##color(darkorange)”The asthenosphere”## is a layer (zone) of Earth’s mantle lying beneath the lithosphere.
It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid.
The rocks are also less dense than the rocks in the lithosphere
It is believed to be much hotter and more fluid than the lithospher
Asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface
