Earth's structure consists of four layers: crust, mantle, outer core, and inner core.
Plate tectonics theory explains that Earth's crust is divided into tectonic plates which move over the mantle.
Tectonic plates interact at their boundaries, causing seismic activity, volcanoes, and the formation of landforms.
There are three types of tectonic plates: major, minor, and microplates, based on their size.
