  1. Define:MineralRocksCrystal 130 120 60 70 40 50 30 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  2. Mineral - inorganic, solid materials found in nature • Rocks - are made of two or more minerals • Crystal - solid material with atoms arranged in a repeating pattern

  3. Describe how are minerals formed from magma? 130 120 60 70 40 50 30 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  4. As magma cools, atoms combine in orderly patterns to form minerals. Minerals also form from melted rock that reaches Earth's surface or lava.

  5. Explain cleavage and fracture 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 20 90 160 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  6. Minerals that split into pieces with smooth, regular planes that reflect light are said to have cleavage. • Minerals that break into pieces with jagged or rough edges have fracture.

  7. Make a table showing Moh’s Scale of Harness 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 20 90 160 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  8. List some properties that are used most commonly to identify minerals. 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 20 90 160 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  9. Color • Harness • Luster • Streak • Fracture • Cleavage

  10. Describe the three types of rocks 130 120 60 70 40 50 30 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  11. Igneous - Rock formed when molten (melted) materials harden. • Sedimentary - Rock formed from sediment (sand, mud, animal remains, etc) on the surface of the earth • Metamorphic - Rock that has been physically altered by heat and/or pressure.

  12. Describe how a metamorphic rock might change into an igneous rock. 130 120 60 70 40 50 30 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  13. If metamorphic rock is heated enough to melt, magma forms. Once magma cools and crystallizes igneous rock forms.

  14. Draw a diagram illustrating the rock cycle 130 120 60 70 40 50 30 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.
