What happens to the infrared radiation emitted (put out) by the Earth's surface?

• It goes down to the middle of the Earth

• It is absorbed by the atmosphere

• It warms the surface

• It is reflected back to space

Answer explanation

The infrared radiation emitted by the Earth's surface is absorbed by the atmosphere, not reflected back to space or going down to the middle of the Earth. This process helps in warming the surface.

What role does the atmosphere play in keeping the Earth warm?

• It absorbs no radiation

• It reflects the Sun's radiation

• It allows all radiation to pass through

• It absorbs the Sun's radiation and traps the Earth's radiation

Answer explanation

The atmosphere absorbs the Sun's radiation and traps the Earth's radiation, keeping the Earth warm.
