Chemical Weathering Types
Chemical Weathering
100
What is the definition of weathering?
Breaking rocks down into smaller pieces.
100
This type of mechanical weathering happens as a result of water freezing in a crack of a rock repeatedly.
What is Frost Wedging.
100
Carbon Dioxide in the air mixes with water to produce what?
Carbonic Acid
100
Explain what caused this?
Weak acid rain over long periods of time
200
This is a type of weathering that only affects the surface of a rock and involves a chemical change, such as color change or dissolving.
What is Chemical Weathering
200
Frost wedging is most effective in this climate.
What is Cold and Wet.
200
What is oxidation?
Chemical reaction with iron rich minerals to produce rust or iron oxide.
200
What chemical weathering type caused this?
Hydration
300
This process breaks down rocks into smaller pieces that are the same as the original rock.
What is Mechanical Weathering
300
How do tree roots weather rocks mechanically?
By growing and slowly prying into rocks.
300
Explain how caves form using the process of hydration to help you.
Water dissolves minerals in rocks leaving an empty space.
300
What is hydration?
Water dissolves minerals in rocks, leaving empty spaces.
400
Weathering processes are slower in this kind of climate.
What is dry
400
What type of climate does Mechanical weathering occur in most (Hot, Cold, Wet, and Dry)
Cold and Wet
400
Explain how the surface process of chemical weathering speeds up or makes it easier for mechanical weathering to occur.
Chemical weathering weakens the surface which makes it easier for ice wedging to occur.
400
Explain how lichens chemically weather rocks.
They are a fungi and a plant that produces an acid in its roots which chemically weathers rocks.
500
Chemical weathering occurs fastest in what type of climate? (Hot, Cold, Wet, and Dry)
Hot and Wet Climates due to the amount of rainfall
500
What type of climate experiences the most mechanical weathering?
What is the North Eastern United States (Cold and wet which means large amounts of rain occurs and freezing as well)
500
Which location will chemical weathering occur the most in?
South Eastern United States (Florida is hot and wet which produces large amounts of rain)
500
What is this type of chemical weathering called?
What is oxidation
