A "shooting star" is usually a grain of sand from outer space that burns up and gives off light as it enters the atmosphere. what exactly causes this burning?

it is the friction or drag force on the solid. the object goes so fast that the friction is producing alot of heat. this heat causes it ignite (anything can be burnt if it is heated to high enough tempurature)

friction and drag force causes this burning

The reason behind the burning is drag or friction force.

A "shooting star" is usually a grain of sand from outer space that burns up and gives off light as it enters the atmosphere.

The atmosphere is made up of air which resists the motion of any object by a force known as drag force,

Drag force is nothing but a type of friction force that resists motion.

Now, the drag will create a lot of heat because the shooting star moves with a very fast velocity. This heat will cause the star to burn and produce light.

Therefore, the reason behind the burning is drag or friction force.
