Energy Transfer

Front

What is energy transfer?

Back

The process of energy moving from one place or object to another, often occurring in the form of heat, light, or sound.

Front

What are the three main methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials, where energy is passed from one molecule to another.

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in density.

Front

Define radiation.

Back

The transfer of energy through electromagnetic waves, which can occur in a vacuum.

Front

What is insolation?

Back

Insolation refers to the amount of solar radiation energy received on a given surface area during a given time.

Front

What is terrestrial radiation?

Back

The re-radiated infrared energy emitted by the Earth's surface after absorbing solar energy.

Front

How does color affect heat absorption?

Back

Darker colors absorb more heat and radiation than lighter colors, which reflect more light.

Front

What is the greenhouse effect?

Back

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

Front

What role does the atmosphere play in energy transfer?

Back

The atmosphere absorbs, reflects, and transmits solar energy, influencing temperature and weather patterns.
