Physical Oceanography Prep for Sedimentation Quiz

Select 3 of the 4 Answer Options. The three types of rocks, also featured in the music video we watched in class, are:

• Igneous

• Metamorphic

• Sedimentary

• Lava

Particles of organic or inorganic matter that accumulate loose, unconsolidated form are called:

• Hydrologic Cycle

• Metamorphic Rocks

• Sediments

• Igneous Rocks

One of the following is NOT one of the ways sediments originate or are created.

• From the weathering and erosion of rocks

• From the inactivity of living organisms

• From volcanic eruptions

• From the behavior and movements of organisms while they were living

• From chemical processes within H₂O itself
