    that will work to find the age for that fossil. As well as the many terms that goes in the processes for dating fossils. Relative dating does not give an actual date for the fossils. Relative dating is used to organize geological events, and the rocks they leave behind in a sequence. A geological event is basically a severe natural event that happens in the crust of earth that is normally harmful like an earthquake or a volcano . The method of reading the order is called stratigraphy…

    exposed rock material has a visible reverse fault, and is heavy faulted/folded. Visible soil, and vegetation growth on exposed section of the formation. Visible iron oxide staining from fractures in the section both natural, and manmade. Alternating material layers light grey to dark grey in the formation, and thick bands. 0 to 3feet of the section is composed of light grey, and soft material. The bottom facie was a small section of laminated layered shale. 3 feet to 6 feet of the exposed rock…

    1. Short summary of the history At 145 ± 4 to 66 million years (Ma) ago, Cretaceous period was the last period of the Mesozoic Era, right after Jurassic period and followed by the Paleogene period of the Cenozoic Era (International Commission Chart, 2014). 'Creta' in Latin means chalk and this is due to the large amount of calcium carbonate deposited by shells of marine animals thus resulting in large quantities of chalk (American Geological Institute, 1972). The shifting of continents as the…

    tectonic plates and sediment accumulation under the Earth’s surface. The Appalachian Mountains reveal subsidence belts, faulted marine sedimentary rocks and other geologic rocks in these tectonic settings. The Basin exists in the northeastern states of North America. This large rock formation exhibits collisional tectonics with modern time development of shales. This mature rock formation has the ability to contain an abundant amount of oil and gas. This environment has been a crucial aspect for…

    will be used to represent the sedimentary rock. The goal is to see if different amounts of alum powder will affect the amount of crystals that grow. In this experiment, the groups’ hypothesis is the more alum powder in the solution, the bigger crystals will form. A geode is a “mass of minerals within a rock that can take thousands of years to form” (Steve Spangler). The word geode is from the word Geoides, which is considered “Earthlike” (Wonderopolis). These rocks form geodes when…

    stones, sliding rocks, moving stones, and moving rocks are a topographical marvel where rocks move and write long tracks along a smooth valley floor without human or creature intercession. Stones with unpleasant bottoms leave straight striated tracks while those with smooth bottoms have a tendency to meander. Stones once in a while turn over, presenting another edge to the ground and leaving an alternate track in the stone's wake. Trails contrast in both heading and length. Rocks that begin…

    The Western Cordillera is found standing along the western edge of the continent. Made of ranges and ranges of mountains separated by occasional plateaus and valleys. Many provinces found in this region are British Columbia, Yukon Territories, Southwest Alberta, and parts of Northwest Territories. The mountain ranges found here are not as old as the other regions, as they are not yet rounded hills. These mountains occurred when the North American and Pacific plates collided, that spans…

    known fossil diatoms are from Lower Cretaceous in age, although fossil record is limited. Diatoms might have a much longer history, but because of their mineral instability under lithostatic pressure, well-preserved diatoms become rarer with older rock strata (Harwood and Nikolaev, 1995). Globally Cenozoic marine successions are rich in diatoms, and its biostratigraphy is based on regional and global first and last occurrence of unique, short-lived diatom with widespread…

    lay large 60 degree a ngeled slabs of rock known as the Flatirons. Over millions of years sediment become compressed into these layers of rock. Clues to what may have caused the tilted sedimentary layers are the darker rock at the bottem called granite, which has no layering like the rock on top of it. The garnite full of menerals showing signs of magma, from a liquid rock. From class I know that magma is usually found deep within the Earth. But this rock has been pushed up causing a tilting…
