If a 1km asteroid that has broken up into pieces were to hit earths surface, they would probably release a lot of heat too. Considering that an asteroid of 300m size has never been recorded to hit earth in our time, it could be assumed that a lot of heat is released by its impact.

As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height. The thermosphereis the final layer of our atmosphere. It is also the largest layer, extending between altitudes of 53 and 621 miles.
