1. The weather in the dry parts of the sahara are very hot during the day. The average tempature in the summer is above 90 degrees F and the average tempature in the winter can range from 50 degrees F to -60 degrees F. There are dust storms that come about very sudenly in the Sahara. The dust storms can damage your eys so, when you are in one you need to protect your eyes. In these dust storms winds can reach speeds that exceed 100 miles per hour. When the dust storms move they leave a small layer of dust on anything the touch.

2. A Tuareg's life might be different from someone who lives on the Nile because the Nile is a source of water, and if you need water you know where it is. Where as if you were in a caravan, like the Tuaregs are, you wouldn't know where the water was, let alone it there was any near by. Also when you live on the Nile you can farm and you are not moving all of the time, but if you are a Tuareg you are traveling for up to 15 hours every day.

3. People living on the Nile react to their enviorment diferently than someone who is traveling on a caravan. If you live by the Nile you probably farm or have a store or something, but if you are traveling with a caravan you travel to different places to colect salt and sell it. So, if you are living on the Nile you are in onw stable place and you know what your surondings are probably going to do, but if you are on a caravan you might not know much about the place you are.

4. Farmers use irigation to get water from the Nile to thier crops. The farmers dig canals that lead from the river to their fields, but the river was not always very reliable because on years when there was a drought the Nile could not supply enough water to the fields. So, now the farmers use the man-made lake called Lake Nasser for irrigation.

5. The dams affect farming by changing the way that farmers irigate thier fields. The dam holds water in a huge man-made lake called Lake Nasser the lake is used year-round to irrigate farms. Using dams to help stop flouding also helped the farmers control how much water they will use, instead of just waiting for the Nile to floud and hoping you get enough water.

6. The land is changing in the Sahel because there is more rain fall but still not very much. So, when the farmers graze their animals they overgraze them and all of the vegitation gets eaten away by the animals and so the land becomes dry and the soil erodes. Also, they cut down trees for fire wood and if their is no tree roots or any vegitation to hold to soil down they will use a lot of soil which changes the land. media type="youtube" key="T9qB68lnndE" height="385" width="480"
