Definition of Erosion
Process in which weathered pieces of the lithosphere are moved from on place to another
Occurs because of Weathering
![Page 4: Aim: What is Erosion? Objective: Ability to differentiate the different type of weathering Vocabulary: mechanical weathering, chemical weathering, carbonation,](https://reader035.vdocuments.site/reader035/viewer/2022062801/56649e3f5503460f94b30032/html5/thumbnails/4.jpg)
Weathering
Is the decay of rocks, minerals, mountains, and other hard surfaces of the earth
The decay breaks larger particles into smaller ones
The decay can either be mechanical or chemical or both

What happens when two rocks bang into each other?
Little chips of the rocks break off Sometimes large chips, sometimes small
ones. Multiply that by 1,000,000 years Will the original rocks be larger or smaller Mechanical Weathering

Freeze-Thaw Cycle
If you put a can of soda in the freezer what happens?
The same things happens in nature when water freezes
Over millions of years – changes the lithosphere breaking parts of it into millions of pieces

the larger the particles (sediment)
the water is able to move !

Chemical Weathering
Chemical weathering is where the rock material is changed into another substance by reacting with a chemical.
1. Oxidation:
2. Hydrolysis:
![Page 32: Aim: What is Erosion? Objective: Ability to differentiate the different type of weathering Vocabulary: mechanical weathering, chemical weathering, carbonation,](https://reader035.vdocuments.site/reader035/viewer/2022062801/56649e3f5503460f94b30032/html5/thumbnails/32.jpg)
Oxidation is another form of chemical weathering
Your bicycle if made of iron What happens to it in the rain Turns to rust Oxygen + Iron = Iron Oxide (rust) Water is a catalyst = speeds up the process
![Page 33: Aim: What is Erosion? Objective: Ability to differentiate the different type of weathering Vocabulary: mechanical weathering, chemical weathering, carbonation,](https://reader035.vdocuments.site/reader035/viewer/2022062801/56649e3f5503460f94b30032/html5/thumbnails/33.jpg)
Weathering can also be chemical
Carbon dioxide (air) mixes with water (rain) to form carbonic acid
Carbonic acid can dissolve some sedimentary rocks – particularly limestone
Over millions of years this forms large caves and caverns. (Howe Caverns)
Often when water combines with limestone or marble an acid is formed
![Page 34: Aim: What is Erosion? Objective: Ability to differentiate the different type of weathering Vocabulary: mechanical weathering, chemical weathering, carbonation,](https://reader035.vdocuments.site/reader035/viewer/2022062801/56649e3f5503460f94b30032/html5/thumbnails/34.jpg)

Hydrolysis is another form of chemical weathering
Water has a tendency to dissolve other substances
Water is called the universal solvent When water combines with another
substance is called hydrolysis
![Page 37: Aim: What is Erosion? Objective: Ability to differentiate the different type of weathering Vocabulary: mechanical weathering, chemical weathering, carbonation,](https://reader035.vdocuments.site/reader035/viewer/2022062801/56649e3f5503460f94b30032/html5/thumbnails/37.jpg)
Rates of weathering will be influenced by surface area: More surface exposed, the faster the weathering will occur.
