Rock Cycle Concepts and Processes

Mrs. Furlough introduces the rock cycle, discussing igneous, sedimentary, and metamorphic rocks. She explains how each type forms and the processes involved, such as cooling, weathering, erosion, compaction, and cementation. The video concludes with a summary of the rock cycle and its variations.

What is the main topic introduced at the beginning of the video?

• The nitrogen cycle

• The carbon cycle

• The rock cycle

• The water cycle

What type of rock is formed when magma cools below the Earth's surface?

• Extrusive igneous rock

• Sedimentary rock

• Intrusive igneous rock

• Metamorphic rock

Which process involves the breaking down of rocks into smaller pieces?

• Weathering

• Cementation

• Melting

• Compaction

What happens during the cementation process in sedimentary rock formation?

• Rocks are eroded

• Rocks are melted

• Rocks are compacted

• Rocks are glued together

What causes metamorphic rocks to form?

• Compaction and cementation

• Erosion and weathering

• Extreme heat and pressure

• Cooling of lava

Which type of rock is formed from existing rocks that are buried and subjected to heat and pressure?

• Volcanic rock

• Igneous rock

• Sedimentary rock

• Metamorphic rock

What is the primary factor that determines the type of rock formed in the rock cycle?

• The size of the rock

• The location of the rock

• The process by which it forms

• The color of the rock

Which type of rock can contain fossils?

• Metamorphic rock

• Volcanic rock

• Sedimentary rock

• Igneous rock

What can happen to metamorphic rock if it is exposed to the Earth's surface?

• It becomes igneous rock

• It becomes sedimentary rock

• It melts completely

• It remains unchanged

Which of the following is NOT a type of rock in the rock cycle?

• Volcanic rock

• Igneous rock

• Metamorphic rock

• Sedimentary rock
