The texture of an igneous rock_______ .
A) determines the color of the rock
B) is caused by leaching

D) is controlled by the composition of magma

Question

Quizplus · Accepted Answer

The texture of an igneous rock reflects its cooling history, specifically the rate of cooling. This can be seen in features such as the size of crystals and the presence of glassy areas. The composition of the magma can influence the texture, but ultimately it is the cooling process that determines the final texture of the rock. The color of the rock is not necessarily related to its texture, and leaching is a separate process that can affect the chemical composition of a rock but not its texture.
