Which could cause a satellite to descend low enough that it burns up in earth's atmosphere

Orbit decay could cause a satellite to descend low enough to burn up.

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

Sorry can’t u just tryna get points
