know about the composition of an igneous rock based on its color?

27.) What in the world? You just found a rock that is full of HOLES! What do you know about the formation of this rock?

Answer 1

I can answer 26 and 27.

26:

Lighter igneous rocks are more granatic meaning they contain more silica.

Darker igneous rocks are more basaltic meaning they contain more iron and magnesium.

27:

A rock full of holes is likely an igneous rock which formed with many gas pockets inside.
