Front

What is the largest ocean basin on Earth?

Back

The Pacific Ocean is the largest ocean basin.

Front

What process does NOT lead to a decrease in the salinity of ocean water?

Back

Evaporation does not lead to a decrease in salinity; it increases salinity.

Front

How does the Coriolis Effect influence water movement in the northern hemisphere?

Back

Due to the Coriolis Effect, water in the northern hemisphere moves in a clockwise direction.

Front

What is the term for the rising of cold water from deeper layers to replace warmer surface water?

Back

Upwelling is the process of cold water rising to replace warmer surface water.

Front

What percentage of Earth's surface is covered by oceans?

Back

Approximately 70% of Earth's surface is covered by oceans.

Front

What is salinity?

Back

Salinity is the measure of the amount of dissolved salts in water.

Front

What is the primary cause of ocean currents?

Back

Ocean currents are primarily caused by wind, the Earth's rotation, and differences in water density.

Front

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

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by density differences and occur below the surface.

Front

What is the role of upwelling in ocean ecosystems?

Back

Upwelling brings nutrient-rich water to the surface, supporting marine life and fisheries.

Front

What is the significance of the thermohaline circulation?

Back

Thermohaline circulation is crucial for regulating climate and distributing heat across the planet.
