2025- Atmosphere & Ocean

Front

What causes warm air to rise?

Back

Warm air rises because it's less dense than cold air.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the phenomenon that causes global winds and ocean currents to flow in a curved path instead of a straight path due to the rotation of the Earth.

Front

Why does a breeze blow into the land from the ocean during the day?

Back

A breeze blows into the land from the ocean because warm air rising over land lets cooler air from the ocean blow in.

Front

How is the earth's atmosphere heated?

Back

The earth's atmosphere is heated unevenly.

Front

What causes deep ocean currents?

Back

Differences in density, temperature, and salt content in water cause deep ocean currents.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often described as how heavy something is for its size.

Front

What is the role of temperature in ocean currents?

Back

Temperature affects the density of water, which in turn influences the movement of ocean currents.

Front

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

Back

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

Front

What is the significance of the uneven heating of the Earth?

Back

Uneven heating of the Earth leads to variations in air pressure, which drives wind patterns and ocean currents.

Front

What is the relationship between air pressure and wind?

Back

Wind is caused by differences in air pressure; air moves from areas of high pressure to areas of low pressure.
