ESS2.1 and ESS2.2 Review

Front

What are ocean currents?

Back

Ocean currents are large-scale movements of water within the oceans, driven by factors such as wind, temperature differences, and the Earth's rotation. They play a crucial role in regulating climate by distributing heat around the planet.

What causes warm water to rise in the ocean?

Back

Warm water rises because it is less dense than cold water. When water is heated, its molecules move faster and spread apart, making it lighter.

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water, caused by the rotation of the Earth. It causes currents to curve rather than move in a straight line.

How do jet streams affect weather patterns?

Back

Jet streams are fast-flowing air currents in the atmosphere that influence weather patterns by moving air masses. They typically move from west to east in the Northern Hemisphere.

What is density in the context of ocean water?

Back

Density is the mass of water per unit volume. Cold water is denser than warm water, which causes it to sink in the ocean.

What role does evaporation play in ocean currents?

Back

Evaporation removes water from the ocean surface, increasing salinity and density, which can affect the movement of ocean currents.

Front

What is the relationship between temperature and water density?

Back

As water temperature increases, its density decreases. Conversely, cooler water is denser and sinks.

What is the primary driver of ocean currents?

Back

The primary driver of ocean currents is wind, but they are also influenced by the Earth's rotation, temperature, and salinity differences.

How do ocean currents impact global climate?

Back

Ocean currents help regulate global climate by distributing heat from the equator to the poles, affecting weather patterns and temperatures.

What is the difference between surface currents and deep-water currents?

Back

Surface currents are driven by wind and occur in the upper layer of the ocean, while deep-water currents are driven by differences in density and temperature.
