The term “bathymetry” originally referred to the ocean’s depth relative to sea level, although it has come to mean “submarine topography,” or the depths and shapes of underwater terrain. In the same way that topographic maps represent the three-dimensional features of overland

can be grouped as follows : • Objectives or purposes, • Preliminary investigations, • Methods of site exploration, • Depth and spacing of trial pits and bore holes, • Choice of a method, • Recording of data. The investigation of the geology and previous uses of any site, together with the determination of its engineering, environmental and contamination characteristics is fundamental to both safe and economic development.

ago. The plants were referred by paleobotanists to at least the Tertiary epoch, or the Age of Mammals. "The Laramide group has given rise to one of the two most prolonged controversies in the history of American geology." [C.P. Dunbar, Historical Geology (1949), p. 375.] But the paleozoologists persisted in ascribing the plants to the Age of Reptiles, and finally coerced the botanists into accepting their view.

deposits are mostly a mixture of gravel, sand, silt, and clay (Surficial Deposits of Illinois). The bedrock under my house is the Pennsylvanian-age Tradewater Formation. This contains thick layers of shale and sandstone and a thin layer of coal (Bedrock Geology of Illinois). In my report I made several important findings about the natural resources, natural hazards, human-induced hazards, and plans for future use. Natural Resources According to the United States Department of Agriculture the soil in

Smith received the Roebling Medal in 1982 and in 1998 he organized the National Academy of Sciences Colloquium on Geology, Mineralogy, and Human Welfare. Smith documented more than 400 scientific articles that where published in journal such as Science, Nature, Journal of Geology, and Scientific America.

Abstract Large igneous provinces are conspicuous features of late Phanerozoic geology, and include continental flood basalts, rifted continental margin volcanic sequences and oceanic plateaus. Many large igneous provinces can be associated with mantle plumes. Where plumes ascend beneath spreading ridges, their energy is transformed into a large melt volume, producing over-thickened plateau crust. Comparing the timing of mass extinctions with the formation age of large igneous provinces reveals a

The Formations of Zion National Park Zion National Park, located in southwestern Utah, contains many “strange and remarkable landscapes” as described by the public who first saw paintings of the region in 1903, which then gained the attention of Congress, leading Zion to become a national park in 1919 (Harris et al., 2004). The park contains steep, almost vertical walls of rock cut by the North Fork of the Virgin River. The exposed rocks range from Permian to Cretaceous in age and contain many fossils

from the cementation of sediments that result from the erosion of older rocks. The characteristic feature of sedimentary rocks is their stratification or layering. Examples of sedimentary rock include; chalk, coal, limestone, sandstone, and shale” (Geology Circle, N/D). The disintegration of igneous or metamorphic rocks (and their re-solidification sedimentation) forms these rocks. They form layer-upon-layer in a somewhat horizontal plate. Once sedimentation comes to rest, it may be turned into rock

Earthquakes happen rarely and when they do, they cause a lot of damage to both the geology of the area and the geography. They are the most powerful natural forces that can happen at any time. Geologists and scientists define earthquakes as vibrations of the earth's surface that occurs as a result of a release of energy in the earth's crust. The plates of the earth are constantly moving and small earthquakes can occur more often but they are not felt. When these plates slide past one another or collide
