- Introduction:
Is soil erosion a problem in NZ?:
Ans: yes
- Experiment 1: Soil erosion
- We put a soil and water in the container because
We´re trying to investigate how soil wash away from
The water.
- Experiment 2: Effect of vegetation (plant)
- There´s a grass, soil and soil with leaves so we do the grass one first
And we put some water on the top on it and there´s measuring cup
Under the grass and when we put the water in the grass the water turns
to a blurry water. Our second experiment was the soil and we do the
Same thing that we did in first experiment, and the result was really
Dirt water. And the last one was soil with leaves and the result was
A little bit clear water.
