Based on the weathering patterns you see,what rock type is most likely shown below?
Musya8 [376]

The correct answer is - limestone.

On the image, it seems that we have a representation of rock formations in a cave. They are evidently weathering. According to the manifestation of the weathering, the color of the rocks, and that it is most probably a cave, the chances are mostly likely that it is a limestone.

The weathering appears as a result of the water. The limestone is a sedimentary type of rock, thus it doesn't have strong structure. The water is able to gradually penetrate through it, making holes in it, and little by little weather it. In this way we have the formation of the water reservoirs, springs, cave systems.
