They are moving so fast that when they hit the atmosphere the air can’t move out of the way. Instead, the air gets compressed. When you compress air, it heats up, and when it gets hot enough, it glows. This heat will also transfer into a spacecraft’s heat shield or the asteroid, and bits vaporize off and get blown away.
