A space rock that does not enter Earth's atmosphere is known as a
A.Meteor
B.Meteoroid
C.Meteorite
D.A black hole
A meteoroid is a small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
The correct answer is B. Meteoroid.
To arrive at this answer, we need to understand the different terms associated with space rocks and their interactions with the Earth's atmosphere.
A meteor refers to a space rock that enters the Earth's atmosphere and vaporizes or burns up due to friction, producing a glowing streak of light in the sky. These are commonly known as shooting stars.
A meteoroid, on the other hand, is a space rock that is smaller than an asteroid and usually ranges in size from a grain of sand to a few meters in diameter. Meteoroids are found in space and are typically remnants from comets or asteroids. When a meteoroid enters the Earth's atmosphere but does not completely vaporize, it is called a meteor.
A meteorite, however, is a meteoroid that survives its passage through the Earth's atmosphere and lands on the Earth's surface. Meteorites can provide valuable scientific information about the composition of space rocks and their origins.
Therefore, a space rock that does not enter Earth's atmosphere is referred to as a meteoroid. So, the correct answer is B. A meteor.
