Exploring Rocks and the Rock Cycle

Which type of rock is formed when molten magma cools and solidifies?

• Sedimentary rock

• Igneous rock

• Metamorphic rock

• Limestone

What is the main process that forms sedimentary rocks?

• Melting

• Cooling

• Compaction and cementation

• Evaporation

Which of the following is an example of a metamorphic rock?

• Granite

• Sandstone

• Marble

• Basalt

What is the correct order of the stages in the rock cycle, starting with magma?

• Magma → Sedimentary rock → Metamorphic rock → Igneous rock

• Magma → Igneous rock → Sedimentary rock → Metamorphic rock

• Magma → Metamorphic rock → Sedimentary rock → Igneous rock

• Magma → Sedimentary rock → Igneous rock → Metamorphic rock

Which process changes sedimentary rock into metamorphic rock?

• Melting

• Weathering

• Heat and pressure

• Erosion

Which of the following rocks is most likely to contain fossils?

• Granite

• Marble

• Sandstone

• Basalt

What is the main difference between intrusive and extrusive igneous rocks?
