Erik Vargas 11/7/2017 Period 1 Water Erosion Purpose The purpose of this lab is to examine the streamflow and how it removes soil from the banking over time. Background Information “Water erosion comes in several different forms with various causes. No matter the differences, we humans can have a large impact on our water quality and erosion rates. While the causes of erosion by water are generally natural, we can play a large role in reducing water erosion, and preventing water…

The Pacific Northwest was once full of an abundance of untapped resources, it was barely populated and was the definition of a hinterland. As the Pacific Northwest started to become known and resources started to become majorly exploited and shipped, we slowly become what we are now, not a hinterland. After all the overuse and misuse of the land we are not and will never hinterland again. The definition of a hinterland is defined as parts of the country that is less developed and…

Poison Dart frogs A popular poison found in nature is Poison Dart Frogs. These frogs live in rainforest habitats in Central and South America and some in the Hawaiian Islands. The name Poison Dart Frog is a name of a group of frogs in the family dendrobatidae. The frogs are mostly bright colored and are diurnal, which means they come out during the day and sleep at night. As usual, Poison Dart Frogs have a delivery system. The article, Poison Dart Frogs, by Vera L. Figueiredo says “The toxins…

It is a beautiful day in Utah at the Timpanogos Cave National Monument. I have packed a backpack of water, snacks, and a flashlight. After double checking to ensure I have my Cave ticket to tour the inside of the cave, I start the trail. After passing the Visitor’s Center I come to a talus slope. A talus slope is a pile of loose rocks that have collected at the bottom of a mountain, cliff, or any high point. Looking at the walls around the area I can see how erosion has weakened the walls near…

A common refrain in 1960 was "Lake Erie is Dead." In the 1960s Lake Erie was terribly polluted. We cleaned it up, but it’s polluted once again. Lake Erie contained increased levels of phosphorus and nitrogen, which contributed to eutrophication, (a process that encourages the development of algal blooms). Since the 1960s Lake Erie has had many problems with algae. Waste water from the sewers also made their way into the lake, as this was happening factories were dumping pollutants into the…

one of the things that I learned more about was the problem with surface runoff of fertilizers and how it interacts with herbicides. The lab showed the participants on a small scale how eutrophication occurs and how it doesn't take a long time for algae to take over an area. Nitrogen and Phosphorus are usually found in fertilizers but not always at the same time. A study done said “ Concentrations of phosphorus and nitrogen in surface waters are being regulated in the United States and European…

In the Florida Everglades ecosystem, Phosphorous is the main nutrient that the South Florida Water Management District is attempting to control. Phosphorous is the same nutrient that is a contributing factor to the algae problem in Lake Erie. In South Florida, the main source of drinking water stems from underground aquifers made of porous limestone, that is refilled via the everglades(NPS,2016). In our region, the main source for drinking water for cities, stems from Lake Erie. Thus,…

Egypt receives less than 80 mm of rainfall a year, and only 6 percent of the country is arable and agricultural land, with the rest being a desert. This leads to excessive watering and the use of wasteful irrigation techniques such as flood irrigation an outdated method of irrigation where gallons of water are pumped over the crops. Desertification is a land degradation problem of major importance in the arid regions of the world. Deterioration in soil and plant cover have adversely affected…

This research proposal seeks to test the hypothesis that pesticide run-off from agriculture, even in small amounts, can have a devastating impact on the aquatic ecosystem, in particular that of Daphnia.  For years, pesticides have been known to have devastating impact on the ecosystems surrounding the agricultural centers they are used in. On a regular basis, run-off from farms that utilize both fertilizers and pesticides can seep into the watershed and slowly trickle into bodies of water…
