Fall Semester 2025 Review - Part D

The transfer of energy by EM waves is called

• conduction
• convection
• radiation

Do we need greenhouse gases on Earth?

• Yes - they keep the Earth warm
• Yes - they keep all the gases on our planet
• No - they only cause terrible climate change
• No - they only block some of the Sun's rays

The reason that we have seasons on Earth is because the Earth

• is round.

• is tilted.

• has different surfaces that relect and absorb different amounts of the sun.

• farther away from the sun in the winter than in the summer.

When a dark surface gets covered in snow, the albedo is _______ than normal so the temperature is​ ________.

• higher, higher

• lower, lower

• higher, lower

• lower, higher

If incoming energy is less than the outgoing energy, the Earth's temperature will

• increase

• decrease

• stay the same

As the frequency of an electromagnetic wave increases, the amount of energy in that wave...

• increases.
• decreases.
• stays the same.

Interference is a ____________ phenomenon.

• wave

• particle

Which of the following electromagnetic waves do humans sense as heat?

• ultraviolet light

• x-rays

• gamma rays

• infrared rays

The main difference between a radio wave and an x-ray is its
