Which of the following can be inferred from the passage regarding the geologic changes that occurred during Ordovician period? The dry mountain ranges of the Western United States contain rocks dating back to million years, Line to the Ordovician period, and teeming with evidence of tropical marine life. This rock record provides clues about one of the most significant radiations periods when existing life-forms gave rise to variations that would eventually evolve into entirely new species in the history of marine invertebrates. During this radiation the number of marine biological families increased greatly, and these families included species that would dominate the marine ecosystems of the area for the next million years. Although the radiation spanned tens of millions of years, major changes in many species occurred during a geologically short time span within the radiation and, furthermore, appear to have occurred worldwide, suggesting that external events were major factors in the radiation. A They were more drastic than those associated with other radiations B They may have created conditions favorable to the evolution of many new life-forms C They may have caused the extinction of many of the marine species living in shallow waters D They may have been a factor in the development of new species adapted to living both on land and in water.

The state has 12 geomorphic “earth form” provinces. These boundaries are defined as areas that have consistent climates and topography, which in turn influence the animals and plant species found in the vicinity. The Sierra Nevada mountain range is approximately miles long and 50 miles wide. The range is composed of granitic rocks know as batholith. In geological terms, the Sierra Nevada range is very new and is still rising above the central valley below.

It is estimated that the majority of the range has been uplifting for the last million years. However, most of the mountains were created in the last three million years. The majority of the uplifting is occurring on the eastern slopes with the top of the old granitic rocks located on the western slopes. Mount Whitney is tallest peak 14, ft in the Sierra Nevada range and it is the tallest mountain located in the lower 48 states.

Most of the vegetation on the Sierra Nevada Mountains is found on its western slopes. This is because the majority of the rainfall is wrenched from the clouds before it reaches the eastern side of the mountains. As the weather fronts, from the Pacific Ocean, hit the Sierra Nevada they must rise to clear the range. As the air masses rise they condense and allow precipitation to fall on the western slopes.

Studies involving the geology of the Valley have been undertaken periodically over a period of nearly years. One of the first of these was published by University of Virginia geologist Henry Barton Rogers in Rogers, who subsequently left the University to found the Massachusetts Institute of Technology, was a keen observer and first described many of the rocks and other geologic features which are available for our study today.

Following Rogers’ work many studies of the geology of Rockingham have been undertaken. Some of the best known are those by Butts , Brent , and Hack Recent interest in potential oil and gas deposits in the county has brought in geologists from as far away as Texas. These geologists using space age technology should provide even greater insights and clues to the local geologic past in the months and years ahead. This varied landscape results from a combination of three factors: the distribution of the different rock types, the geologic processes of folding and faulting which have deformed these rocks, and lastly the long period of erosion which has worn this area down to its present landscape.

Weathering and erosion are the great sculptors of the earth’s surface. These processes working over millions of years on rocks of differing resistance are responsible for the landscape we see in Rockingham County today. Figure 1 shows that Rockingham contains four major topographic features: the Blue Ridge Mountains on the east, the Massanutten Mountain in the center, the western ridges Allegheny Mountains , and the Valley Floor. Although these mountains which reach an elevation exceeding feet at many points, appear to be separate features, geologists consider all of the mountains in Virginia to be part of the Appalachian Mountain system.

These volcanoes form part of the Northern Cordilleran Volcanic Province , the most volcanically active area in Canada. The first event began million years ago when a group of active volcanic islands approached a pre-existing continental margin and coastline of North America.

The final event began when the Farallon Plate continued to subduct under the new continental margin after the Insular Plate and Insular Islands collided with the old continental margin, supporting a new continental volcanic arc called the Coast Range Arc about million years ago during the Late Cretaceous period.

One of the major aspects that changed early during the Coast Range Arc was the status of the northern end of the Farallon Plate, a portion now known as the Kula Plate.

Rising out of the California desert near Mojave, California, are the Tehachapi Mountains – a rugged chain of wind swept hills. Up until , this land was used almost exclusively by local ranchers for grazing beef cattle. But, in a raging December blizzard, a dedicated band of men and women threw the switch and fed the first wind-generated electrical power into Southern California Edison’s grid.

That single event drastically changed land use patterns in the Tehachapi ‘s. Western Mountain Initiative – Background.

These early artists drew human and animal figures, sun circles, stars, and other more abstract designs.

Rock art is generally divided in two categories: carving sites petroglyphs and paintings sites pictographs. These date from to years ago and are typical of the Fremont and Barrier Canyon style found in this area. In time their mortars filled with sagebrush and blowing dust, and nothing was left that could turn to rust.

Ancient Peruvians created geoglyphs like the Nasca lines by moving stones to define edges of the lines, and then scraping the top layer of earth between the edges to reveal lighter soil beneath.
