GEOLOGY

Detailed explanation-1: -The crust and the upper part of the mantle is called the lithosphere. It is rather like a jigsaw puzzle and is made up of large pieces called tectonic plates.

Detailed explanation-2: -Of about 50 plates, a mere seven account for 94 percent of the surface. The biggest, the Africa and the Pacific plates, are antipodal, meaning they sit on opposite sides of the Earth. But about 100 million years ago, the tectonic plates tiled the planet as evenly as a real-life jigsaw puzzle.

Detailed explanation-3: -Plate Tectonics The lithosphere is divided into tectonic plates including the North American, Caribbean, South American, Scotia, Antarctic, Eurasian, Arabian, African, Indian, Philippine, Australian, Pacific, Juan de Fuca, Cocos, and Nazca.

Detailed explanation-4: -The lithosphere is the surface layer of the fluid parts of the Earth’s convection system, therefore it thickens over time. It is broken up into pieces called plates (shown in the picture on the left), which move independently relative to one another. This movement of lithospheric plates is described as plate tectonics.
