Answer:
The rocks may have different textures
Explanation:
If we have to igneous rocks, and they have the same minerals, that doesn't necessarily means that they will have the same name, thus being classified as the same rock. The reason for this is that the two igneous rocks may have a different texture. One of the rocks may have a foliated, while the other may have porphyritic, giving them different appearance despite the same minerals being in both of them. The reason why two igneous rocks with the same minerlas may appear different, is the process in which they have been formed, the quickness of the cooling, the temperature that they were exposed to, and the pressure they were exposed to.
Answer:
A) Power plant
Explanation:
The key to understanding this question, is first knowing what "stationary" means. When something is stationary, it doesn't move, it just stays in one place.
Since power plants are buildings, they naturally don't move. On the other hand, the other choices are all vehicles that are intended to move. So while all of these options do cause air pollution, the power plant is the only one that is stationary.
I hope this answer helps you :)
