Why do most meteors that fall into the earths atmosphere burn up before reaching the ground?

Most meteors burn up in the Earth's atmosphere due to the immense friction generated as they travel at high speeds, often exceeding 25,000 miles per hour. This friction heats the meteor to extreme temperatures, causing it to vaporize before it can reach the surface. The intense heat and pressure create a brilliant streak of light, known as a meteor or "shooting star." Only larger meteoroids, which can withstand this heating, may survive to reach the ground as meteorites.
