Data Analysis: Rock Cycle

Which sample likely formed from cooling lava at the ocean floor?

• Sample A

• Sample B

• Sample C

• Sample D

Which sample formed under intense heat and pressure in a convergent boundary?

• Sample A

• Sample B

• Sample C

• Sample D

What does the presence of fossils in Sample B suggest about its origin?

• It formed deep underground

• It was formed from magma

• It was once part of a living environment

• It came from a volcanic eruption

If a rock is weathered and the sediments are later compacted, what type of rock is formed?

• Igneous

• Sedimentary

• Metamorphic

• Lava

What process must happen to turn any rock into magma?

• Compaction

• Erosion

• Melting

• Cooling

Once magma cools, what type of rock forms?

• Metamorphic

• Sedimentary

• Igneous

• Fossil

How can a sedimentary rock become metamorphic?

• Melting and cooling

• Heat and pressure

• Weathering

• Compacting and cementing

What processes are necessary to turn metamorphic rock into sedimentary rock?

• Melting then cooling

• Weathering and compaction

• Heat and pressure

• Rapid cooling

New igneous rock forms at divergent boundaries like ___________.

• mountain range

• continental basin

• mid-ocean ridges

• continental crust edge

• river delta

Sedimentary rock typically forms in low-energy environments like ___________.

• continental basin

• mountain range

• mid-ocean ridges

• continental crust edger

• river delta
