Energy Transfer

Front

What is convection?

Back

Convection is the process of heat transfer that occurs due to density differences in fluids (liquids and gases). Warm fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of Earth's atmosphere, where weather occurs and temperature decreases with altitude.

Front

How does increased carbon dioxide (CO2) concentration affect Earth's atmosphere?

Back

Increased CO2 concentration leads to an increase in the absorption of long-wave heat radiation by Earth's atmosphere, contributing to the greenhouse effect.

Front

What is the primary function of greenhouse glass?

Back

The glass allows short wavelengths of radiation (visible light) to enter while reducing the amount of long wavelength radiation (infrared) that escapes, helping to maintain warmth inside.

Front

What is radiation?

Back

Radiation is the transfer of energy in the form of electromagnetic waves. It does not require a medium to travel through.

Front

What is conduction?

Back

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

Front

What is the difference between conduction and convection?

Back

Conduction transfers heat through direct contact, while convection transfers heat through the movement of fluids caused by density differences.

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.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), and water vapor.

Front

What is insolation?

Back

Insolation refers to the amount of solar radiation received by a given area, typically measured in watts per square meter.
