Sedimentary Rock Cycle Concepts

The video tutorial explains the sedimentary rock cycle, starting with weathering, which breaks down rocks into small particles. These particles are transported and deposited in bodies of water, forming layers through sedimentation. Over time, compaction and cementation occur, solidifying these layers into sedimentary rocks. The cycle is continuous, as weathering affects these rocks, starting the process anew.

What are the three types of weathering discussed in the video?

• Biological, thermal, and physical

• Physical, thermal, and chemical

• Thermal, chemical, and biological

• Biological, chemical, and physical

What is the first stage of the sedimentary rock cycle?

• Cementation

• Compaction

• Sedimentation

• Deposition

During deposition, what happens to the sediments?

• They are weathered

• They are cemented together

• They are deposited in water bodies

• They are compacted

What is the second stage of the sedimentary rock cycle?

• Weathering

• Sedimentation

• Compaction

• Deposition

What forms during the sedimentation stage?

• Sediment layers

• Igneous rocks

• New minerals

• Metamorphic rocks

What is the third stage of the sedimentary rock cycle?

• Weathering

• Sedimentation

• Compaction and Cementation

• Deposition

What causes the sediments to compact and cement together?

• Heat

• Pressure

• Wind

• Water

What role do naturally occurring salts play in the sedimentary rock cycle?

• They prevent compaction

• They cause weathering

• They leach and fill gaps between sediments

• They dissolve the sediments

Why is the sedimentary rock cycle considered a cycle?

• Because it ends with weathering

• Because it starts with compaction

• Because weathering restarts the process

• Because it only happens once

What natural forces contribute to the weathering of sedimentary rocks?

• Sunlight and darkness

• Fire and ice

• Wind and water

• Earthquakes and volcanoes
