theory of plate tectonics
Magma chambers are produced as a result of this melting and the magma is lower in density than the surrounding rock material. The shifts and movements of these plates shape our landscape including the spectacular mountain ranges valleys and.

. Plate tectonics is the theory that Earths outer shell is divided into large slabs of solid rock called plates that glide over Earths mantle the rocky inner layer above Earths core. History of Plate Tectonics The theory of plate tectonics has largely been developed since 1967 but the history of ideas extend back considerably longer. We live on a layer of Earth known as the lithosphere which is a collection of rigid slabs that are shifting and sliding into each other. Join Tim and Moby on their expedition to explore plate tectonics.
Plate TectonicsThe Unifying Theory of Geology. These slabs are called tectonic plates and fit together like pieces to a puzzle. It begins ascending by melting and fracturing its way through the overlying rock material. The theory of plate tectonics states that the Earths outermost layer is fragmented into a dozen of large small plates that are moving relative to one another on top of the mobile Asthenosphere.
The subducting plate is heated as it is forced deeper into the mantle and at a depth of about 100 miles 150 km the plate begins to melt. Learn and revise about plate tectonics focusing on the Earths structure plate movement and boundaries with BBC Bitesize KS3 Geography.
