Detailed explanation-1: -The lithosphere is the solid, outer part of Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure.

Detailed explanation-2: -The Geosphere is associated with solid portions of the Earth. It includes the continental and oceanic crust and all other layers of the Earth’s interior. This includes all rocks, sediments and soils, surface landforms and the processes that shape the Earth’s surface.

Detailed explanation-3: -Plate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig.

Detailed explanation-4: -Tectonic Plates 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). The plates act like a hard and rigid shell compared to Earth’s mantle.
