GEOLOGY

Detailed explanation-1: -The system of ideas behind plate tectonics theory suggests that Earth’s outer shell (lithosphere) is divided into several plates that glide over the Earth’s rocky inner layer above the soft core (mantle).

Detailed explanation-2: -Divergent plate boundaries: the two plates move away from each other. Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other.

Detailed explanation-3: -Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.

Detailed explanation-4: -plate tectonics – the theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle. divergent boundary – a plate boundary where two plates move away from each other.

Detailed explanation-5: -Plate tectonics is the theory that Earth’s outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like hard and rigid shells compared to Earth’s mantle. This strong outer layer is called the lithosphere.
