Summary: The week began with the presentations of our rivers. After hearing everyone's presentations My table group and I really started to put ideas together. We discussed what most of the rivers presented have in common. One main issue almost all the rivers was pollution. Most rivers were polluted by trash, gasses, and oils. Another thing the rivers have in common is they provided as natural resources for the ethnic groups that lived by the river. The river gave the people water, fertile land, fish and more depending on which river. The rivers were used to import and export goods which helped build trade. As well as that, most rivers had hydro electric stations and dams even though only some caused problems. Later on, we began to talk about the Gray Area and it's big problem. For the past five years, the Gray Area has lost about 1,000 fish per year. Almost everyone thinks the water slide is the culprit because it opened up the same year the fish started dying. We went throug...

Summary: We continued working on our project on the Ob River. I learned quite a lot on the Ob River this week and I think that information really helped our project. This week I learned about the environmental and cultural significance because we all shared the information we had on our research topics. After we shared that information, we worked on what will happen if people don't help and how people can help. I now know that the Ob River is home to about 50 different species of fish. The area around the Ob River has very rich soil, known as peat soil, which helps the crops grow. As well as that, I know that during winter the water freezes causing oxygen loss to the wildlife in the river. The middle and lower section of the Ob is very polluted due to people dropping of oils and gasses. I know that one main group of people, the Khanty people, live around and near to the foothills and mountainous areas of the Ob River.  The Khanty people were originally known by the Russians as the ...

Summary: This week we started our Rivers Project. My group and I chose the Ob River, a river that isn't that popular, but is still very important. I found many interesting facts on the economical significance of the Ob River, as well as the features of the Ob. I now know that the Ob River can produce up to 250 billion kilowatts, even though there are only three hydroelectric power stations built on the river. The importing and exporting of important goods occur along the Ob River. The supply of wheat for Russia is mainly produced in the area of the southern Ob basin. Wheat is not the only thing that blossoms by the Ob, about 2/3 of the country's oil and gas comes from the tiaga and tundra, near the Ob. As well as that, I know that the Ob empties into the Kara Sea of the Arctic ocean and the Ob-Irtysh is the main tributary coming from the Ob River and has a length of 3,362 miles. I also know that the mouth of the river is known as the Gulf of Ob and the Ob River is the fourth la...

       China should not build any more hydroelectric dams along the Jinsa or Yangtze River. Building the Three Gorges Dam disrupted the ecosystem and caused many environmental problems. It caused damage to the wildlife, surrounding people, and somewhat the river. Due to the dam, millions had to leave their homes and families with very little or no financial help. Mostly farmers were forced to leave the comfortable homes and farm where the land was not as good. Many historical treasures and archeological digging sites were ruined because of the dam. Treasures from original Chinese cultures can now never be found. The Three Gorges Dam disrupted the environment and people.       The wildlife in the Yangtze River and the surrounding people were greatly affected by the Three Gorges Dam, but not in a good way. Dangerous erosion was caused due to construction on the reservoir banks. After the reservoir was built risks of landslides increased around seventy ...

commons.wikimedia.org Summary: After finishing every one's erosion presentations we learned about the parts of a river and where they normally are on a river. We started off by labeling the main parts of a river together, the source, tributary, confluence, meanders, and the mouth. The source is where the river begins, there may be more than one. The tributary is a small portion of water that joins the main river. The confluence is the area where the tributary joins the main river. The meanders are the bends or turns in a river. The mouth is where the main river enters another body of water. Some other parts of a river are a v-shaped valley, a waterfall, an alluvial fan, a floodplain, levees, an ox-bow lake, and a delta. A v-shaped valley is a valley whose slopes make the shape of a v. A waterfall is a  drop in the bed of a river making the water to drop down vertically. An alluvial fan is a fan or half circle shaped mound of sand and gravel, alluvium. A floodplain i s flat lan...

Image: I took this picture on my phone. Summary Briefly explain the project. Tell us what you learned, not what you did. One specific thing that I learned about was what was a carbon footprint. I had never heard that term before, but know I know what it is , how we reduced it, and why ours was reduced. A carbon footprint is how much carbon is produced by transporting an ite m from one place to another. All of our materials are manufactured inside the U.S.A., so it couldn't travel by ship and it would probably travel by train because all the products are in the same country, but not state. Freight trains emit less carbon dioxide because they can travel about 400 miles on a gallon of diesel while a truck would only travel around 150 miles on a gallon of diesel. Since a train consumes less gas than a truck while traveling the same distance the train would generate less carbon dioxide. Reducing your carbon footprint help...

Image:  commons.wikimedia.org Summary: My group and I continued to work on our soil research and completed the document. From this I learned a few key things to remember: Soil is composed of organic matter, pieces of broken rock, and minerals It is very difficult to identify different types of soil since the mix with other soils and move. Soil is very valuable even though we don't acknowledge it. We depend on soil for food, clothing, to hold buildings steady, and much more. Soil is eroded by water most of the time. Soil loss can be prevented by planting trees and other plants because the roots help to hold the soil in one place. With the substitute we worked on differentiating examples weathering, erosion, and deposition. Deposition is when soil and pieces of rock are added to a land form or landmass. After that, we were introduced to what are carbon footprint is and how it will be a part of our charity fair projects. First we had to determine w...
