The crews of two row boats in a river can communicate with each other by shouting. Why is it impossible for the crews of two spaceships a similar distance apart in space to do this?

• The sound travels slower.

• The spaceship soundproofed.

• The spaceships travel too fast.

• Space is a near vacuum and matter is required to transmit sound.

Which of the following best describes a mechanical wave with high energy?

• High period

• High amplitude

• High frequency

• High temperature

How does energy from the sun heat the Earth’s atmosphere?

• Clouds trap the sun’s heat energy in the atmosphere.

• The atmosphere absorbs the sun’s light energy directly and changes it to heat.

• The ground absorbs the sun’s light energy, transforms it to heat energy and releases some of that into the atmosphere.

• The Earth reflects the light energy produced by the sun into the atmosphere where it turns into heat.
