Detailed explanation-1: -The newly identified molten layer is located 100 miles (161 kilometers) below the Earth’s surface. This layer is a part of the asthenosphere, which sits beneath the tectonic plates. The asthenosphere exists as a soft layer of solid but malleable rock that can cause the tectonic plates to move and shift.
Detailed explanation-2: -These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
Detailed explanation-3: -Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.
Detailed explanation-4: -Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges) Slab pull (gravitational force in subduction zones)
