After reading this chapter, completing the exercises within it, and answering the questions at the end, you should be able to: Explain the hydrological cycle and its relevance to streams and what residence time means in … Geology-California-Owens Valley. The world's premier escarpments can be found in Africa's famous Great Rift Valley, but Abert Rim may be North America's finest example of an escarpment. Create. STUDY. Gravity. 48 terms. A terrace results from any hydrological or climatic shift that causes renewed downcutting. Edit. II. Search. (In everyday English, we also refer to large streams as rivers and medium-sized ones as creeks or brooks.) Whitney (14,494 ft.) and Lone Pine (~3,700 ft.), a horizontal distance of only about 13 miles. The part of a river that flows into a lake, reservoir or ocean. Valley glaciers carve U-shaped valleys, as opposed to the V-shaped valleys carved by rivers. A meander is one of a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse. Stream channels have four different channel patterns, the shapes they show when viewed from above or on a map.The curviness of a channel is measured by its sinuosity, which is the ratio between the length of the thalweg and the distance downstream along the stream valley.Straight channels are linear or nearly so, with a sinuosity of nearly 1. Magnetism, Terrestrial-California-Owens Valley. Stream Valley DRAFT. GEOLOGY OF THE BASSETT VALLEY AREA By Gary N. Meyer January 23, 1996 Minnesota Geological Survey 2642 University Avenue St.Paul,Minnesota 55114-1057 (612627-4780 Open-File Report 96-3 ... which allowed meltwater streams and mud slides to carry more debris into the valley. The topographic area adjacent to a stream in a valley with little or no slope is called a floodplain. It is produced by a stream or river swinging from side to side as it flows across its floodplain or shifts its channel within a valley. Physical Geology – 2nd Edition. It also makes them longer by eating farther and farther into the uplands where they begin. The bed erosion of the main stream being greater than those of the tributaries, these tributaries merge with the main stream valley. The geology of California is highly complex, with numerous mountain ranges, substantial faulting and tectonic activity, rich natural resources and a history of both ancient and comparatively recent intense geological activity. This type of stress field is common in Appalachian coal fields, where there is high topographic relief and deeply incised valleys. In geology, a valley or dale is a depression that is longer than it is wide. Owens Valley Geology Owens Valley is a deep north-south trending basin lying between the Sierra Nevada on the west and the White-Inyo Mountains on the east. Streams flow downhill due to the force of gravity. Wide valleys. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Stream erosion digs them deeper and wider. I. Kane, Martin Francis 1928-joint author. Outwash, deposit of sand and gravel carried by running water from the melting ice of a glacier and laid down in stratified deposits. In the ACC study area, it is also found in sections of … 2 times. Start studying Geology Chapter 6. 418 CHAPTER 14 Streams and Floods: The Geology of Running Water the term stream for any body of running water that flows along a channel, an elongate depression or trough. ... Geology Lab Final- Sedimentary rocks. It is not about identifying rocks and minerals. The largest particles (sand and gravel) tend to accumulate within the channel itself. 3. The process of stream erosion to create a valley tends to concentrate horizontal stresses beneath the valley axis. Aug 27, 2014 - V-Shaped Stream Valley | figures youthful stage downcutting narrow valleys Geology Chapter 1: Introduction. Template:Other uses A meander, in general, is a bend in a sinuous watercourse or river. Most valleys on earth are the product of streams. V-shaped Downcutting toward base level Features often include rapids and waterfalls. A meander is formed when the moving water in a stream erodes the outer banks and widens its valley and the inner part of the river has less energy and deposits what it is carrying. a year ago. Play this game to review Geology. Rivers. Valleys change and grow over millions of years. During periods when Earth’s climate cools, glaciers form and begin to flow downslope. River terrace, bench or step that extends along the side of a valley and represents a former level of the valley floor. Geology - Geologic time. Stream Valley DRAFT. The cycle of erosion has some influence on the nature of a stream, but there are several other factors that are important. An outwash may attain a thickness of 100 m (328 feet) at the edge of a glacier, although the thickness is usually much less; it may also extend many kilometres in Great Valley and Susquehanna Lowland physio-graphic sections (Figure 9-2; Appendix B). 