Asthenosphere refers to the mechanically weak, highly viscous, and ductility deforming segment of the upper mantle of the Earth. It is situated below the lithosphere, at the depths between about 80 and 200 km underneath the surface.
It is characterized by the conditions of higher temperature and pressure, which makes the rock ductile. The crust comprises the rocky surface area, which is made up of silicon, oxygen, aluminum, calcium, iron, potassium, sodium, and magnesium. On the other hand, due to high pressure and temperature in the asthenosphere, the rock appears in a molten state.
Hence, the correct answer is pressure is high than the crust.
