Surface water

the Pacific in South America from Chile to the south of Ecuador, they are cold and rich in nutrients and generate an ecosystem abundant marine life that explains the fishing wealth of countries like Peru. The cold water is due to the Humboldt or Peru which comes from the Antarctic waters. In its route between northern Chile and Peru it generates, along with circulation of trade winds, desert coastal areas considered among the driest areas of the world.…

of what I can see when I look someone in the eyes. In the distance, thunder echoed, causing people to look around in concern for rain. Dark clouds over looked the town, making little children constantly duck inside whenever they felt a drop of water. There were no stars out tonight, and the moon shone faintly behind a haze of clouds. A gentle breeze swished through the small town, causing smoke from surrounding torches to fly into the faces of unsuspecting people . Soft music filled the air,…

create significant challenges for the air and the water resources. Biodiversity is commonly defined as the variety of all life. It includes genetic, species and ecosystem diversity and all the interactions between them. Biodiversity’s importance is due to its contribution to environmental, economic, cultural and social well-being by providing valuable ecosystem services such as pollination, carbon storage by forests, bio-filtration of water, nutrient cycling, soil formation, erosion…

Introduction The urbanization of a catchment is a drastic change in land use, and has major effects on the hydrological cycle during heavy rainfall events because of its impermeable surfaces (G. E. Hollis). By recording the discharge in a catchment the data can be used to create a hydrograph. It is often useful to analyse a hydrograph because it shows how quickly rainwater moves to the stream channel (Holden J. 2012.) The aim of this study is to compare an urban and rural catchment, and to find…

The beach has three major parts: beach face, berm and back beach. The area above the water, including the intertidal zone, is known as the beach berm. Beach berm can include vegetation, such as trees, shrubs, or grasses. The most familiar characteristic of a beach berm is its type of sand or rock (Marinebio.net, 2014). Along the backshore, accumulations of wind-blown sand may form sand dunes, and when these are sufficiently stable they become consolidated by a characteristic dune vegetation, for…

media is the environmental medium that contains the pesticide. In order for there to be an exposure a receptor, an individual or population, must come into contact with the environmental medium (Simon, 2014). The environmental mediums are soil, water, air, and biota. The concentration of the pesticide present must be determined in order to calculate a dose. Also, with each individual medium there will be a level of variability and uncertainty that must be considered. Contamination…

What the stream team will be doing is going to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics…

result of global warming, there is not a corner of the worlds’ oceans left unaffected by anthropogenic disturbances. The heating of Earth’s surface occurs through a life supporting process known as the greenhouse effect. This is a natural process where heat from solar radiation passing through the atmosphere is absorbed by gases and radiated back to the surface (Bradford A 2014). However, human activities, such as deforestation, industrial processes, and fossil fuel combustion are polluting the…

In figure one, we see the first week of observation in this lab. In jar TO1 there is nothing but the water in it and there is no noticeable particles on the bottom. There is also no particles on the bottom of TO3 as well. However in jars TO2 and TO4 there are particles and this is due to the fact that there is fertilizer in these jars. As seen in figure 1 there is no growth of any microcosms. Figure 2 and figure 3 tell a different story. Figure 2 is a picture from observation week 5 and it is…

Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a mass, largely under the force of gravity, but frequently affected by water and water content as in submarine environments and mudslides When the gravitational force acting on a slope exceeds its resisting force, slope failure (mass wasting) occurs. The slope material's strength and cohesion and the amount of internal friction between…
