If a ball is rolling down a hill, it has both kinetic and potential energy. The ball has 38 J of potential energy because of its height and 80J of kinetic energy because
of its motion. How much mechanical energy does the ball have

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
