HELP I WILL GIVE THE BRAINLIEST IF CORRECT How does Earth’s asthenosphere contribute to movement of the plates? If the asthenosphere were removed, would these movements be possible? Why?

Pressure on the asthenosphere may also be reduced in zones of divergence, where two plates are separating from each other. ... During this movement of plates, material of the downgoing plate is heated in the asthenosphere, melting occurs, and molten materials flow upward to Earth's surface.

I hope this helps u! :D
