GEOLOGY

Detailed explanation-1: -The movement of Earth’s plates causes Earthquake.

Detailed explanation-2: -The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth’s mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years (Fig.

Detailed explanation-3: -Plate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig. 7.14).

Detailed explanation-4: -Divergent boundaries–where new crust is generated as the plates pull away from each other.
