Tectonic plate
A tectonic plate is a large, rigid slab of the Earth's lithosphere that moves relative to other plates, shaping the planet's surface through processes such as plate tectonics. The Earth's surface is divided into several major and minor tectonic plates, which are in constant motion, sometimes sliding past each other, and other times colliding or moving apart. This movement is responsible for the formation of Mountain ranges, volcanoes, and earthquakes. The study of tectonic plates is crucial for understanding the Earth's geology and hydrologic cycle. Astrobiologists also study tectonic plates to better understand the potential for life on other planets. The movement of tectonic plates is driven by Convection currents in the Earth's Mantle, which is composed of hot, viscous Rock.
