See explanation below
Explanation:
-
Independent variable is what you are changing constantly. It is not dependent on any thing and nothing affects it.
-
Dependent variable is what you are measuring. It is dependent on the independent variable and it changes every time you change the independent variable.
-
Control variable is what you keep the same throughout the experiment. It can be amount of something or type of something. If these factors are not controlled, they may affect your final result.
For your experiment,
-Independent variable: speed of water
- Dependent variable: amount of soil/particles it carries
- Control variable: velocity of the water, surface of the land which water flows over and amount of water in the river.
Also may be how often you record your data must be the same.
