Texture
Texture explained in an easy to understand way:
Imagine trying to fit all your groceries into a single reusable bag after a big shopping trip. Just as you have to consider the size and shape of each item to make everything fit efficiently, geologists examine the size, shape, and arrangement of grains in a rock to understand its texture. In this analogy, each grocery item represents a grain in the rock: the size of the item is like the size of the grain, the shape of the item corresponds to the shape of the grain, and how the items are arranged in the bag is akin to how the grains are packed together in the rock.
Practice Version
Texture: The size, shape, and grains of a rock. Texture. Texture is the feel or appearance of a surface, determined by the size and arrangement of its particles.
