Final answer:
Earth's crust is made up of tectonic plates, which can be further classified as continental plates and oceanic plates. Their interaction forms the geological features on Earth.
Step-by-step explanation:
The plates that make up earth's crust are known as tectonic plates. These can be split into two types: continental plates and oceanic plates. Tectonic plates comprise the Earth's lithosphere and they are constantly moving due to the heated material underneath them in the Earth's mantle. This is what causes earthquakes and volcanic activities. It's the interaction between these tectonic plates that form the various geological features on Earth's surface.
