GEOLOGY

Detailed explanation-1: -Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig.

Detailed explanation-2: -Answer and Explanation: Plate tectonics is responsible for both adding and removing rock material from the Earth’s surface. Plate tectonics accomplishes this via subduction of plate boundaries or the divergence of boundaries.

Detailed explanation-3: -Earthquakes are caused by the movement and interaction of sections of the Earth’s crust and upper mantle. The Earth’s crust is additionally referred to as the Lithosphere and it consists of the many tectonic plates.

Detailed explanation-4: -Most movement occurs along narrow zones between plates, plate boundaries, where the results of plate-tectonic forces are most evident. Atlantic ocean, along a global system of mountain ridges, Earth’s plates are growing and spreading apart.

Detailed explanation-5: -The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
