If the bits are small enough, won't they burn up in the atmosphere?



That's not necessarily a better solution since depending on the amount of
debris you're converting the kinetic energy of the asteroid into thermal
energy which heats up the atmosphere and the ground below.

That said, diversion is generally preferred.
