High silica content means the rock will have what type of color

• dark

• light

• blue

• green

uses the size, shape and pattern of the grains

• texture

• origin

• course

• fine

can see the crystals or the parts of the rock

• course grained

• fine grained

can't see the grains with your eyes, only with a microscope

• course grained

• fine grained

how the rock is formed

• texture

• origin

• birth story

• intrusive igneous

• extrusive igneous
