Answer:
The Lithosphere
Step-by-step explanation:
The cool, rigid outermost layer of earth that is divided into enormous pieces called tectonic plates is called the lithosphere. The lithosphere is the solid outermost layer of the earth, and it is composed of rocks and minerals. It is the layer of the earth on which we live and includes the earth's crust and the uppermost part of the mantle. The lithosphere is divided into several large, movable pieces called tectonic plates, which are in constant motion. This motion is responsible for the formation of earthquakes, volcanoes, and other geologic phenomena.
