* Color: While color can be influenced by mineral composition, it's not a defining characteristic of rock texture. Two rocks can have the same texture but different colors.

* Shape: The overall shape of a rock (e.g., rounded, angular) is not considered texture.

* Size: The size of a rock is not texture.

* Mineral Composition: The specific types of minerals present in a rock are related to its composition, not its texture.

* Weathering: The way a rock has been eroded or altered by the elements is not part of its original texture.

* Fossil content: The presence of fossils is interesting, but not directly related to the rock's texture.

Key takeaway: Texture refers to the arrangement, size, and shape of mineral grains within a rock. It describes the "look and feel" of the rock at a microscopic level.
