Weathering & Erosion
The wearing away of Earth’s surface by wind, water, or glacial action. It moves materials from one place to another.
What is Erosion?
When glaciers melt or recede, the rocks get ____________ at the front edge
What is deposited?
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?
A natural force that breaks down rock into small particles
What is Weathering
Glaciers will move smaller particles which will scrape against rocks. This is also as known as this process.
What is abrasion?
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?
An example of this is when acid in water dissolves rock like limestone.
What is Chemical Weathering?
The rocks and sediment deposited by glaciers.
What is glacial till?
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?
When wind and water break down and disintegrate rocks
What is Mechanical Weathering?
Glacial erosion is so powerful that it can carve out deep landforms called this.
What are u-shaped valleys?
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?
Glaciers can be found on all continents except this one.
What is Australia?
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?
