A single reflection, like shouting at the side of a mountain and hearing

Answer:
Continental drift theory describes the long term effect of plate tectonics.
Explanation:
The long term result of plate tectonic movement is the continental drift. The continents of Earth lay on tectonic plates, that are in motion and interaction via plate tectonics. The drift of the Earths continent is an ongoing process evident in the rift valleys and seafloor spreading zones.
The theory that the Earth's continents are dynamic and have drifted relative to each other is known as continental drift which correlates with the theory of plate tectonics.
Every year, the Earth's outer shell plates are displaced by a small amount due to the heat coming from the Earths interior via convection currents.
