• sedimentary
• metamorphic
• volcanic

You observe slate is a metamorphic rock that splits into flat pieces. How is slate formed?

• Molten magma deep inside Earth.
• Lava erupts and runs down the side of a volcano.
• A large amount of of heat and pressure.
• Sediments are deposited over time and become cemented.

What rock is smooth, glassy, and formed from quickly cooled lava after a volcanic eruption?

• concrete
• metamorphic
• sedimentary
• igneous

What terms can be used to describe the luster of a rock?

• hard and coarse
• glassy and metallic
• metallic and soft
• grainy and rough

Which rock was most likely formed deep within the Earth?

• shale, metamorphic   
• pumice, igneous
• basalt, igneous
• sandstone, sedimentary

You observe that granite is made up of very large crystals. What are these crystals made up of?

• minerals
• shells
• fossils
• soils

You look at a poster describing different rocks. Which is mostly likely a sedimentary rock?

• obsidian- glassy and dark
• limestone- made up of many layers
• pumice- full of air pockets
• granite-speckled many colors

What property is being tested: scraping a mineral on a special plate to observe the color left?

• cleavage
• hardness
• luster
• streak

What property is being tested: you use a small hammer to break the mineral?

• cleavage
• luster
• texture
• streak

Mineral A: red, grainy, shiny, 8, brown streak.
Mineral B: red, grainy, shiny, 3, yellow streak

• Mineral A appears very different than Mineral B.
• Mineral A and B are not the same mineral.
• Mineral B can scratch Mineral A.
• Mineral A and B have the same properties.
