Which of the following characteristics distinguishes objects in the Oort Cloud from objects in the Kuiper Belt?

• Objects in the Oort Cloud are primarily composed of metal and rock, while objects in the Kuiper Belt are made of ice.

• Objects in the Oort Cloud have a much shorter orbital period compared to objects in the Kuiper Belt.

• Objects in the Oort Cloud are much farther from the Sun and have more elliptical orbits compared to objects in the Kuiper Belt.

• Objects in the Oort Cloud are larger and more numerous than those in the Kuiper Belt.

An astronomer is creating a model to show different regions of our solar system. Which TWO statements correctly describe the locations and properties of objects in this model?

• The asteroid belt forms a boundary between the inner and outer solar system.

• The asteroid belt is located between Earth and Mars.

• Most asteroids orbit between Mars and Jupiter.

• The inner solar system extends beyond the asteroid belt.

• The asteroid belt forms a perfect circular orbit around the Sun.

How are asteroids, comets, and meteors related?

• Meteors are small fragments that break from the icy bodies of comets, or the rocky bodies of asteroids orbiting the sun and enter Earth’s atmosphere.

• Asteroids are small fragments that break from the icy bodies of comets or the rocky bodies of meteors orbiting the sun and enter Earth’s atmosphere.

• Comets are small fragments that break from the icy bodies of meteors, or the rocky bodies of asteroids orbiting the sun and enter Earth’s atmosphere.

• Meteors are small fragments that break from the icy bodies of asteroids, or the rocky bodies of comets orbiting the sun and enter Earth’s atmosphere.
