Question | Answer |
---|---|
erosion - | the process of moving sediment by wind, water, ice, or gravity |
river - | a large body of water that flows into an ocean or lake. |
stream - | a small river |
channel - | the path that a river or stream follows |
deposition - | the process of depositing sediment after it has been moved by water, wind, ice, or gravity. |
graded bedding - | a layer of sediment with the largest particles at the bottom and smallest particles on top; the particles are deposited as flowing water slows down. |
direction of younging - | the order in which sedimentary rock layers are formed—from larger to finer particles. |
cross bedding - | a pattern of alternating beds of sediment that often form as wind and water deposit the sediments. |
mass wasting - | the downhill movement of large amounts of rock and sediment due to the force of gravity |
landslide - | a large mass of soil or rock that slides down a volcano or mountain. Landslides can be caused by volcanic events, earthquakes, or other factors |
rockfall - | an event that results in a large amount of rock splitting off of a landform |
mudflow - | an event that occurs when a large amount of rock, sediment, plant material, and water flows down a mountain. |
slumping - | an event that occurs when soil particles become surrounded by water so that the ground slides or “slumps". |
