Answer:
1. Viscous Drag
2. Slab-Pull Force
3. Ridge-Push Force
Explanation:
The three factors that drive plate motion in the asthenosphere are as follows:
1. Viscous Drag
2. Slab-Pull Force
3. Ridge-Push Force
Asthenosphere is the upper layer of the earth's mantle. This layer lies below the lithosphere at depths between approximately 80 and 200 km below the surface.
LAB refers to the lithosphere–asthenosphere boundary.

<u>There are three main types of reservoirs; valley-dammed reservoirs, bank-side reservoirs, and service reservoirs. Valley-dammed reservoirs are created in valleys between mountains. Usually, there is an existing lake or body of water.</u>
Answer:
Rift valleys are Formed from either from the action of tensional forces in the crust or from the action of compressional forces!
And they move due to the force of gravity!
The block mountain (horst) is left standing higher above the sunken graben!
