Ice free areas of antarctica where no rain has fallen for all of recorded history

The reason as to why there are ice free areas of antarctica where no rain has fallen for all recorded history is that extremely dry winds experienced in this part of the antarctica region cause any snow or rainfall blown here to evaporate before hitting the ground.

Explanation:

Therefore, there is snow and ice that travels to this areas but unfortunately, the dry wind does not let them touch the ground.

This gives us the reason as to why there has never been rain touching the ground.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
