Diego, and Orange County. This would get even worse if we let the this lake dry up. The dust from this valley is so tiny that, “you can get thirty sediments in the width of a human hair. They are so small, if you inhale these into your lungs, they can profuse directly into your bloodstream, carrying with them whatever chemicals are attached to the sediment. That would be Cadmium, Arsenic, and Selenium.” (Tim Krantz Breaking Point 00:31:12 - 00:31:40) These microscopic particulates can affect…

In the cross section of the land mass Vicunia there are sixteen identifiable layers. As we reconstruct the history of Vicunia we can also recognise distinct geological events that have occurred, which allow the layers of Vicunia to lie as we now observe them. Many of the layers contain fossils that have been dated to certain prehistoric periods; this allows us to apply a time scale to the deposition and construction of these layers. We can use the principles of geology and the principles of…

available 1,000 years earlier, this is how people came to the New World through a route that was accessible and helped humans live in a vegetated environment (Mandryk et al., 2001). This was proven through different analysis of freshwater to marine sediments and data of the landscape by a hydrographic program (Mandryk et al.,…

A shark tooth is one of numerous teeth in the shark’s mouth. Different sharks can be classified on the basis of the teeth they have and the functions that such teeth perform in consuming their prey. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangle upper, and non-functional. Sharks have a complete set of teeth when they are born. These teeth are modified placoid scales with an outer layer of enamel, dentine and a central pulp cavity; similar to…

Romans were conceded and emphasized practical and aesthetic nature of their technology over the Egyptian or Greek. “All the aqueducts reach the city at different elevations. Six of these streams flow into covered containers, where they lose their sediment. Their volume is measured by means of calibrated scales. The abundance of water is sufficient not only for public but for private uses and applications but truly even for pleasure...compare such numerous and indispensable structures carrying so…

The elements sodium and chlorine show emergent properties, because when sodium is alone it's just a metal and chlorine is a poisonous gas. When you combine the two with an ionic bond the emergent properties are shown, because they come together to form table salt, but on their own this wouldn't be possible. 2.1.2) Yes, even though organisms only require it in small amounts it is still essential because it contributes to the organism's development. 2.1.3) If a person has an iron deficiency it…

returning and recovering. "Even in ideal conditions, about 1/4 - 1/3 of a coral population dies each year from background mortality. They can die from old age, disease, predation, competition with a neighbor, erosion of their skeleton, smothering by sediment, severe coral bleaching, and from…

Irrigation is a main reason why Yuma Arizona is Yuma Arizona. The control of a river has made it easier to farm and farming is a huge part of the economic success the Yuma has. But Yuma hasn't always been a farming phenomenon it needed irrigation to flourish and that took a lot of work and time to become so. Irrigation changed yuma in a lot of different ways whether it be good or bad. For instance when there was a dam made for irrigation purposes, the steamer boat business was…

as a bright red pigment to Palaeolithic painters, this was to decorate caves in spain and France the metal fascinated people because it was a liquid that would dissolve gold. The ancients used in on a large scale to extract alluvial gold from the sediment of rivers. The mercury dissolved the gold which could be reclaimed by distilling off the mercury. In 1848 he miners of the Californian Gold Rush used mercury from the New Almaden Mines of…
