I agree with Elijah that clay would absorb the most of the water because clay is very thick, which doesn’t allow any oil to reach to the ground water.

1. I think sand can go through oil pollution because sand has spaces, which can easily go through. 2. I think clay can absorb tons of amount of water because in my experiments, the clay drops tiny amount of water in the cylinder. 3. Looking through in my soil samples observation table, I see that clay holds tons of amount of water because clay is thick, and clay is as well clumpy.

I’m very impressed with your responses, Najee!

Hi Justin — you have a very good understanding about water movement through various soils.

Good thinking Elijah. But what happened to numbers 1 & 3?

I agree with najee on #2 becauseit is certain that the clay is most absorbent.

I agree with Justin.E completly but also clay can not let any liquids pass through.So it is a very thick material that when wet stays completly together not leting anything seak through. So its not so easy its not at all.

1. Pollution moves through sand, clay, and top soil not too quickly. Liquids go through top soil easily. Liquids go through clay not to easily because clay is very absorbant.
2. Clay holds the most liquids because in my experiment out of all the soils, clay allwoed the least amount of water to go through. If ground water were to be underneathe clay it would eventually be absorbed.
3. I think soil factors that determine how much water it canabsorb depends on what it is used for. Clay is meant to be wet so it absorbs a lot of water. Sand and top soil aren’t made to absorb water so they don’t absorb so much. Sand is to grainy and doesn’t absorb much and top soil has sticks and pebbles mixed in and doesn’t absorb a lot of liquids.
