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
The oxidation of minerals that contain iron.
Chemical Weathering
Rusting in science is know by this term.
oxidation
The name for fragments of broken rock.
Sediments.
How do glaciers contribute to erosion?
They scrape sediments and deposit them and water in other areas.
Mountain.
Lifted sections of sidewalk along tree lined streets.
Mechanical Weathering
This is the large triangle shaped formation at the end of a river.
A delta
Most caves in Minnesota are made from this weathering process.
Dissolving of Limestone
Which agent of erosion can form sand dunes?
Wind
A wetland area that forms as river waters empty sediments into a larger body of water.
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 whereby particles of rock are eroded away by friction.
Abrasion.
What variable impacted the sediment's deposition in our Deposition and Slope Lab the most
The slope.
Acids form plant roots which break up 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 erosion force acts the most to produce avalanches and landslides?
Gravity
Most weathering on a beach is caused by this agent.
waves
Animal burrows dig in the ground that allows water and air to enter in.
Mechanical Weathering.
Glaciers make this shape valley.
