The mechanism that moves continents is based on heat energy moving by
Radiation in the core
Conduction in the lithosphere
Convection in the Mantle (Earth's interior)
None of these options is true
What is the difference between the lithosphere and asthenosphere that makes up the mantle?
The lithosphere is ismade of dense solid meal whle the asthenosphere is made of liquid molten metal
The lithosphere is a mixture of gasses while the asthenosphere is made of solid rock
The lithosphere is molten rock that moves while the asthenosphere is ridid and thin
The lithosphere is made of solid rock while the asthenosphere is more flexible hot rock that moves.
