D. The Colorado River flows through the Grand Canyon.



Answer :

Final answer:

The incorrect statement is about a type of rock that cools quickly, not slowly.


Explanation:

c. An aphanitic rock cooled very slowly is the statement that is not true.

An aphanitic rock is formed from volcanic lava that cools quickly at or near the Earth's surface, resulting in fine-grained texture. This process does not involve slow cooling, making this statement incorrect.
