What is a rock with large crystals scattered on a background of much smaller crystals?
what is Porphyritic Texture
How do geologists look at mineral composition?
what is Geologists look at a small sliver rock under a microscope so they can observe the shape and size of crystals in the rock

What is a Sedimentary rock.
How are clastic rocks formed?
What is when a sedimentary rock that forms when rock fragments are squeezed together.
What happens when a metamorphic rock when it is nonfoliated?
what is It is nonfoliated when there is not split into layers
What are most igneous rocks?
what is Hard, dense, and durable
Why do some rocks have no grain?
what is when they form, they cool very quickly which causes the rock to become smooth, shiny, texture forms into a piece of glass.
