What would happen if you didn't have the asthenosphere?

Answer 1

well first all our air would be gone. if you were lucky and didn't need air, then the sun's UV radiation would cause some nasty damage. you also would die from the lack of pressure as if you fell out into space. most of the stuff on earth could get sucked out into the vacuum of space (including you), and if the magnetic field went too then the sun would just fry us all. all in all, losing an atmosphere is a bad idea.
