OPEN-RESPONSE QUESTIONS

11. Describe how an igneous rock might change into a sedimentary rock.

12. A student on a hike found a mineral he wanted to identify. Describe two tests that he could do to identify the mineral. Be sure to include what he needs to look for when he does each test.

ANSWERS

Key Points

• Igneous rock forms when magma (melted rock) either flows out of a volcano or cools and hardens under Earth’s surface.

• When the rock is exposed to weathering, the rock breaks down into pieces.

• Rock pieces are transported to other places by wind, water, or ice. • Eventually the rock pieces might end up as tiny pieces of sand at

the bottom of the ocean.

• Over millions of years, the pieces of rock get pressed and cemented together. This turns the particles into sedimentary rock.

Answers should include two of the following tests or
