Mississippi River

For the first paragraph we shall have a quick focus on the geological history of the area of Kalamazoo. The main deposits and formations of the Kalamazoo area where formed during the Wisconsin glaciation period. Now the deposits are actually due to two lobes during this period, the lobes are the Lake Michigan and Saginaw lobe. Kalamazoo is actually know as a “reentrant district” due to the presence of two different lobes materials. During the middle of the Wisconsin Ice Age the Lake Michigan lobe was extending southeastward, while the Saginaw lobe was extending southwest. With the meeting of the two lobes an interlobate developed between the terminals of the lobes. It is also thought that the two lobes overlapped each other. With the Saginaw lobe covering the Kalamazoo area first and then retreating while the Lake Michigan lobe then covered the area. There are also some bedrock formations in the area as well, these formations were established during

The Chattahoochee River is located in Georgia and flows southwesterly towards Alabama. Evidence indicates that humans have been inhabitants of the Chattahoochee River for an extremely long period.

The Mississippi River is one of the world’s major river systems not only in size, but in habitat diversity as well. It is the third longest river in North America. It flows 2,350 miles from its source at Lake Itasca through the center of the United States to the Gulf of Mexico.

The Mississippi River is highly regarded as the most important river in Louisiana. One of the lesser known rivers is just as phenomenal, however. The Atchafalaya River (pronounced At-cha-fa-lie-uh), which is adjacent to the Louisianan southern half of the Mississippi River, is so much of a phenomena that the United States Army Corps has been put in charge of controlling the river!

Over the past 10,000 years or more, the Mississippi River has changed its path several times, ranging from the current location of Bayou Teche to today’s route past Baton Rouge and New Orleans. The Atchafalaya River

Mississippi River Delta region over nearly a century from 1830-1930 and beyond, for the tale of man versus Ol' Man River just keeps rollin' on.

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

Running water moves sediment in the processes of erosion and deposition, causing different types of landforms. As you can tell in the picture above, Michigan’s topography plays a huge role on where the faster and slower flowing rivers are located and the transportation of the materials in the water depends on the speed of the rivers. Erosion is the breaking down of those materials by the agent, water. The water can erode the channel laterally and vertically, in the end, making the channel wider and deeper. There are different types of erosion: hydraulic action, corrasion, corrosion, cavitation, and attrition. Hydraulic action (above on the right) takes place at rapids and waterfalls because the force of the water removes rock particles from the bed and banks of the river. A great example of this in Michigan is Canyon Falls on the Sturgeon River. At the waterfall, the water is rushing at a high velocity, especially in the spring, causing rock particles to move downstream, creating a wider and deeper river. Eventually the rivers velocity begins to decrease and particles start to deposit. This could also occur because lack of precipitation or an increase in evaporation. The deposition of materials at different locations of the river that they began changes the shape of the river, and effects Michigan as a whole in the end. The particles can travel all the way to the mouth of the river, in this case, Lake Superior, causing

Although there is no starting or ending point of this cycle, most of the water on the Earth is found in the ocean. When the sun heats the ocean, some water evaporates as vapor into the air and some water turns to vapor directly from its solid form. Water can also be evaporated as it is transpired from plants and soil. Because the atmosphere has cooler temperatures, this water than condenses and it can be moved by air currents as clouds. Particles can fall from the sky as precipitation as rain or snow. Some of this can accumulate into glaciers. As temperatures rise, this condensed snow will begin to melt and flow into bodies of water or into the ground. Most of this water will end up back in the ocean. This process continues to cycle and water changes states and continues moving constantly (The USGS Water, 2015). Because of all of these different forms of water, Michigan has been changed over and over throughout the past millions of years and the land forms we see now were affected by all of the changes and the movement that water goes through.

The long history of the formation of the Great Lakes and Michigan start with the impact of glaciers. Throughout history, there have been four major periods where glaciers moved across Michigan, shaping and forming the land. Every time a glacier

The Mississippi River influences the states of Louisiana in numerous ways. The river can be both beneficial and harmful to the state. It may help with industries, but at the same time it may be harming by taking away from Louisiana’s coastline. While erosion is widely considered to be a destructive occurrence, it does have some necessary features. For example, erosion provides many nutrients for animals living in the water, and it creates new deltas that many animals live in. Since the beginning of Louisiana, the Mississippi River has been a crucial factor in the creation and the development of Louisiana’s economy. It has helped with things like trade and the growth of crops. The Mississippi is also significant in the way Louisiana is shaped

Past 360 million years ago, Kentucky was approximately 10 degree to the south of the equator when caves started to form. Kentucky was also occupied with water containing tiny organism having shells of calcium carbonate. When these tiny organisms died, shells accumulation of these creatures together with calcium carbonate emanating from water, built up more than millions of years such that it was hundreds of feet thick. On top of these formations, fifty feet of sandstone were deposited by another river system. Sandstone and limestone were exposed when the sea level started to fall approximately 280 million ago (Thompson & Thompson, 2003). When rivers that we have today started to form, sandstone topped plateau covered the Green River whereas a low limestone plain extended towards southeast direction (Call,

The extent to which tectonic processes represent a hazard depends upon when and where they are experienced (40)

     Most of the worst earthquakes are associated with changes in the shape of the Earth's outermost shell, particularly the crust. These so called tectonic earthquakes are generated by the rapid release of strain energy that is stored within the rocks of the crust, which on continents is about 22 miles thick. A small proportion of earthquakes are associated with human activity. Dynamite or atomic explosions, for example, can sometimes cause mild quakes. The injection of liquid wastes deep into the Earth and the pressures
