1. A scientist observes that a rck sample has grains that are flat and form long bands. What inference can the scientist make about what type of rock the sample is?
2. Cools and hardens
3. Gneiss and Marble
4. In the rock cycle, what mst occur for igneous rock to become sedimentary rock?
5. Pressed together and hardens
6. The continuous series of changes that rocks undergo ?
7. There are minerals with metallic luster and minerals that are glassy or dull. What other properties can help you identify minerals?

6 Multiple Choice Questions

1. The color of a mineral when it is ground to a powder is its ?
   1. Streak
   2. Sedimentary
   3. Sediment
   4. Talc
2. You have two igneous rock samples. Sample A has large crystals and Sample B has very small crystals. What could you conclude about how quickly each sample cooled as it formed?
   1. The continuous series of changes that rocks undergo is called the rock cycle. Igneous rocks must be weathered into sediment to become sedimentary rocks
   2. Rocks with flat grains that form long bands have been subjected to heat and pressure, so they would be metamorphic rocks
   3. Luster, hardness, cleavage, color, and streak
   4. Igneous rock is formed when molten rock from a volcano cools and hardens. Large crystals cooled more slowly than Sample B
3. Made up of igneous, sedimentary, and metamorphic rocks
   1. Rock cycle
   2. Igneous rock
   3. Metamorphic rock
   4. Earth's crust
4. A friend has a set of mineral samples and wants to identify them. What would you suggest he or she do?
   1. Rocks with flat grains that form long bands have been subjected to heat and pressure, so they would be metamorphic rocks
   2. The continuous series of changes that rocks undergo is called the rock cycle. Igneous rocks must be weathered into sediment to become sedimentary rocks
   3. The properties of a mineral can be determined by 1- observing the mineral properties, 2- carrying out a series of tests, 3- comparing with properties listed in a table of minerals
   4. Luster, hardness, cleavage, color, and streak
5. Sand, bits of rock, and the remains of once-living things are?
   1. Sediment
   2. Sedimentary rock
   3. Streak
   4. Sedimentary
6. Granite, basalt, and obsidian
   1. Inner core
   2. Igneous rocks
   3. Igneous rock
   4. Streak