4th - 6th grade. A) deepen into a bigger and bigger canyon, like the Grand Canyon B) become steeper and discharge increases in the streams C) become narrower but with a lower gradient, entrenching meanders D) become broader and lower gradient A valley is a low area between hills or mountains typically with a river running through it. They busily modify those valleys in the direction Playfair’s Law predicts, but they have not yet reached the point of full responsibility for the valley’s shape. Played 2 times. Calcareous Geology Streams: Calcareous geology (limestone and dolomite) is common in valleys across southern Pennsylvania. Log in Sign up. 2. 13.4 Stream Types Stream channels can be straight or curved, deep and slow, or rapid and choked with coarse sediments. The youthful streams have high sediment loads, and when they flow into the lower-gradient glacial valleys where the velocity is no longer high enough to carry all of the sediment, ____braided____ stream patterns develop, characterized by a series of narrow channels separated by gravel bars (Figure 14.22). Knowing a lot more about geology doesn't really help much. by changingearth. ENVIRONMENTAL GEOLOGY Module 3 - Rivers and Flooding by Annie Watkins. Learn vocabulary, terms, and more with ... in this set (135) Sea level falls or land rises. Playfair’s Law describes the behavior of almost every stream very well, but there are some streams that are confined to valleys that predate them. Often, they take the easiest path, occupying the low V-shaped valleys once carved by rivers. changingearth. The valley’s maximum topographic relief is about 10,800 feet between Mt. Log in Sign up. This page is about physical geology - particularly about valleys. The rock ridge is moving to the right and blocking the stream. Start studying Geology Test 3. 32 terms. stream valleys evolve over time through downcutting, graded streams, lateral erosion, headward erosion, terraces, and insides meanders. Earth Geology Erosion Valley and Stream Erosion Valley and Stream Erosion. Edit. ... Two general types of stream valleys. Streams have a major role in geology. The higher the hill, the more gravitational energy there is to drive the stream. At these places, a number of tributaries having their own points of origin at higher levels, join the main stream. Downcutting, also called erosional downcutting, downward erosion or vertical erosion is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream's bed or the valley's floor. a year ago. The speed of downcutting depends on the stream's base level, the lowest point to which the stream can erode. The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Stream valley floors are underlain by deposits of alluvium, defined as sediment (mud, sand, and gravel) laid down by flowing water. Geography. 12) Over time as erosion lowers the landscape a river valley will typically _____. By eroding sediment from uplifted areas and creating landforms made of deposited sediment in lower areas, streams shape the earth’s surface more than glaciers do, more than waves on a beach do, and far more than wind does. Feb 25, 2016 - V-Shaped Stream Valley | figures youthful stage downcutting narrow valleys Streams sculpt and shape the earth’s surface by eroding, transporting, and depositing sediment. Stream Profile; ... Meandering channels are typically located in flat or nearly-flat valleys or plains. 0. Knowing a little geology is relevant to placer mining and prospecting for gold in BC. Chapter 13 Streams and Floods Learning Objectives. Geology Expert. The streams erode actively while at their higher levels near the places where they originated. Streams erode dirt and rocks, transport the sediment, and redeposit it in new locations, shaping the earth’s surface into a system of stream valleys. 13 terms. Save. 81% average accuracy. The stress field formed beneath stream valleys is called “valley-unloading” stress. Madison_Metherd. Geology Chapter 6. Note: The word stream is used for everything from a small creek to huge river. Madison_Metherd. A) a stream valley, deepened by glacial erosion, that floods as sea levels rise B) a glacier-cut valley that is dammed by an end moraine and a large lake is formed C) a large, kettle-pocked morraine left as an island when sea level rises following melting of the ice Narrow valleys.
