Friction makes meteors burn up

-

Most meteors are converted into dust on their way down Earth’s atmosphere, but it is not the air particles’ friction against the meteors that heat the rocks and make them fall apart.

The heat is generated in the air in front of the meteor, where the air molecules are extremely compressed, and the high pressure makes the temperatur­e rise, so the air catches fire. The heat affects the meteor’s surface and starts to consume the rock, until it is finally gone.

 ??  ?? Cold centre Pressure generates heat.Burning air does not touch meteorThe meteor compresses air in front of it, and the high pressure heats the air to 1,500+ degrees. The hot air is not in direct contact with the rock, but it still heats it. Pocket Heat with cooler air heats the meteor's surface.
