Chapter 11 In-Class Review - Astronomy

What is a meteoroid?

• any one of the large rocky bodies that orbit the Sun, primarily between Jupiter and Saturn

• a glowing trail of hot gas and debris heated by friction as an object moves through the atmosphere

• the object that causes a "shooting star," but before it passes through the atmosphere

• a space rock that survives its fall through Earth's atmosphere and reaches the ground

What is the difference between a meteor and a meteoroid?

• A meteorite is a very tiny meteor.

• A meteorite is the pit made on Earth or a planet when a meteor hits.

• A meteorite is the flash of light in the sky. A meteor is the solid body ending up on the ground.

• A meteor is the flash of light in the sky. A meteorite is the solid body ending up on the ground.

• A meteorite comes from a comet. A meteor comes from an asteroid.

Astronomers believe that most of the meteorites come from broken up asteroids and comets, but some of the meteorites are fragments from the Moon or Mars.

• true

• false

Typical asteroids are irregularly shaped. Why is Ceres not so shaped?

• Ceres is near Earth; it was shaped into a sphere by Earth's gravitational force.

• Ceres is shaped like all the other asteroids.

• Ceres is relatively massive; its gravitational force is strong enough to pull its material into a sphere.

• Ceres is near the Sun; the Sun's heat melted Ceres, and it solidified into a sphere.

Asteroids ________.

• can range in size from a few meters to many hundreds of kilometers

• are small bodies, typically the size of a grain of sand or a boulder

• are larger objects, a few hundred kilometers in size, but not quite large enough to be classified as a planet
