The answers here mentioning friction are incorrect. While friction plays a small role it's not responsible for the main heating. When a fast moving object enters the atmosphere the air in front of it is compressed rapidly and can't get out of the way quick enough. When gases are compressed they heat up, this massive pressure wave in front of the object is responsible for the vast majority of heating especially at higher points in the atmosphere.
Gases get hotter when they are under higher pressure. When an object enters the atmosphere, it's generally going so fast that the air in front of it doesn't have time to flow around it, so it compresses. This puts it under greater pressure, and heats it up. It's usually hot enough to burn up whatever is entering the atmosphere, which is why space shuttles needs so much heat shielding to re-enter safely.....:)
