Explanation:

These are 5 inverted cut bottles with different soils:

(Gravel, Sand, Loam, Clay, and Peat)

- The piece of cloth is tied at the mouth of the bottle to let out water at the same rate as the piece of cotton wool in the previous diagram.

- Soil that is very porous holds very little water and therefore allows too much water to pass through it.

- From the above, gravel has very large particles,it allows too much water to pass through it meaning it holds little water.

- Peat has more fine particles than Clay Soil, hence holds more water than Clay. It therefore allows very little water to pass through it.
