The (a) of Earth is contains all the gasses that surround the planet and protects us from deadly solar radiation.
What is the difference between the lithosphere and the asthenosphere that makes up the mantle?
The lithosphere is made of dense solid metal while the asthenosphere is made of liquid molten metal
The lithosphere is a mixture of gases while the asthenosphere is made of solid rock
The lithosphere is molten rock that moves while the asthenosphere is rigid and thin
The lithosphere is made of solid rock while the asthenosphere is hotter, more flexible rock that moves.
