Study Notes
Weathering
- Weathering is the breakdown of rocks into smaller sediments.
- Two primary types of weathering:
- Physical weathering, which involves mechanical forces.
- Chemical weathering, which involves chemical reactions altering the rock's composition.
Erosion
- Erosion is the transportation of sediments by natural forces such as water, glaciers, and wind.
- Weathering is the process that generates the particles involved in erosion.
Deposition
- Deposition occurs when gravity causes sediments to settle at a new location after being transported.
Forces of Erosion and Deposition
- Gravity is the principal force driving both erosion and deposition processes.
Agents of Erosion
- The three main agents responsible for erosion are:
- Moving water
- Wind
- Ice
Deltas
- A delta is a fan-shaped deposit of sediment found at the base of a mountain where a stream flows into a flatter plain.
- Weathering, erosion, and deposition collaborate to create a delta:
- Weathering breaks rocks into sediments.
- Erosion transports these sediments to a new location.
- Deposition settles the sediments at the delta's base.
Oxbow Lakes and Meanders
- A meander is a bend or curve in a stream.
- An oxbow lake forms when a meander is cut off from the main stream during flooding, creating a separate lake.
- Flooding can cause a stream to reroute, bypassing a meander and forming an oxbow lake.
Physical vs. Chemical Weathering
- Physical weathering involves breaking down rocks without changing their composition.
- Chemical weathering involves alterations in rock composition due to chemical reactions.
- Both types of weathering aim to reduce rocks to sediments, allowing for erosion and deposition processes.
