Rocks, Weathering and Erosion Quiz Review

1. Draw and label the rock cycle below. Include the following:

a. The three major rock types

b. Sediment and magma

c. Arrows labeled with the processes of melting; cooling and crystallizing; weathering and erosion; deposition and cementation; intense heat and pressure.

2. Using complete sentences, explain the difference between intrusive and extrusive igneous rocks. Discuss where each is formed, how it cools, and what types of grains are associated with each. Finally, GIVE AN EXAMPLE OF EACH.

3. Classify each of the following as either a mineral, a rock or an ore.

a. Calaverite is composed of tellurium and gold. It is mined for to produce valuable jewelry.

b. Albite is a type of feldspar that crystallizes in nearly right angle prisms. Commonly found in many types of rocks, it is the most common type of feldspar.

c. Basalt is often found in flows near volcanoes. It is dark and contains small air bubbles in places where gas was trapped in the cooling magma.

4. Explain which resource is more economically viable for extracting aluminum (Al), the ore bauxite Al(OH)₃ or the recycled aluminum alloy Al₃SC. (HINT: Use the atomic weights like we did with the Cookie Mining Lab).
