end‚ all these thoughts ran through my brain. I felt suffocated under the pressure‚ but I calmed myself down. I tried to kick my feet loose from the seaweed. Once I freed myself‚ I kicked up to the surface of the water. I coughed and threw out the seawater that got stuck up my nose. Before another wave crashed I decide to swim parallel waves‚ as I had been taught. I reached shore‚ and saw Olivia walking frantically to

An aquifer is an underground layer of water bearing rock. Many areas on earth have an underlying aquifer‚ which can supply fresh water through the use of a well. Aquifers were first tapped for water in the early 1900 ’s for irrigation. Aquifers were originally believed to be an inexhaustible resource thus humans began tapping them for municipal and industrial uses as well (Aquifer‚ 2007). Now‚ many countries are over pumping aquifers in a struggle to fulfill their growing water supply demands. For

Iron‚ which has the chemical symbol Fe‚ is an extremely useful metal and the most common element 0n the planet Earth. Here are some of the more common uses of iron in the world today. Uses of Iron * Iron catalysts are used in the Haber-Bosch Process to produce ammonia and the Fischer-Tropsch Process to convert carbon monoxide to hydrocarbons used for fuels and lubricants. * Iron metal is strong but is also quite cheap. Therefore‚ it is the most common metal in use today. Most automobiles

Desalination of Water While renewable‚ the world’s water supply is being depleted faster than it is being refilled. This has caused ¼ of the global economy to be at risk because of non-sustainable water use. A solution to the unsustainable water crisis is desalination. 97% of all water on Earth is non-usable salt water. The other 3% is fresh‚ usable water‚ however ~68% of that water is locked up in glaciers‚ and 30% is stored in underground aquifers. The remaining 1-2% comes from things such as

change is being observed around the world by not just scientist but by all of us. All of the sea levels are rising at a fast pace because of how fast the ice glaciers are melting‚ the arctic sea ice is melting‚ permafrost and expansion of warmer seawater‚ that is also causing serious threats for all sea creatures and which also includes the death of the world’s coral reefs. The warmer climate change can also be held responsible for the extreme droughts that have been happening that causes a higher

is no record of rainwater pollution in Bangladesh. Surface water pollution is very common in Dhaka and is caused due to human activities. The sources of surface water pollution are industrial and urban wastes‚ agrochemicals and sewerage wastes and seawater intrusion. Groundwater contamination is the degradation of natural water quality as a result of human activities‚ and pollution occurs when contaminant concentration levels restrict the potential use of groundwater. Ground water is not directly

responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. /Salt is currently mass-produced by evaporation of seawater or brine from brine wells and salt lakes. Mining of rock salt is also a major source. China is the world’s main supplier of salt.[7] In 2010‚ world production was estimated at 270 million tons‚ the top five producers (in million tons) being China

Green Sea Turtles Green Sea Turtles are very unique‚ kind and harmless creatures. Although‚ some people do not understand their harmfulness. Many people‚ such as poachers‚ want to kill sea turtles for their meat‚ eggs and shell. Fortunately‚ people have started organizations that help and track sea turtles. Green sea turtles‚ also known as Pacific Green Sea Turtles‚ Black Sea Turtles and Chelonia Mydas‚ their scientific name‚ belong to a scientific group called Cheloniidae‚ a group of sea turtles

gradient pushes relatively cool‚ low-salinity water from the Atlantic across the basin; it warms and becomes saltier as it travels east‚ then sinks in the region of the Levant and circulates westward‚ to spill over the Strait of Gibraltar. Thus‚ seawater flow is eastward in the Strait’s surface waters‚ and westward below; once in the open ocean‚ this chemically-distinct "Mediterranean Intermediate Water" can persist thousands of kilometers away from its source.
