Energy in Earth's Atmosphere

Front

What is the atmosphere?

Back

The atmosphere is a layer of gases surrounding the Earth, essential for life as it provides oxygen, protects from harmful solar radiation, and helps regulate temperature.

Front

How does the atmosphere trap heat?

Back

The atmosphere traps heat through the greenhouse effect, where certain gases, like carbon dioxide, absorb and re-radiate infrared radiation, keeping the Earth's surface warm.

Front

What is convection?

Back

Convection is the process of heat transfer in fluids (liquids and gases) where warm, less dense material rises and cooler, denser material sinks, creating a circulation pattern.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the 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 the atmosphere, such as carbon dioxide, methane, and water vapor, that trap heat and contribute to the greenhouse effect.

Front

What is ultraviolet radiation?

Back

Ultraviolet (UV) radiation is a type of electromagnetic radiation from the sun that can cause skin damage and eye damage.

Front

Why is the ozone layer important?

Back

The ozone layer absorbs most of the sun's harmful ultraviolet radiation, protecting living organisms on Earth.

Front

What is conduction?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through space in the form of electromagnetic waves, such as sunlight.

Front

How do oceans affect climate?

Back

Oceans regulate climate by absorbing heat from the sun, distributing it through currents, and influencing weather patterns.
