GEOLOGY

Detailed explanation-1: -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-2: -The lithosphere is broken into separate sections called plates. The geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion, driven by convection currents in the mantle is plate tectonics.

Detailed explanation-3: -The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust.

Detailed explanation-4: -Earth’s hard surface (the lithosphere) can be thought of as a skin that rests and slides upon a semi-molten layer of rock called the asthenosphere. The skin has been broken into many different plates because of differences in the density of the rock and differences in subsurface heating between one region and the next.
