Question

Explain the moment of tectonic plates briefly

Answer 1

Tectonic plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down

Answer 2

Movement of tectonic plates :-

The structure of the Earth is layered. The 3 layers of the earth are the crust, mantle and core. The crust is the outermost layer mantle is the middle layer and the core is the innermost layer. Crust is mostly solid mantel is solid due to high pressure. But, inner layers are in a molten state. The outer core is molten but the inner core is solid. The Crust and the upper layer of the mantle are together called the lithosphere.

During an earthquake there is a sudden movement or a fracture in the lithosphere. The lithosphere is not one continuous piece but is divided into numerous small pieces called the plates. These plates keep moving slowly inside the earth. Though, the moments are small the magnitudes of energy developed as a result of this movement is quite large.

Sometimes, the moment causes the ages of tectonic plates to grind each other forcefully resulting in their displacement, deformation, crushing or facture. Due to this changes there are tremors or vibrations in the lithosphere leading to an earthquake. The Earth is divided into seven technique plates and various small plates.
