what is a slab pull A folding and crumpling and sliding upward creating mountains, B currents just beneath earth crust flow very slowly causing movement in the plates above them, C cooler denser crust sinks into the mantle, D when edges become denser and gravity pulls them downward and away from one another

Answer 1

Slab pull is primarily described by C: cooler denser crust sinks into the mantle. In tectonic plate dynamics, when an oceanic plate becomes old and dense, it can begin to sink into the mantle at a subduction zone, pulling the rest of the plate along with it. This process contributes to the movement of tectonic plates and is one of the key driving forces behind plate tectonics.

Other options you provided describe different tectonic processes:

• A refers to processes that can lead to mountain formation, such as orogeny.
• B describes mantle convection, which also contributes to plate movement.
• D describes the concept of slab pull but focuses more on the role of gravity acting on the plates.

So, the best answer specifically for slab pull is C.
