Here's a breakdown:
* Lithosphere: This is the rigid outer layer of the Earth, composed of the crust and the uppermost part of the mantle.
* Asthenosphere: Located beneath the lithosphere, the asthenosphere is a semi-molten, viscous layer of the upper mantle. It's not completely liquid, but behaves like a very thick fluid.
* How it carries the crust: The lithosphere, which includes the crust, floats on top of the asthenosphere. The movement of the asthenosphere, driven by convection currents, causes the tectonic plates that make up the lithosphere to move. This movement is responsible for phenomena like earthquakes, volcanoes, and mountain formation.
Think of it like a plate floating on top of a very thick soup. The plate can move around because the soup is flowing beneath it.
