What is a Land Breeze?

Back

A Land Breeze is a type of breeze that occurs at night when cooler air from the land moves towards the sea, replacing the warmer air over the water.

What happens to warm air in convection?

Back

In convection, warm air rises because it is less dense than cooler air.

What is the primary process responsible for heat transfer in the mantle?

Back

Convection is the primary process responsible for heat transfer in the mantle, where hot material rises and cooler material sinks.

Front

What is the initial source of energy that creates winds?

Back

The sun is the initial source of energy that creates winds by heating the Earth's surface.

Why does warm air rise near the ceiling of a room?

Back

Warm air rises near the ceiling of a room due to convection, as it is less dense than the cooler air below.

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

What is a Sea Breeze?

Back

A Sea Breeze is a type of breeze that occurs during the day when cooler air from the sea moves towards the land, replacing the warmer air over the land.

What role does density play in convection currents?

Back

Density differences in fluids cause convection currents; warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids.

Front

What is Radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight warming the Earth.
