exploited. There are several problems that can result from over exploitation of aquifers. Subsidence is a problem that occurs from groundwater extraction in unconsolidated aquifers. An unconsolidated aquifer is composed of porous gravel‚ sand‚ and silt. When to much water is removed from this kind of aquifer‚ the unconsolidated materials settle causing the ground to sink and the ability of the aquifer to replenish itself is permanently removed or reduced (Aquifer‚ 2007). Salt water intrusion is another

I interviewed a friend who was involved in engineering the system to be installed in a hospital and there’s a lot more to it than I first expected‚ I never really thought of how complicated it actually was and how much water that involved. Most companies involved in these commercial jobs are

They also built irrigation systems made up of weirs to raise the water of the river‚ dikes to protect against floods and silt to clog the canals. The Sumerians survived for over a millennium‚ and their spoken language vanished without a trace. But their lasting contributions to humankind like the wheel‚ the sail‚ and the plow live on.

Plate tectonics are responsible for many of Earth’s natural occurrences. From volcanoes to earthquakes plate tectonics play are large role. Another natural occurrence that is not is discussed as much as volcanoes and earthquakes is the formation of sedimentary rock. Plate tectonics also plays a major role in the formation of this type of rock. Plate tectonics is a term that is used to describe how the different plates that make up the Earth move and the reactions that occur as they are moving

Fossils Fossils are the remains of ancient organisms‚ usually animals and plants but there are also minute bacteria and occasionally fungi. They are preserved by natural processes of burial. Most are entombed in sediment i.e. mud‚ silt or sand which with time transforms into a sedimentary rock such as sandstone. Rarely‚ fossils are enclosed in ash erupted from volcanoes‚ resin that oozes from trees and hardens into amber‚ or natural tar seeping from the ground. Normally only the resistant hard

Flooding of the rivers during the monsoon season causes enormous hardship and hinders development‚ but fresh deposits of rich silt replenish the fertile but overworked soil. The rivers also drain excess monsoon rainfall into the Bay of Bengal. Thus‚ the great river system is at the same time the country’s principal resource and its greatest hazard.
