Texture is the feel of the world with our eyes and physical touch. The first picture you can see with you eyes it has the circular ridges and can feel those ridges with you mind. Also if you could touch it it has those circular ridges and is a rubber material. The second picture is that school table feel, plastic and rubber with those diamond holes. The third and fifth picture correlate together that tree bark tree wood feel we all are used to feeling playing outside, without touching it you can imagine that feeling of the tree bark. The fourth picture is rough and grainy. You can see the roughness and imagine the feeling and when you actually touch it, it is the rough grainy texture you would think.
