These movements have a significant impact on the lives of people living on the surface.
The crust, mantle, outer core, and inner core are the four main components that make up the earth’s structure. Each layer has its own chemical composition and physical state, and it has the potential to affect life on the planet’s surface. The plates change as a result of movement in the mantle caused by changes in heat from the centre, which can result in earthquakes and volcanic eruptions. These natural disasters alter our environment and, in some cases, pose a danger to people and property.

Earthquakes can be located along a variety of plate boundaries. Volcanoes, on the other hand, are only found at plate boundaries that are both constructive and destructive.
