WebDensity is a measure of how much mass there is in a given volume or amount of space. The density of any substance is calculated by dividing the mass of the matter by the volume of the matter. In Fig. 2.2, volume is represented by boxes and individual particles of matter are represented by colored shapes. Box A has five spheres. Webasthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. crustal generation and destruction
