Biome (Desert)- Climate Affecting Soil And
With reference to one biome that you have studied, account for the type of climate experienced in this biome and explain how this climate impacts on soils and vegetation within the biome. (80 marks) Marking Scheme: Number of aspects discussed: 3 @ 20 marks each 4 @ 15 marks each For each aspect: Identifying aspect 4 marks 3 marks Discussion 8 x SRPs 6 x SRPs Overall Coherence 20 marks graded* 20 marks graded* In this answer, I choose 3 aspects to discuss (1. Climate, 2. Climate’s impact on soil and, 3. Climate’s impact on vegetation). Overall coherence means how well your answer is structured (Introduction, main section, conclusion – well-structured and coherent) and do you keep to the point/ answer the question directly. Introduction: In this answer I am going to discuss the type of climate experienced in the hot desert biome and how this climate impacts on soils and vegetation within this biome. Biomes are classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment. They are a large geographical area controlled by climate. Therefore the climate of a particular region will affect what type of soil is formed in that biome as well as what types of plants (flora) grow there. The hot desert that I have studied is the North American Desert Biome. Body of Topic: A desert biome can be defined as an arid region that is characterised by little or no rainfall, in which vegetation is scarce or absent, unless it has specially adapted. As a result of its location, between 15º and 30º north of the Equator, the climate of the hot desert biome is hot and dry. -

Cordell, University of Colorado, Boulder, CO, and approved October 30, 2009 (received for review June 22, 2009) Our understanding of the initial period of agriculture in the southwestern United States has been transformed by recent discoveries that establish the presence of maize there by 2100 cal. B.C. (calibrated calendrical years before the Christian era) and document the processes by which it was integrated into local foraging economies. Here we review archaeological, paleoecological, linguistic, and genetic data to evaluate the hypothesis that Proto-Uto-Aztecan (PUA) farmers migrating from a homeland in Mesoamerica intro- duced maize agriculture to the region. We conclude that this hypothesis is untenable and that the available data indicate instead a Great Basin homeland for the PUA, the breakup of this speech community into northern and southern divisions Ϸ6900 cal. -

Spatially-Explicit Modeling of Modern and Pleistocene Runoff and Lake Extent in the Great Basin Region, Western United States
Spatially-explicit modeling of modern and Pleistocene runoff and lake extent in the Great Basin region, western United States Yo Matsubara1 Alan D. Howard1 1Department of Environmental Sciences University of Virginia P.O. Box 400123 Charlottesville, VA 22904-4123 Abstract A spatially-explicit hydrological model balancing yearly precipitation and evaporation is applied to the Great Basin Region of the southwestern United States to predict runoff magnitude and lake distribution during present and Pleistocene climatic conditions. The model iteratively routes runoff through, and evaporation from, depressions to find a steady state solution. The model is calibrated with spatially-explicit annual precipitation estimates and compiled data on pan evaporation, mean annual temperature, and total yearly runoff from stations. The predicted lake distribution provides a close match to present-day lakes. For the last glacial maximum the sizes of lakes Bonneville and Lahontan were well predicted by linear combinations of decrease in mean annual temperature from 0 to 6 °C and increases in precipitation from 0.8 to 1.9 times modern values. Estimated runoff depths were about 1.2 to 4.0 times the present values and yearly evaporation about 0.3 to 1 times modern values. 2 1. Introduction The Great Basin of the southwestern United States in the Basin and Range physiographic province contains enclosed basins featuring perennial and ephemeral lakes, playas and salt pans (Fig. 1). The Great Basin consists of the entire state of Nevada, western Utah, and portions of California, Idaho, Oregon, and Wyoming. At present it supports an extremely dry, desert environment; however, about 40 lakes (some reaching the size of present day Great Lakes) episodically occupied the Great Basin, most recently during the last glacial maximum (LGM) [Snyder and Langbein, 1962; Hostetler et al., 1994; Madsen et al., 2001]. -
North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave
North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave http://www.desertusa.com/desert.html In most modern classifications, the deserts of the United States and northern Mexico are grouped into four distinct categories. These distinctions are made on the basis of floristic composition and distribution -- the species of plants growing in a particular desert region. Plant communities, in turn, are determined by the geologic history of a region, the soil and mineral conditions, the elevation and the patterns of precipitation. Three of these deserts -- the Chihuahuan, the Sonoran and the Mojave -- are called "hot deserts," because of their high temperatures during the long summer and because the evolutionary affinities of their plant life are largely with the subtropical plant communities to the south. The Great Basin Desert is called a "cold desert" because it is generally cooler and its dominant plant life is not subtropical in origin. Chihuahuan Desert: A small area of southeastern New Mexico and extreme western Texas, extending south into a vast area of Mexico. Great Basin Desert: The northern three-quarters of Nevada, western and southern Utah, to the southern third of Idaho and the southeastern corner of Oregon. According to some, it also includes small portions of western Colorado and southwestern Wyoming. Bordered on the south by the Mojave and Sonoran Deserts. Mojave Desert: A portion of southern Nevada, extreme southwestern Utah and of eastern California, north of the Sonoran Desert. Sonoran Desert: A relatively small region of extreme south-central California and most of the southern half of Arizona, east to almost the New Mexico line. -

Great Salt Lake FAQ June 2013 Natural History Museum of Utah
Great Salt Lake FAQ June 2013 Natural History Museum of Utah What is the origin of the Great Salt Lake? o After the Lake Bonneville flood, the Great Basin gradually became warmer and drier. Lake Bonneville began to shrink due to increased evaporation. Today's Great Salt Lake is a large remnant of Lake Bonneville, and occupies the lowest depression in the Great Basin. Who discovered Great Salt Lake? o The Spanish missionary explorers Dominguez and Escalante learned of Great Salt Lake from the Native Americans in 1776, but they never actually saw it. The first white person known to have visited the lake was Jim Bridger in 1825. Other fur trappers, such as Etienne Provost, may have beaten Bridger to its shores, but there is no proof of this. The first scientific examination of the lake was undertaken in 1843 by John C. Fremont; this expedition included the legendary Kit Carson. A cross, carved into a rock near the summit of Fremont Island, reportedly by Carson, can still be seen today. Why is the Great Salt Lake salty? o Much of the salt now contained in the Great Salt Lake was originally in the water of Lake Bonneville. Even though Lake Bonneville was fairly fresh, it contained salt that concentrated as its water evaporated. A small amount of dissolved salts, leached from the soil and rocks, is deposited in Great Salt Lake every year by rivers that flow into the lake. About two million tons of dissolved salts enter the lake each year by this means. Where does the Great Salt Lake get its water, and where does the water go? o Great Salt Lake receives water from four main rivers and numerous small streams (66 percent), direct precipitation into the lake (31 percent), and from ground water (3 percent).
