a.
Introduction:
The Lake Mead is the largest reservoir or storage of water in the United States with a very high capacity. The Lake has a length of 120 miles, depth of 532 feet and the surface area of 247 square miles. Lake Mead gives power and water to the people for over a large area because of high water capacity.
b.
To determine:
The changes that take place in Lake Mead since the year 1985.
Introduction:
The plate boundaries undergo more damage during the shifting of the tectonic plates. The pulling, colliding and shifting of the layers below the Earth’s crust can bring about more alterations in the geology of the plate boundary whereas, the interior of the plate experiences lesser fluctuations in the geological structure due to plate shifting.
c.
To determine:
The possible reason for the changes.
Introduction:
Lakes are small water bodies that are usually formed when the water accumulates in large craters. The lakes have abundant aquatic biodiversity and serve as a source of water for large human habitats. The lakes are also present in the forests and are the sole source of water for the animals living in the forests.

- Cronon’s Research on Wilderness – Consider Cronon’s study of wilderness, as discussed by Kanazawa (2023). In what ways, if any, would it have been appropriate for Cronon to have used quantitative methods in his study of the concept of wilderness, and to what end? Why were qualitative methods particularly appropriate for the study, given the nature of his research topic? 150-200 words response to the questionarrow_forwardConsider Cronon’s study of wilderness, as discussed by Kanazawa (2023).

- Part 1: A completely saturated sample of sandstone has a bulk density of 2.61 g/cm³, an effective porosity of 10 percent, and a total porosity of 12 percent. Determine the density of the solid phase (i.e., the density of the mineral). Part 2: One cubic meter of quartz sand has a dry mass of 2,320 kg. a) Calculate the porosity of the sand. b) Calculate the mass (in kg) of the sand for the following degrees of saturation: 25 percent, 75 percent, 100 percent. Part 3: A sample of quartz sand has a dry mass of 753.7 kg and a volume of 0.36 m³. a) Calculate the porosity of the sand. b) Calculate the mass (in kg) of the sand assuming a degree of saturation equal to 62 percent.arrow_forwardWhat is an oxbow lake and how is it formed?arrow_forwardFor the past 3 million years the earth has experienced glacial-interglacial cycles at regular intervals that coincide with the Milankovitch Cycles. Please briefly describe the three Milankovitch Cycles and their timescales. What is the leading theory for why the timing of glacial-interglacial cycles is connected to these Milankovitch Cycles?arrow_forward
