Weathering
Weathering
The process of moving rocks, soil, and sand by means of water and wind.
Erosion
A mass of ice that covers a large area and moves slowly.
Glacier
Oxidation is this kind of weathering.....
Chemical Weathering
Rusting in science is know by this term.
oxidation
Fragments of broken rock.
Sediments.
How do glaciers contribute to erosion?
The scrape rocks with ice and deposit boulders and water
Convergent plate movement can cause this type of landform.
Mountain.
Lifted sections of sidewalk along tree lined streets are this kind of weathering......
Mechanical Weathering
This is the large triangle shaped formation at the end of a river.
What is a delta?
Most caves in Minnesota are made from this weathering process.
Dissolving of Limestone
Which agent of erosion can form sand dunes?
Wind
An area that forms as river waters empty sediments into a larger body of water. It is shaped like a triangle.
Delta
Decaying plants dissolve some of the minerals in the rocks.......
Chemical Weathering
True or False: Landslides are small scale and fast GeoScience processes.
True.
Where would you most likely find rocks that are smooth or rounded?
In a fast moving river or stream.
The physical process of rubbing, scouring, or scraping where particles of rock are eroded away by friction.
Abrasion.
Increasing this variable changed the amount of sediment deposition in our Deposition and Slope Lab the most
The slope.
Acids from plant roots like lichen break up minerals in rocks.......
Chemical Weathering.
When the act of freezing water breaks rocks, it is called this process.
ice/frost wedging
What are the main 3 agents that break down rocks?
Water, Wind, and Ice.
Which erosional force acts alone to produce avalanches and landslides?
Gravity
Most weathering on a beach is caused by this agent.
waves
Animals burrow in the ground that allows water and air to enter in.
Mechanical Weathering.
Glaciers make this shape valley.
U-Shaped
