Ocean Currents FY25

Front

What is convection?

Back

Convection is the circulation of hot and cold fluids (liquids and gases) due to differences in temperature and density.

Front

Where do warm ocean currents generally come from?

Back

Warm ocean currents generally come from the Equator.

Front

What is the 'Global Conveyor Belt'?

Back

The 'Global Conveyor Belt' refers to the large-scale movement of ocean currents that circulate warm and cold water around the globe, influencing climate and weather patterns.

Front

Which type of water would sink the fastest?

Back

Cold and salty water would sink the fastest due to its higher density.

Front

What is the primary driver of ocean currents?

Back

The primary driver of ocean currents is the wind, along with factors like temperature, salinity, and the Earth's rotation.

Front

What role does temperature play in ocean currents?

Back

Temperature affects the density of water; warmer water is less dense and tends to rise, while colder water is denser and sinks.

Front

What is salinity?

Back

Salinity is the concentration of salt in water, which affects its density and the movement of ocean currents.

Front

How do ocean currents affect climate?

Back

Ocean currents help regulate climate by distributing heat around the planet, influencing weather patterns and temperatures.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, often supporting rich marine ecosystems.

Front

What is downwelling?

Back

Downwelling is the process where surface water sinks, often occurring in areas where water is cooled or becomes denser.
