The Grand Canyon is made of many layers of sediments. If you look at a photo of the Grand Canyon, there are many thin layers of sediments that make up the Grand Canyon. Also, according to Superposition, the older layers are on the bottom, and the newer layers are on top. Also, In the Grand Canyon there are also places which demonstrate cross-cutting. There are also intrusions in the Grand Canyon which interfere with the building of layers. According to the pictures of the Grand Canyon I have seen, all the sediment layers are flat and straight, but I assure you there are also areas which have intruded by molten lava. Cross-cutting can cause certain areas of the Grand Canyon to be higher than the next like stair steps.
In England, 99% of the moths were white before the start of the industrial age. After the Industrial Age began, there was a high increase in pollution which lead to the trees of England. Along with this, there was a genetic variation among a peppered moth which caused it to be black. This peppered moth survived, while the other peppered moths were killed and eaten by birds. This black peppered moth survived and reproduce. Since the black peppered moths were fit to survive, when they reproduced, their larvae were also black which led to them surviving while the other white moths died out. Before the Industrial Age, 99% of the moths were white, and 1% of moths were black. Now 99% of the moths are black, and 1% of moths are white and this is due to the Industrial Age.
In Overpopulation, only the most successful survive and reproduce. Think of it this way. There are 100 people, and there are 60 pounds of salt, and each of those people need 1 pound of salt. Not everybody is going to get salt. 40 people are not going to get salt, and they will die. The other 60, will be able to survive and will reproduce. Note the fact that these people had something that the other 40 didn't. Maybe the 40 people were to short. That way, the short people died, and there are only the 60 tall people. The children of those 60 people may have another necessity that is needed to live such as a phone. Not all of the kids are going to have phones, so the ones that don't will die. This will leave us with kids who have cell phones.
This is what happens when Overpopulation. Theoretically speaking, if people are not able to survive on other planets anytime soon, the population will exceed the amount of resources we have, and humans will start to die out, and we will evolve. Our adaptation may be smaller stomach so we eat less. I have no idea what it will be. We may turn into dolphins if sea level continues to rise. | AuthorI like to play the chinese yo-yo which is also called a diabolo ArchivesJune 2013 Categories |
