Final answer:
Tectonic plates are large pieces of Earth's crust that are constantly moving and interacting, causing significant geological phenomena.
Step-by-step explanation:
Tectonic plates are large pieces of Earth's crust that make up the Earth's surface. These plates are constantly moving and interacting, causing earthquakes, volcanic activity, and the formation of mountains. The Earth's lithosphere, which includes the crust and a portion of the upper mantle, is fragmented into several tectonic plates. These plates are like huge puzzle pieces that fit together, and their movement helps shape the Earth's geography over time.
