Given the question: Q: What causes a meteoroid to vaporize after it enters the atmosphere? Read this paragraph and choose the correct option from the provided answers: A meteoroid is dragged toward Earth by gravity and enters the atmosphere. Friction with the atmosphere heats the object quickly, so it starts to vaporize. As it flies through the atmosphere, it leaves a trail of glowing gases. The object is now a meteor. Most meteors vaporize in the atmosphere. They never reach Earth's surface. Large meteoroids may not burn up entirely in the atmosphere. A small core may remain and hit Earth's surface. This is called a meteorite . Choices: - gravitational pull - atmospheric pressure - spontaneous combustion - friction with atmosphere A:
The answer is:
friction with atmosphere
