Unit 2.2 Energy Transfer on Earth Review

Front

What causes convection currents?

Back

Convection currents are caused by warm particles that rise and force cool particles to sink.

Front

What are examples of convection currents?

Back

Examples of convection currents include ocean currents and wind.

Front

What is the most likely cause of a thunderstorm after warm ocean water evaporates?

Back

The most likely cause of a thunderstorm is cold air surrounding the clouds.

Front

What causes the movement of air around the Earth?

Back

The movement of air around the Earth is caused by the uneven heating of the Earth by the Sun.

Front

How does lava cause objects to catch on fire?

Back

Lava causes objects to catch on fire through conduction, transferring thermal energy directly to solid objects.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

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

Front

Explain the role of the Sun in energy transfer on Earth.

Back

The Sun heats the Earth's surface unevenly, leading to temperature differences that drive convection currents and weather patterns.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects (like air and water) caused by the rotation of the Earth.
