Question

1. which of the following does not describe a characteristic of an asteroid?

many asteroids contain carbon.
some asteroids have a rocky core surrounded by ice.
all asteroids exist in the asteroid belt.
some asteroids have cores of iron and nickel.

Explanation:

Asteroids are small rocky bodies in space. Many asteroids contain carbon (e.g., carbonaceous asteroids). Some asteroids (like C - type asteroids) have a rocky core surrounded by ice. Some asteroids (such as M - type asteroids) have cores of iron and nickel. However, not all asteroids exist in the asteroid belt. There are near - Earth asteroids, Trojan asteroids (which are in the same orbit as a planet but at specific gravitational stable points), etc. So the statement “All asteroids exist in the asteroid belt” is incorrect.

Answer:

C. All asteroids exist in the asteroid belt.
