there was a good visual but I wish that he would be just a little more descriptive in how the layers formed other than that the pictures were great it was blurry on the Ipad but when I watched on the computer it was great. CML
very descriptive. I liked how it was telling the names of the layers and how its set up and the order very nice. One thing I liked more was how clearly it was to understand what's going on it. ASG
He did a very good description of how a soil horizon happens. I also liked the diagram when he dug in the ground next to the tree, very cool. He made the video very understandable.
1. A soil profile is a section dug out to view the different layers. (This is what I complimented about.) Layers are called horizons. 2. Roots from simple plants break down the rock beneath it, this is a very slow process though, not hyper speed. As this happens, the land becomes more fertile, allowing for more life. 3. Leaching is when rain comes and makes it's way through the soil, carrying minerals down with it into the lower layers. Most plant roots occur in the A, E, and B Horizons because of leaching. Q: Where can you most commonly find fossils in these layers. ADC Part 2
it was extremely helpful for information for being 4:34 seconds long. I liked how he showed the name of each lair wile he talked about it. what I think that he cold have dun bettor is using different pictures each time he change to a knew lair. what lair does petrol form.
It was well explained throughout the video on how each and every horizon had a different color because of the lack of nutrients, minerals, quantity of leaching, etc. What I thought was interesting was that a lot of soils don't have an E horizon, and the soils that do have one, occur mostly under forests with high rainfalls. Though I have a question about this...How is this supposed to help us in everyday life? Why is it important that people learn about this? I enjoyed learning about the different layers in a soil profile. I hope to learn more and better my understanding of it. MJS
1. its interesting to me that dirt layers out. why can't dirt stay mixed together throughout everywhere? it just stays in its own section. 2. its cool that plants roots can make it all the way down to the bed rock. 3. leaching is when water comes through the soil and caries some stuff down. most plant roots stay in the A, E, and B horizons probably because thats where the most water is.

1) He talked about soil profiles, which is a view of the layers of dirt. They are called horizons. There is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. 2) Some places don't have an E horizon. You mostly find that layer in places where it rains. 3) The deeper the soil is, the less nutrients there are. The soil on the top is more moist therefore more fertile, and also has the roots of plants breaking down rocks for better. Loam is found more at the top of the soil profile. My question would be, how long would it take for topsoil to become bedrock?? JJP
1.humus is made of decomposed organic matter. 2.soils change over time due to leaching, loss, addition, and altering. 3.everything is accumulated in the B horizon due to accumulation. Q: what is underneath bedrock? CJB
1. Soil layers have become more distinct over time. 2. Bedrock is the deepest layer on the soil horizon chart. 3. The topsoil is the most fertile. Q. How far away is the core of the Earth from bedrock? JMJ
Very descriptive. I liked the way it showed the broken away rock and the layers and roots were showing, very great visual!

I agree that it was a very clear visual too! The diagrams and pictures made it much easier to understand what he was talking about!

ooh.. that's a good question. :)
