Question

How does Plate Tectonics impact The Rock Cycle?Please use Convection Currents in your explanation. (4-6 sentences)

Answer 1

Answer:

At diverging plate boundaries, convection currents bring hot magma to the surface. This hot magma flows out onto the ocean floor, forming extrusive, finely grained igneous rocks. At convergent plate boundaries, sedimentary rock from the ocean floor gets pushed down into the mantle.

Answer 2

Tectonic process leads to the formation of new plate and these breaks and form primary rocks that further leads to secondary rocks.

Explanation:

• The plate tectonics are rigid slabs of rocks that move on the surface of the earth and are fueled by the heats coming from the mantel and that leads to the formation of rocks such as igneous, metamorphic, and sedimentary.  

• Due to the effects of the earth's core and mantel, the convection currents that rise from deep within these zones gives rise to warm and molten rocks influenced by the mechanical process of diffusion and advection.  

• The sediment that is found in the ocean water is pushed to the continent crust and as the older rocks rushed back towards the continental plates they upon melting convert into igneous rocks and these can be found in volcanic edges and the subduction zones.  

• The sedimentary rocks upon weathering and erosion lead to the formation of sediments and under pressure and heat can lead to the formation of metamorphic rocks.

• The sedimentary rocks can again form metamorphic rocks by compaction and melt to form igneous rocks.
