• Identify various processes and activities that promote soil formation

Examples: weathering, decomposition, depostion

How Fast Do Sediment Grains of Different Sizes Settle?
Students will define rate, turbidity, and settling rate and explain the relation between settling rate and turbidity.
Students will interpret change in turbidity with time as a function of settling rates of sediment of different grain sizes.
Students will predict how the clarity of water in a stream or in the ocean will differ during periods of flood vs. low water, or during a storm vs. between storms, and explain the basis for this prediction
