Minerals in Britain
The outer layer of the Earth has the ability to move. Scientists try to map this movement using a range of clues offered by the Earth. Many of the clues are found in the rocks themselves.
The outer layers of the Earth (the crust and upper part of the mantle) are divided into massive portions of rock called tectonic plates. These plates fit together like a jigsaw puzzle.
These plates have the ability to move due to convection currents that exist in the mantle. This movement means that parts of ancient continents that make up the Britain we know today have moved over the surface of the Earth.
