The Five Main Geographic Regions

The Slate Belt bioregion is nested within the Great Valley Section of the Valley and Ridge Province that was formed by thrust and fault folding during the Late Ordovician period through and Late Paleozoic era.(Bailey,1992; Geyer, 1979;Van Diver, 1990). During this time Taconian

4. The Great Ice Age thrust down over North America and scoured the present day American Midwest.

1.The geological and geographical conditions that set the stage for North American history is that the earth formed slowly,10 million years ago North America was sculpted ,and the continent was anchored in a north eastern corner by a canadian shield.Around 2 million years ago the great ice age began,the ice sheets were about 2 miles thick crept from the polar region , in North America the glaciers carpeted most of canada and the U.S., parts of europe,Asia,and the americas werecovered with a blanket of snow.

The Five Themes of Geography are: Location – Absolute points on a map or grid or Relative to where something may be; Place – The physical and/or human characteristics of a locations; Human/Environment Interactions – How humans have impacted the landscape or environment; Relationship between places Movement – How humans interact on the earth (i.e. how they communicate over distance (short or long)) and Regions – a unit of space that has commonalities defined by physical, human and environmental geography. The Explorers of the New World may have not known what the Five Themes of Geography were but they quickly learned. Of the five themes the ones that they all took advantage of was the physical Location and Place as they learned to navigate

Cenozoic sedimentary rocks predominated to the west and east of the central mountain while plutonic rocks predominated in the peninsular ranges. The irregular contact between these geologic regions reflects the ancient topography of the area. The ancient oceanic crustal plate created an archipelago of a volcanic island. The former's subduction created immense volumes of magma. This resulted to the congealation of plutonic rock in the crust. The local rocks that existed before the tectonic forces uplifted, and erosion capped the deeply buried plutonic rocks that formed a steep and rugged mountains coastline, similar to that present one, which in the west coast of south America.

For example, The appalachian Mountains were formed by a massive continental collision over 300 million years ago. According to page 88 in my science notebook, the rocks in the Chattooga River is evidence of the continental collision. Mountains are formed when two continental plates collide, and form the mountains. The Appalachian mountains, were formed during Pangea. The North American Plate and the African Plate collided. When this happened the Appalachian Mountains were formed. These mountains then grew bigger, but as soon as it started growing, it also eroded. Erosion and

The Ozark Mountains are characterized by eroded plateaus caused by the collision of the super continent of Gondwana, which compressed the present continents of South America, Africa, Antarctica and other land masses. These forces uplifted Arkansas with limestone and calcareous rocks such as sandstone and chert. Erosion lowered the surface creating a level plateaus which included: The Boston Plateau, the Springfield Plateau, and the Salem Plateaus. Rivers, over time, cut valleys into the plateaus. Present day Fayetteville-Springdale-Rodgers, Harrison, Mountain Home, Batesville, and Clinton are all cities which are within the Ozark Mountains boundaries.

During the Late Kaskaskia (Cratonic Sequence 3), what type of deposition predominated on the craton?

Predictably, with its abundance of lush green forests, Washington is known as the Evergreen state. It has four main regions that are important, as tourism is very popular in Washington. Also, these regions are very pretty and are perfect places for hiking, camping, and sightseeing. Counting mountain ranges as one region, four main regions cover Washington. They are the Rocky, Olympic, and Cascade mountains, Puget Sound Lowlands, Coastal Range, and the Columbia Plateau. Each one of these regions has unique features and is important to the state in its own special way.

primates were able to migrate from Asia to North America 56 million years ago because of huge volcanic eruptions, which released an ample amount of greenhouse gases leading up to an intense period of global warming. Because of this, the vegetation of North America began to change. The cool forests turned into tropical rain forests who kept their leaves all year round so they can provide food and shelter for these primates, allowing them to migrate to North America. At About 70 million years ago, a piece of earth’s crust under the Pacific Ocean dove down under North America making it rise creating the Rocky Mountains. As the Rocky’s continued to rise, the land under the inland sea was forced up and all of the water drained into what is now

This formation is a very fine grain Mississippian limestone. To test to see if this was the Bangor formation we used HCL and because there was a reaction we know its limestone. This formation could also be described as gray in color as well as an average thickness of 700 feet. We see the Bangor until stop eight, where we see a very different vertical bedding. Also different at stop eight is the outcrop no longer reacts with HCL. From this we gathered that we had moved into the Hartselle formation. In the Hartselle Formation, Mississippian aged sandstones are dominant. This particular stop had a large amount of jointing. After the Hartselle, we figured the Pride Mountain Formation would be next, however at stop nine we see the Maury Formation present. This stop focused on the rock located inside the creek. Because we were unable to go into the creek to get the strike and dips, we once again had to do a projected orientation. Also found on this stop were natural sulfur springs, easy to notice with the smell that it gives off. The Maury formation consist of Mississippian- Silurian aged shale. At the next stop, stop 10, we encounter the Ft. Payne formation. Although this area location was thickly vegetated, we were able to conduct the acid test and saw that the HCL reacts in some places but not all. From this we concluded that this was the cherty limestone of the Ft. Payne formation. The following stop, 12, we went up section and arrived at the Maury Formation once again. At the final stop, location 13, we see Ft. Payne Formation. All of the metamorphism and deformation in the southernmost Appalachians can be related to the movement of the thrust sheets and stacks (Higgins,

The Tuscarora formation is in the Silurian age, located in Pennsylvania, mostly composed of quartzite, and is secondarily composed of sandstone. Its thickness is 150-200 feet and is in the lower part of the Silurian age. The Tuscarora formation is in the Clinton group. One member would be Castanea located at the top of the Tuscarora Formation. The depositional environment is, as we know it, a continental shelf of some sort of marine zone because of sediment structures like fossils and cross-bedding. The Tuscarora formation is mainly non-porous and neither

Each region's environment affect the animals that live there because animals are built for certain environments, for example alligators live in the south east because they thrive off fresh water environments, ponds, marsh, wetlands, lakes, and swamps. They also serve a great purpose to the environment, because they offer more diversity into the ecosystem.

The Acadian Orogeny not only started the mountain building in the region but also brought volcanic activity along and this meant that the rocks in the region now where under a great amount of pressure and extreme amount of heat.

The alpine orogeny is an arcuate mountain chain in Europe that runs across the countries of Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland (Froitzheim et al. 2008) Its length is 1000km, and width falls between 120 and 250km. The Alps are divided into four subdivisions, which include the Central, Southern, Western, and Eastern portions (Figure of map). Two cenozoic basins represent the eastern end of the Alps. The Vienna basin compromises the north while the Styrian basin is in the south, hiding any tectonic units (Froitzheim et al. 2008). East-west orientated valleys that are products of the Tertiary age Periadriatic Fault create the boundary of the Southern Alps from the other subdivisions (Froitzheim et al. 2008). Below the Southern Alps is the Po basin, which is a foreland basin of the Southern Alps. A geographic boundary doesn’t exist between the Southern Alps or the Dinarides, so it is accepted that they are a continuation of the Southern Alps. This is likewise with the Pyrenees south of the Western Alps, and the Jura Mountains North. The north-south orientated fault zone called the Sestri-Voltassio creates the boundary between the Alps system and the Apennines Mountains (Froitzheim et al. 2008). The geographic boundary between the Eastern and Central Alps is drawn from Lake Constance southward to Lake Como. The boundary between the Central and Western Alps is
