Heat flow and movement of rock material within Earth are directly responsible for which of the following?

Formation of mountains and ocean basins.

Explanation:

Earth is an active planet. It has multiple layers, and in the second layer from the top a process happens that is crucial for pretty much everything that occurs on the surface. This process is the circulation of convection currents in the mantle. Basically, the cooler and denser material sinks while the hotter and less dense material is pushed up.

This process creates constant pressure on the crust, and it is the one responsible for cracking and creating tectonic plates that move around the globe. With the interaction of the tectonic plates and different types of plate boundaries, there are numerous different processes that happen on the surface, with the formation of mountains and ocean basins being some of them.

e aThe mountains form at places where plates collide. One plate moves below the other so the crust near the plate boundary goes up, gradually forming a mountain range. Ocean basins are formed where hee are divergent plate boundaries on land. The crust splits open as the plates move away, a gap is formed which is constantly widening, and eventually ocean waters fill in the spreading gap. Over the course of tens of millions of years, a new ocean will be formed.
