Isthmus Of Panama

The Columbian Exchange was one of the most significant periods in the World History. A huge movement of great numbers of animals and plants started after Columbus’s discovery of America in 1492. It was a double-sided exchange between the “New World” of the Americas and the “Old World” of the Afro-Eurasia. The opening of the routes between two “Worlds” distributed a wide range of new crops and livestock. According to many environmentalists, this biological expansion brought a lot of damage to different ecosystems. However, in general, The Columbian Exchange led to the growth of the population. Ships returned to Afro-Eurasia with the sunflowers, tomatoes, and pumpkins. The most considerable organisms, which were brought

According to the standard accepted theory, the Clovis people were the first inhabitants of the Americas. The Clovis people crossed the Beringia land bridge during the period of the last ice age, from there they spread across the Americas through an ice free-corridor. However, recent finding have suggested that the first people did not walk to America but came by boat. This paper will examine evidence found in Haida Gwaii and other sites along North and South America that supports a different view of human migration to the Americas, the coastal migration theory.

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 Geography of Panama and the Panama Canal The Panama Canal is one of the greatest works of engineering and modern achievements of mankind. An all-water passage through the continental divide of the Panama region had been suggested since early Spanish colonial times of the 16th century. Today a canal that was cut through the Isthmus of Panama is a reality. It's presence has greatly affected Panama in many ways, politically, economically, and socially.

Anthropological theories concerning the peopling of North America is a topic that is widely debated. By far, Western scientists seem to agree that: “As a result of the vast amount of water that was locked up in glacial ice toward the end of the Pleistocene era, there was a worldwide drop in sea level of as much as 400 feet” (Sutton 19), creating a land link, known as the Beringia, between Asia and Alaska. Starting from this point about the land link, we find that Elias’s article “First Americans Lived on Bering Land Bridge for Thousands of Years,” is the most agreeable theory about the peopling of North America.

Between 280 million and 225 million years ago, the earth’s previously separated land areas became welded into a landmass called Pangaea. About 120 million years ago, due to the continental drift, this landmass began to separate. It split the old world and the new world apart, which dividing North and South America from Eurasia and Africa. The separation lasted for million years that it fostered divergent evolution. The new world and the old world’s biological evolution followed individual paths, becoming two separate biological worlds. However, after 1492, human voyagers reversed this tendency. In October 1492, Christopher Columbus and his crew landed in Bahamas. After Columbus arrived in

About 225 million years ago, according to the theory of “Pangaea,” the world was once a single supercontinent that contained all the dry land. Approximately 10 million years ago, North America was shaped by the majestic Canadian Shield. About 2 million years ago, in North America, the grand glaciers laid the land of Canada and the United States, southbound as far as from Pennsylvania all the way to the Pacific Northwest. Recently, about 135 million to 25 million years ago, four massive ranges—the Rockies, the Sierra Nevada, the Cascades, and the Coast Ranges, arose in western North America. About 35000 years ago, the ancestors of the Native Americans, the nomadic Asian hunters, first

Florida and Shenandoah National Park have many commonalities as well as differences that makes each of these geologic setting unique. Though North America looks like Florida and Shenandoah National Park never seemed to collide with one another, Shenandoah has a rock record of being about 1 billion years old that constructed the North American continent and a building block that formed the Appalachians through orogenies. Florida falls about 300 million years old with the North American plate, however findings that were part of Gondwana provides evidence of the origin of Florida. With a vast time difference of these rock records, what can be furthered analyzed of what the

The Mesozoic tectonic history of the North American Cordilleran region is very complex and involves:

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

Hildebrand, (2009, 2003) attempts to integrate both observed geologic features (hinterland high grade metamorphism, Laramide basement uplifts, Cordilleran batholiths, regional-scale Neogene extension) and the lack of observed features (large scale strike/slip faults), while matching paleomagnetic data (large amounts of northward motion in the oceanic realm exist with no evidence on land) (Fern Esperanza beetle-Moorcroft, MS Thesis, 2014).

Long before the Europeans discovered the Americas, the North American region went through a lot of geological and geographic changes. Originally there was just one super large mass of land but overtime that land broke apart forming continents. Shifting and folding of the earths crust formed mountains across North America and the rest of the world. One major change that the region of North America went through was during the period of the Great Ice Age. The Great Ice Age took place 2 million years ago. During the Great Ice Age, large glaciers covered North America (along with other continents). When the glaciers disappeared 10,000 years ago they left North America new and transformed. The changes that the glaciers made were forming of lakes,

Geologists believe that between 280 million and 225 million years ago, the earth’s previously separate land areas became welded into a landmass called Pangaea. About 120 million years ago, they believe, this landmass began to separate. As this happened, the Atlantic Ocean formed, dividing the Americas from Africa and Eurasia. Over the course of the next several million years in both the Americas and in Afro-Eurasia, biological evolution followed individual paths, creating two primarily separate biological worlds. However, when Christopher Columbus and his crew made land in the Bahamas in October 1492, these two long-separated worlds were reunited. Columbus’ voyage, along with the many voyages that followed, disrupted much of the biological segregation brought about by continental drift.

The culture and political structures of Panama as we know it today has evolved from an incredibly diverse and interesting history. Geographically, Panama lies on an isthmus, a strip of land that essentially connects the greater landmasses of North and South America. It is believed that volcanic activity in the late Pliocene era closed the former Central American Seaway that had separated the two continents. The climatic implications of this landform are incredible, allowing for the redistribution of oceanic currents and the formation of the Gulf Stream of the Atlantic of today.

This is a good thing about Latin America because it would probably impact the economy if it wasn’t there. It is the Panama Canal. The Panama Canal is a waterway that brings together the Atlantic Ocean and Pacific Ocean. It really helped trade in Latin America. The canal was built by the Americans in 1904 and a lot of leaders took over the project, including John Wallace, John Stevens and George Washington Goethals. The project was finished in 1914 after taking 10 years to build. The Panama Canal is an important feature to Latin America because it is a quicker way to import and export goods or cargo. It made it easier because instead of going all the way around South America you can go through Panama which saves you a lot of time. That means a lot of more ships pass through. If there was no Panama Canal like I said it would take a lot longer to travel to bring stuff somewhere by water. I also think there would be less ships traveling because not a lot of people would like to travel a long time at sea. I also think a lot of people would die because the trip would take so long. That is how the Panama Canal impacted Latin America in a good way.
