A meteoroid that enters the Earth's atmosphere is called a meteor and a shooting star.
The correct term for a meteoroid if it enters the Earth's atmosphere is a meteor.
To determine the correct term for a meteoroid that enters the Earth's atmosphere, we can break down the options provided and analyze them:
1. A star: A star refers to a luminous celestial object made up of hot gases, such as our Sun. Stars are vastly larger than meteoroids and do not enter the Earth's atmosphere. Therefore, this option is incorrect.
2. A comet: Comets are icy bodies consisting of dust, rock, and frozen gases. When a comet enters the Earth's atmosphere, it typically vaporizes due to the heat and creates a glowing tail. However, the term specifically used for a small object entering the atmosphere is not "comet." Thus, this option is also incorrect.
3. A meteor: This term is the correct answer. When a meteoroid enters the Earth's atmosphere, it becomes a meteor. Meteors are also known as "shooting stars" and can be visible as bright streaks of light in the night sky.
4. A moon: A moon is a natural satellite that orbits around a planet, such as Earth's Moon. Moon-like objects do not enter the Earth's atmosphere. Therefore, this option is incorrect.
Based on the explanation provided, the correct answers are:
- A meteor (1 point)
- None of the given options apply for the second answer since none of the options mentioned are correct (0 points)
Thus, the answer would be "A meteor."
