Front

What are surface currents in the ocean?

Back

Surface currents are streamlike movements of water that occur at or near the surface of the ocean, primarily caused by wind.

Front

What role does the Sun play in the water cycle?

Back

The Sun provides the energy necessary for evaporation and transpiration, making it essential for the water cycle to occur.

Front

What causes deep Atlantic currents?

Back

Deep Atlantic currents are formed largely as a result of denser water sinking.

Front

During which stage of the water cycle does water flow back towards the sea as runoff?

Back

Water flows back towards the sea as runoff during the runoff stage of the water cycle.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves through the environment, including evaporation, condensation, precipitation, and runoff.

Front

Define evaporation in the context of the water cycle.

Back

Evaporation is the process by which water changes from a liquid to a gas, primarily due to heat from the Sun.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.

Front

Explain the term 'runoff' in the water cycle.

Back

Runoff refers to the flow of water, usually from precipitation, that moves across the land and eventually returns to bodies of water like rivers, lakes, and oceans.

Front

What is the significance of ocean currents?

Back

Ocean currents play a crucial role in regulating climate, distributing heat, and influencing weather patterns around the globe.

Front

How do wind patterns affect ocean currents?

Back

Wind patterns drive surface currents by exerting friction on the water's surface, causing it to move in specific directions.
