What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

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 empty space.

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with longer wavelengths than visible light. It is emitted by warm objects and is felt as heat.

What is Earth's energy budget?

Back

Earth's energy budget is the balance between the energy Earth receives from the Sun and the energy it radiates back into space. It determines the planet's climate and temperature.

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space. This helps to keep the planet warm.

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind, hydro), while non-renewable energy sources are finite and will eventually run out (e.g., coal, oil, natural gas).

Front

What is the role of the Sun in Earth's energy system?

Back

The Sun provides the primary source of energy for Earth, driving weather patterns, photosynthesis in plants, and the overall climate system.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

Front

What is the significance of the ozone layer?

Back

The ozone layer is a region of Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet radiation, protecting living organisms on the planet.
