Ocean Currents Quiz

During a school project, Jackson, Maya, and Lily are studying about ocean currents. They are trying to understand what is the main driving force behind surface ocean currents. Can you help them?

• The gravitational pull of the moon and the sun

• Wind

• Underwater volcanic activity

• The temperature of the water

Mason, Evelyn, and Avery went on a beach vacation. They noticed that their floating toys were drifting away from the shore. Which type of ocean current, caused by the wind, might be responsible for this?

• Surface currents

• Thermal currents

• Tidal currents

• Underwater currents

What are the two main factors that influence deep ocean currents?

• Tides and currents

• Temperature and salinity

• Wind and pressure

• Depth and color

How do deep ocean currents affect the distribution of nutrients in the ocean?

• Deep ocean currents push nutrients deeper into the ocean

• Deep ocean currents cause nutrients to evaporate from the ocean

• Deep ocean currents have no effect on the distribution of nutrients

• Deep ocean currents bring nutrients from the ocean floor to the surface

What is the temperature difference between deep ocean currents and surface ocean currents?

• Surface ocean currents are generally colder than deep ocean currents.

• Deep ocean currents are generally warmer than surface ocean currents.

• Deep ocean currents are generally colder than surface ocean currents.

• There is no temperature difference between deep ocean currents and surface ocean currents.

How do surface ocean currents affect the climate of coastal regions?

• Creating strong winds and storms

• Causing earthquakes and tsunamis

• Affecting the salinity of the water

• Transporting warm or cold water to influence temperature and precipitation patterns

What are the major differences between deep ocean currents and surface ocean currents?

• Density differences and speed

• Temperature and color

• Direction and smell

• Salinity and taste

Explain the role of ocean currents in the transportation of heat around the Earth.

• They only transport cold water from the equator to the poles and warm water from the poles to the equator

• They have no role in the transportation of heat around the Earth

• They redistribute warm water from the equator to the poles and cold water from the poles to the equator.

• They only transport heat within the ocean, not around the Earth

Warm ocean currents generally come from

• The North Pole
• The South Pole
• The Equator
• Both A and B

What is the main energy source that drives ocean movement?

• Earth's core

• the sun

• radioactive rocks on the bottom of the ocean

• fossil fuels
