What are tecnonic plate?

Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact with one another on the semi-fluid asthenosphere beneath them. These plates can collide, pull apart, or slide past each other, leading to geological events such as earthquakes, volcanic eruptions, and the formation of mountains. The movement of tectonic plates is driven by forces such as mantle convection, gravity, and slab pull. There are seven major tectonic plates, along with several smaller ones, collectively shaping the Earth's surface over millions of years.
