The Grand Canyon demonstrates cross-cutting by the layers of rock it has. Cross-cutting is the geology of rock formation and the Grand Canyon has rock all over to observe. Also the Grand Canyon demonstrates cross-cutting because geologists can observe the types of rock the Grand Canyon has and how the rock forms and when it can't form at all. The Grand Canyon can also demonstrate cross-cutting because the Grand Canyon has many cracks and can be observed of how they formed. Also the Grand Canyon demonstrates cross-cutting by the type of rock it has and can be observed by people who are studying the formation of rock.
The Grand Canyon demonstrates superposition by its size. Superposition is the deposition of one geological stratum on another. Also the Grand Canyon demonstrates superposition because the Grand Canyon can get bigger by the formation of the rock it has. The Grand Canyon moves by the earth plates that move and that is how superposition comes in. When the earth's plates move, the Grand Canyon splits up and superposition comes in. These were examples about how the grand Canyon demonstrates superposition and crosscutting.
First of all, peppered moths changed color in England because of the factories people built. Because of the factories smoke came out and the peppered moths changed color. Also the factories made the peppered moths to change color because of the pollution the factories made and got out. Since the peppered moths got used to the pollution in the dark forests, the dark moths couldn't be in a forest that was not polluted. The peppered moths also changed color because of the DNA the parents passed to offspring. Since all of the moths can't be the same color then the parents passed on traits.
The peppered moths also changed color because of the evolution. At first the moths were this color, then when they were growing, the moths began to change color. Also the peppered moths in the light forests did not change color because they didn't live ina place where there were factories or the pollution. So the light colored moths did'nt change color because they lived in light forests. If you put a dark moth in a light forest, it would not adapt to the clean forest. If you put a light moth in a dark forests then the moth would not survive because it is not used to the environment in the dark forests, That is why peppered moths changed color.
Evolution is when an animal changes over time and changes its instincts. I think that over population leads to evolution because for example peppered moths are light and dark. The light moths live in light forests and dark moths live in dark forests. Why do you think they call the forest dark? Well first of peppered moths are found in England and in England people built factories. The factories had to be run by coal. So when the smoke gets out, the trees from the forest get dark too. The trees get dark too because the factories are polluting the air. So when the peppered moths go and fly out the pollution of the smoke got on the moth and the moth turned black. Also, the population leads to evolution because the factories that were built in England were polluting the forests, the forests got dark and barren, and the moths got polluted too. The dark moths got used to the pollution that the dark moths can't live in light forests, and the light moths got used to the clean air that they can't live in dark forests.
I learned all of this in science. We were doing a project and you had to go to a website where it gave facts about the peppered moths. It had sections and it was in order. it gave facts about peppered moths, where they lived, how they looked like, and how they lived. This was a bit of information and what I learned about evolution.
In science we did a project of a paper pet family. The first thing we had to do was to do the Punnett Squares for the parents which was the person sitting next to you. After we have found the genotypes we had to flip a penny to find out how our children will look like. The curve sign was a girl and the straight line was a boy. When we flipped the coin, if it landed on heads the genotype for one of the phenotypes would be a uppercase letter. If the coin landed on tails the genotype would be a lowercase letter. When you have all of your phenotypes for the children, you had to name your children. If it had the curve it was a girl and if it was a straight line it would be a boy. The uppercase letter is the dominant allele and the small letter is the recessive allele. After you have named all of your children then you would get a white piece of paper and put the parents and the children on the paper. By the way, we had to draw the face of the parents and the children.
The project didn't relate much to my family because the phenotypes of the children and the parents were round eyes vs square eyes, pointed teeth vs square teeth, and other phenotypes. I learned how to find the genotypes of the children to compare the genotypes of the parents. I also learned how to use the Punnett Squares and how to fill them out and how to get all of the phenotypes. I also learned how to do the heads/tails to get the genotype of the kids. That is what I did and learned about the paper pet family.
