• Some moons are covered in craters.

• Some moons have their own ring systems.

• Some moons have a breathable atmosphere.

• Some moons are larger than they planets they orbit.

How is the rotation at the equator of the sun different from the rotation at the poles of the sun?

• The equator rotates more slowly than the poles.

• The equator rotates more rapidly than the poles.

• The equator and the poles rotate at the same speed.

• The equator, North Pole, and South Pole all rotate at different speeds.

The Oort cloud and the Kuiper belt contain many small objects and represent the outer limits of the solar system. Which statements correctly describe these regions of space? Choose FOUR correct answers.

• the source of meteors

• extend beyond the planets of the solar system into outer space

• mostly made of frozen materials, including water

• contains objects that orbit the sun

• includes dwarf planets

Meteors, comets, asteroids, and moons are objects found in our solar system. Each has its own properties, location, and movement. Match the property, location, or movement with the correct celestial object. Write the letter of ONE correct answer in each box.

• located in a band between Mars & Jupiter

• meteors

• located in Earth's atmosphere

• asteroids

• develop a “tail” when near the sun

• comets

• orbit only a single planet

• moons
