The texture of an igneous rock ________.
A)is controlled by the composition of magma
B)determines the color of the rock
C)is caused by leaching
D)records the rock's cooling history

Question

Quizplus · Accepted Answer

The texture of an igneous rock records the rock's cooling history, as it is determined by the speed at which magma cools and solidifies. The composition of magma can influence the minerals present in the rock and thus affect its overall appearance, but it does not directly control the texture. Leaching can occur after the rock has already formed and will not affect its texture during formation. The color of the rock is also influenced by the minerals present but is not directly related to its texture. Therefore, option D is the best choice.
