Earth's Materials / The Rock Cycle Multiple Choice Assessment

1. Based on this rock's properties of a shiny, glass-like appearance, which rock classification would it most likely fit into?

• Sedimentary
• Metamorphic
• Igneous

2. Based on this rock's properties, which classification would it most likely belong to? Observable properties include: Ribbon-like layers, very dense, crystal content (hint: ribbon-like layers ONLY form under intense heat and pressure)

• Sedimentary
• Metamorphic
• Igneous

3. Based on this rock's properties, which classification would it most likely fit into? (Hint: looks like it may have been made using compaction and cementation.)

• Sedimentary
• Metamorphic
• Igneous

NGSS.MS-ESS2-1

4. Based on this rock's properties, which classification would it most likely belong to? Observable properties include: Gas bubbles, low-density, smooth (Hint: bubbles usually form from liquids-think what rock may involve a liquid forming it.)

• Sedimentary
• Metamorphic
• Igneous

5. Based on this rock's properties, which classification would it most likely belong to? Observable properties include: very grainy, rough texture, not very dense (Hint: looks like sand, maybe it has some sediment in it)

• Sedimentary
• Metamorphic
• Igneous

6. Which classification of rock is formed by the geoscience processes of HEAT and PRESSURE?

• Sedimentary
• Metamophic
• Igneous

7. Which classification of rock is associated with the MELTING and COOLING/CRYSTALLIZATION of magma/lava?

• Sedimentary
• Metamorphic
• Igneous

8. The geosciences processes of COMPACTION & CEMENTATION form which classification of rock?

• Sedimentary
• Metamorphic
• Igneous

9. Ribbon-like layers of a metamorphic rock will appear within the rock if it formed due to/under.......

• Deposition
• Erosion
• Pressure

10. Which classification of rock consists of two types - INTRUSIVE and EXTRUSIVE?

• Sedimentary
• Metamorphic
• Igneous
