GEOLOGY

Detailed explanation-1: -Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes.

Detailed explanation-2: -Tectonic plates, large slabs of rock that divide Earth’s crust, move constantly to reshape the Earth’s landscape. 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-3: -The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.

Detailed explanation-4: -Earth’s Crust. “Crust” describes the outermost shell of a terrestrial planet. Earth’s crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth’s crust is informed by plate tectonics.

Detailed explanation-5: -They are floating on Earth’s mantle, a really thick layer of hot flowing rock. Even though plates move very slowly, their motion, called plate tectonics, has a huge impact on our planet. Plate tectonics form the oceans, continents, and mountains.
