. These pressure differences contribute to the formation of wind, which generates waves on the ocean's surface.

What are wind waves and how are they formed?

• Waves created by the movement of tectonic plates

• Waves formed by the gravitational pull of the moon

• Underwater waves caused by seismic activity

• Surface waves formed by the friction between the wind and the surface of the water.

Explain the difference between constructive and destructive waves.

• Constructive waves build up the beach by depositing sand and pebbles, while destructive waves erode the beach by removing sand and pebbles.

• Constructive waves occur during storms, while destructive waves occur during calm weather.

• Constructive waves have a negative impact on the beach, while destructive waves have a positive impact.

• Constructive waves erode the beach by removing sand and pebbles, while destructive waves build up the beach by depositing sand and pebbles.

What are the two main types of waves based on their formation?

• Light waves and X-rays

• Wind-generated waves and tides

• Sound waves and seismic waves

• Radio waves and microwave

From the rest to the crest is a waves?

• trough

• wavelength

• frequency

• amplitude
