2: Sediment Creation and Transport
Sediment is formed by the weathering of existing rocks and minerals. This sediment can be eroded (transported from one location to another) in a variety of ways by moving fluids or under the direct influence of gravity. Sediment will eventually be deposited and might eventually be transformed into sedimentary rock.
- Explain the difference between physical and chemical weathering and provide examples of each.
- Define the most important properties of fluids and sedimentary particles and use this knowledge to make predictions about how these properties will influence fluid motion and sediment transport.
- Describe, identify, and explain the differences between the three types of fluid flow transport
- Describe, identify, and explain the differences between the four types of sediment gravity flows

- 2.3: Fluid-Flow Transport
- There are three different ways that moving fluid can carry sediment. Dissolved load is the movement of dissolved ions, suspended load is when particles are held aloft by turbulence, and bedload transport happens when the fluid causes particles to move through rolling, tumbling, saltation, etc.
