How Plate Tectonics Affects Sedimentation. Earth’s formation can be divided into 3 layers; the outer layer is the solid crust, under which is highly viscous solid mantle which is 6km under the oceans and 30-50 km under the continents. The crust and upper mantel is known as lithosphere, which comprise tectonic plates. Below the lithosphere is the core which has the highest temperature. The heat produced from the centre of the earth causes mantle convection and tectonic plates. Formation of mountain ranges, oceanic trenches and earthquake and volcanic activities occur when these plate boundaries interact with each other. Rocks are combination of minerals. There are three types of rocks: Igneous rocks are made from extreme heat i.e. lava or magma, Sedimentary rocks are formed when small particles of minerals are combined over a long period of time, and Metamorphic rocks are ones who change their forms over a passage of time. Clastic sedimentation occurs when rocks and minerals are weathered or eroded and their particles are then deposited elsewhere. Over a passage of time, pressure and heat harden the particles and turn them into rocks. The clastic sediment usually accumulates in the subduction
