the grand canyon essays

the grand canyon essays We decided, for our Science Project, that we would learn about the Grand Canyon and its layers. It is located in Arizona and is one of the greatest natural wonders of the world that is around eighteen miles wide and nearly 280 miles long. The width and depth of the Canyon vary from place to place. At the South Rim, near Grand Canyon Village, its a vertical mile, which is about 5000 feet from rim to river. The width of the Canyon at Grand Canyon Village is 10 miles from rim to rim; though in places it is as much as 18 miles wide. Another way to look at the enormous size is by the time a trip takes. From the bottom of the Canyon and back on foot is a two-day journey. Rim-to-rim hikers generally take three days one-way to get from the North Rim to the South Rim. A trip through Grand Canyon by raft can take two weeks or longer and experienced backpackers have spent weeks in the more remote areas of the Canyon. In 1975 the park was nearly doubled in size by the inclusion of Grand Canyon National Monument and Marble Canyon National Monument and portions of Glen Canyon and Lake Mead national recreation areas. The effects of tourism and federal water management policies led the government to take steps to protect the canyons environment during the 1990s. In March 1996 a controlled flood through Glen Canyon Dam was generated as a way to re-create natural spring flooding through the canyon. The results of this led to a new water-management plan. This plan incorporates flooding to restore the canyons natural ecosystems, which had been changed by the construction of Glen Canyon Dam in 1963. In 1997 the government restricted small planes and helicopters from flying over the canyon and was considering other ways to limit the effects of tourism on the park. The sites of the park are incredible with its beauty and mystery. One of the main attractions is the Colorado River, which is about 242,000 square miles of land ranging fr...

Incomplete Parallels

Incomplete Parallels Incomplete Parallels Incomplete Parallels By Mark Nichol In each of the following sentences, an associated pair of phrases are not optimally stated and organized to make their relationship clear. The discussion after each statement proposes a solution, which follows in each case. 1. Follow with user support and usage monitoring to ensure a smooth transition and an optimal user experience during and post-implementation. In this sentence, during and the prefix post share implementation (and post should be directly attached, with no hyphen), but a preposition and a prepositional prefix cannot share a root word, so replace post with a distinct preposition: â€Å"Follow with user support and usage monitoring to ensure a smooth transition and an optimal user experience during and after implementation.† 2. Millions of Americans, including younger citizens, recent immigrants, and those who do not use credit actively, have a limited or no credit history. The parallel structure of â€Å"a limited or no† is not erroneous, but the idea is more clearly communicated with more complete wording: â€Å"Millions of Americans, including younger citizens, recent immigrants, and those who do not use credit actively, have a limited credit history or none at all.† 3. Such programs should be based on a clear understanding and an evaluation of potential threats of data loss.   Understanding cannot share a preposition with evaluation, because the article an grammatically partitions the two nouns. (An cannot be omitted, because doing so will imply that clear applies to evaluation as well as to understanding.) Assign understanding its own iteration of of, and, to provide further clarity, treat the corresponding phrase as a parenthetical: â€Å"Such programs should be based on a clear understanding of, and an evaluation of, potential threats of data loss.† Want to improve your English in five minutes a day?
