Question

Quizplus · Accepted Answer

The plate tectonic theory assumes that Earth's diameter has been essentially constant over time, allowing for the movement of tectonic plates on the surface without significantly changing the size of the Earth. This assumption is crucial for understanding the dynamics of plate movements and interactions.
