GEOLOGY

Detailed explanation-1: -Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.

Detailed explanation-2: -The Earth’s crust is broken up into pieces called plates. These plates move due to convection currents in the mantle . Heat from the core makes magma in the mantle rise towards the crust. As the hot current nears the crust, it begins to cool and sink back towards the core.

Detailed explanation-3: -Tectonic plates, the massive slabs of Earth’s lithosphere that help define our continents and ocean, are constantly on the move. Plate tectonics is driven by a variety of forces: dynamic movement in the mantle, dense oceanic crust interacting with the ductile asthenosphere, even the rotation of the planet.

Detailed explanation-4: -The tectonic plates move due to convection currents in the upper mantle. They float on the semi-fluid layer of rock in the upper mantle called the asthenosphere. This layer is around 50 to 120 miles below the Earth’s surface. Liquid rock under the Earth’s surface, or magma, moves in convection currents.
