Aswan High Dam

      The Aswan High Dam goes across the Nile River and was completed in 1970. The dam costed 1 billion dollars and is 364 feet tall while 12,562 feet long. The Aswan High Dam has enormous benefits to Egypt's economy. It produces 10 billion kilowatt-hours annually and the reservoir is 300 feet deep and is 14 miles wide, supporting the fishing economy. It does have negative side affects as well. It prevents fertilizing silt from getting to farmers due to the almost complete control of the flooding.

The Shrinking of Aral Sea

     In the 20th century the Aral Sea was the fourth largest sea in the world. In the 1960s the soviet government decided to irrigate the desert region surrounding the sea. This almost immediately showed a decrease of water. With the desert soaking all the water in and most of it getting wasted, the Aral Sea started drastically decreasing in the 1960s. Level of salinity increased from 10 g/l to 100 g/l.

Acid Rain

     Acid rain is precipitation that has polluted chemicals in it. Mostly of it is fossil fuels from power plants, cars, or factories releasing it into the air causing it to cling to rain or snow. Winds can blow the residue to places who don't even have factories affecting the entire world. The acid rain even affects sea life. It goes from lands seeps into the soil and eventually makes it way to the ocean effectively killing off entire species of sea creatures.

The Ring of Fire

     The Ring of Fire is  an area where a large number of earthquakes and volcanic eruptions occur. About 90 percent of the world's largest earthquakes occur on the Ring of Fire. The ring of fire is a result the movements of the lithosphere plates. The ring of fire also holds some of the super volcanoes of the world.


     Monsoons occur in west Africa and Asia Australia. Monsoons are large scale sea breezes which happens when the land temperature is significantly different then the water temperature. These winds bring moist air inland due to pressure differences and causes a lot of precipitation all over the land. Monsoons happen in the summer because the land heats quicker than water causing massive pressure changing bringing wind and moist air with it.
