How Energy from the Sun Influences Earth

Front

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids or gases). Warm air or liquid rises, while cooler air or liquid sinks, creating a circular motion.

How does a hot air balloon rise?

Back

A hot air balloon rises because convection causes the warmer air inside the balloon to rise in the cooler atmosphere.

Front

What are convection currents?

Back

Convection currents are the circular motions of warm air rising and cool air sinking, which occur in fluids due to differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight traveling through space to reach Earth.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What happens to air temperature during the day?

Back

As the day progresses, energy from the sun warms the atmosphere, causing the temperature to rise.

Front

What is the role of the sun in weather patterns?

Back

The sun's energy drives weather patterns by heating the Earth's surface, causing air movement and the formation of wind and clouds.

Front

What is the difference between conduction and convection?

Back

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

Front

How does the sun influence ocean currents?

Back

The sun heats the surface of the ocean, causing differences in water temperature and density, which drive ocean currents.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.
