GEOLOGY

Detailed explanation-1: -A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust. A well-tested concept that explains a wide range of observations. The theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.

Detailed explanation-2: -Answer and Explanation: The upper section of the lithosphere carries the crust of the Earth. The lithosphere is made of two parts: the crust and the upper part of the mantle. The crust is made of both the continental crust, or land, and oceanic crust, or ocean bottom.

Detailed explanation-3: -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-4: -The perpetual “slip ‘n’ slide” motion of the lithosphere on the asthenosphere caused it to fragment into several large sections called tectonic plates.

Detailed explanation-5: -Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth’s tectonic plates and allowing them to move.
