Reflection: This week I learned a lot of new things I never new about soil and soil erosion.We learned the 3 different types of soil along with their profiles, structures, and textures. We also learned about the different types of erosion and how we can prevent it. Going around the campus taking pictures helped me realize the many different types of erosion and where they take place. The rain box activity really helped me realize the effectiveness of the different types of products and methods that can stop or slow down erosion. These things are important because they will help us with our experiences later in life, such as if we plan on building a house, planting a garden, or building a tool shed. We would need knowledge of soil erosion for these tasks because we wouldn't want our house or shed moving when it rains, or planting a garden that wont grow because the soil got washed away and now the plants wont have the necessities they need.
Vocabulary:
1.
Transport- When water carries soil to a different location.
2.
Rill- A small rivulet or brook.
3.
Gully- A small valley or ravine originally eroded away by running water.
4.
Detachment- Separation of soil from other soil particles.
5
.Soil Erosion- the movement of soil from one location to another.
Questions:
1. Instead of having a legal limit for the amount of sediment in the water runoff to protect the fish and the quality of the water, why not just prohibit runoff in general and have it go to another place?
2. Since there are laws about how much soil erosion a construction site can have, why doesn't tax money go to erosion prevention instead of the construction companies paying for it?
3. Would it be safe to have wire filters in a yard to prevent soil erosion since the metals can get into the
water and contaminate it?
Our groups rain box experiment, we used hay, mulch, coconut strands, rocks, and had a wire filter at the end of our tube.

Here is a good example of
transportation in a
gully. Notice the color of the water, because of all the sediment it is carrying .
I think that if the runoff were prohibited construction sites would have a harder time building and moving things. They would have to move everything they pushed aside and it'll cost more money to do so. Plus, they can't really stop the sediment all from running if it starts to rain.
