Study the image seen. Which statement best describes the rock shown?

• The grains of this rock are jagged.

• The grains in this rock are tiny.

• This rock has a non-banded pattern.

• The color of this rock is determined by its texture.

Which property of a rock determines its color?

• its grain size

• its method of formation

• its mineral composition

• its coarse-grain content

Which statement describes the relationship between minerals and rocks?

• Minerals and rocks are the same.

• Aggregates of minerals form rocks.

• Minerals determine the texture of a rock.

• Most rocks are made of a single mineral type.

Study the image shown. Which statement best describes the rock?

• The rock has fine grains.

• The grains of the rock are sharp or jagged.

• The rock is banded.

• The bands of the rock run from the top to the bottom.
