Final answer:
Plate tectonics causes continents on Earth to change shape and size.
Step-by-step explanation:
The correct answer is D. The movement of plates causes continents on Earth to change shape and size. This is known as plate tectonics, which is the scientific theory that describes the large-scale movements of Earth's crust. These movements are caused by the interactions between rigid plates that make up Earth's lithosphere. As plates collide, separate, or slide past each other, they create various landforms such as mountains, valleys, and oceanic trenches.
