Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through space.

Front

What is a tropical climate?

Back

A tropical climate is a warm, moist climate zone near the equator, characterized by high temperatures and significant rainfall throughout the year.

Front

What heats the Earth's oceans?

Back

The sun heats the Earth's oceans through radiation, warming the surface water.

Front

What is the definition of convection currents?

Back

Convection currents are the circular patterns of movement in a fluid caused by the rising of warm fluid and the sinking of cooler fluid.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the energy needed for evaporation, which transforms liquid water into water vapor, allowing the water cycle to continue.

Front

What is the difference between conduction and convection?

Back

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

Front

What happens to the density of a fluid when it is heated?

Back

When a fluid is heated, it becomes less dense and tends to rise.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.
