What Are Some Examples of Geographical Features

The term geological processes describes the natural forces that shape the physical makeup of a planet. Plate tectonics, erosion, chemical weathering and sedimentation are all examples of forces that significantly affect the Earth's surface and account for its major features. These processes are closely studied by geologists and earth. The fi rst features usually noticed on a topographic map are the area features, such as vegetation (green), water (blue), and densely built-up areas (gray or red). Many features are shown by lines that may be straight, curved, solid, dashed, dotted, or in any combination. The colors of the line Examples of Geographic Isolation.

In this exercise, you will apply the principles of relative age dating and your knowledge of geologic structures (see Chapter 15 of your lab manual) to interpret geologic histories of various degrees of complexity After the Thaw - The Development of Lake Michigan by Todd A. Thompson. The movement of glaciers across Indiana dramatically altered the landscape. Although less dramatic, modern geologic processes continue to shape the land. Three of the more active types of processes are earthquakes in the lower Wabash and Ohio River valleys, stream and river. Geologists use geologic maps to represent where geologic formations, faults, folds, and inclined rock units are. Geologic formations are recognizable, mappable rock units. Each formation on the map is indicated by a color and a label. For examples of geologic maps, see the Utah Geological Survey (UGS) geologic map viewer Estimated to be between 400 and 600 million years old, the monolith measures about 1.5 miles (2.4 kilometers) wide and 2.2 miles (3.5 kilometers) in length. Geologists believe that two-thirds of the rock, measuring some 3.7 miles (6 kilometers), lies beneath the desert floor

The USGS was entrusted with the responsibility for mapping the country in 1879 and has been the primary civilian mapping agency of the United States ever since. The best known USGS maps are the 1:24,000-scale topographic maps, also known as 7.5-minute quadrangles. From approximately 1947 to 1992, more than 55,000 7.5-minute maps were made to cover the 48 conterminous states Silt and soil deposition, as well as volcanic lava flows, are examples of constructive forces. A constructive force increases geological diversity by creating new mountains and land formations in the Earth's crust. Destructive forces wear away geological features. The Hawaiian Islands were forged by constructive forces of underwater volcanoes. The Blue Ridge province is bounded on the northwest by the Great Smoky fault, across which lies the Valley and Ridge province, and on the southeast by the Brevard fault zone, across which lies the inner section of the Piedmont province.The Blue Ridge province is primarily a physiographic designation, and for this reason, many of the rocks making up the western Blue Ridge resemble the oldest. The geological time scale is based on the the geological rock record, which includes erosion, mountain building and other geological events. Over hundreds to thousands of millions of years, continents, oceans and mountain ranges have moved vast distances both vertically and horizontally. For example, areas that were once deep oceans hundreds of. A formation is a rock unit that is distinctive enough in appearance that a geologic mapper can tell it apart from the surrounding rock layers.

The principle of cross-cutting relationships states that any geological feature that cuts across or disrupts another feature must be younger than the feature that is disrupted. An example of this is given in Figure 19.8, which shows three different sedimentary layers A mountain is a geological landform that rises above the surrounding land. Typically a mountain will rise at least 1,000 feet above sea level. Some mountains exceed 10,000 feet above see level with the highest mountain in the world, Mount Everest, rising 29,036 feet. Small mountains (below 1,000 feet) are usually called hills

Geologic age dating is an entire discipline of its own. In a way, this field, called geochronology, is some of the purest detective work earth scientists do. There are two basic approaches: relative geologic age dating, and absolute geologic age dating 1. Symmetrical fold--is a fold with the sides showing a mirror image with respect to the axial plane. 2. Asymmetrical fold--a fold without a mirror image in respect to the axial plane. 3. Overturned fold--a fold in which the axial plane is tilted and beds may dip in same direction on both sides of the axial plane For example, many slides on Puget Sound occur in a geologic setting that places permeable sands and gravels above impermeable layers of silt and clay, or bedrock. Water seeps downward through the upper materials and accumulates on the top of the underlying units, forming a zone of weakness Geology definition, the science that deals with the dynamics and physical history of the earth, the rocks of which it is composed, and the physical, chemical, and biological changes that the earth has undergone or is undergoing.
