Weathering & Erosion
when rocks rub against each other becoming less jagged and more rounded
What is Abrasion?
movement of weathered rock, sediment , or particles from one place to another.
What is erosion?
Faster water can move this, and slower cannot.
What is large pieces of sediment?
True or False: Wind can carry smaller particles and sediment longer distances than larger, heavier particles.
True
This is the slow downhill movement of a large amount of rock and sediment due to gravity.
What is creep?
breaking down of rock and other material on the Earth's surface
What is Weathering
The Process of Oxygen combining with a chemical to form a new substance
What is oxidation?
This part of a river has been cut-off from the main channel and remains as its own source of water.
What is an oxbow lake?
True or False: Wind can also cause weathering through abrasion.
What is true?
This event occurs when a large amount of rock and sediment slide down a mountain or volcano.
What is a landslide?
Precipitation that often causes chemical weathering
What is Acid Rain?
The Process that results from oxidation and produces an orange color seen on iron rocks and objects.
What is rust?
What are meanders?
These are created at the edge of beaches by wind and help prevent further erosion.
What are sand dunes?
This event typically occurs after a long period of heavy rainfall so that soil particles are surrounded by water so the ground slides or does this.
What is slumping?
Large moving sheets of ice and snow that erode rock
What is a glacier
The Process of rocks breaking down not physically, but chemically.
What is Mechanical Weathering?
These are the three factors that impact water's ability to erode and deposit sediment.
What is volume, slope, and rocky or smooth surface?
This term describes the motion of soil particles by wind.
What is Deflation?
This event occurs when a large amount of rock, sediment, plant material and water flow down a mountain.
What is a mudflow?
The most common and powerful force for weathering & erosion.
What is running or moving water?
A type of weathering where a rock is changes into a different substance.
What is Chemical weathering?
What is a graded bedding?
An area of fertile soil created by wind erosion and deposition of minerals and nutrients for soil.
What is a loess?
This event occurs when a large rock breaks away from a landform.
What is rockfall?
