Mother earth has gone through a lot of changes throughout its four and a half billion-year existence. Earth has seen many different climates and many different species. Because of these changes geologists have broken earths history into different time periods. One such time period was the Pennsylvanian time period. The Pennsylvanian time period is a subdivision of the Carboniferous period. The Pennsylvanian period saw the introduction of many different species that are still present today along with a very different climate and different geographical features than are present today.
Before getting into some of the physical features of the Pennsylvanian period it’s important to know exactly when it occurred. There have been some differing opinions as to how long it lasted exactly, but most scientists agree that the Pennsylvanian period lasted for approximately thirty million years. (Kazlev) The Pennsylvanian period is the younger of the two subdivisions of the Carboniferous time period. The Pennsylvanian time period occurred from about three hundred twenty three million years ago to about two hundred ninety million years ago. () The entire Carboniferous period, which lasted for about sixty-four million years, only makes up about 1.6% of the entire geologic time. ()
The climate of the Pennsylvanian period is very different from that of ours today. The climate can best be described as being similar to a rainforest. “The Pennsylvanian was the time of the great ‘Coal Swamp Forests’ which dominated the equatorial regions of the planet.” (Kazlev) There were extensive swampy regions that stretched across countries. Much of the world was underwater and is what allowed some of the species that emerged to be so successful. Even though ...

...ecause of the coal that was produced during this time period it can be debated that the Pennsylvanian period, and really the entire Carboniferous period, is the most important period of time in the earths history. If it weren’t for the coal that was produced during this period many of the earths energy problems would not have been solved yet.
All good things must come to an end however and the Pennsylvanian time period did end. At the end of the Pennsylvanian time period there was extensive climate change and extinctions of some aquatic life. There were less seedless plants and more seeded plants. () Although the Pennsylvanian time period ended there was a lot accomplished during this time period for the earth. Humans today can be thankful for all of the things that happened during this time period because it has greatly helped the success of the earth today.
After the Civil War, business and corporations have expanded significantly throughout the United States. During this time period, known as the Gilded Age, many aspects of the United States were influenced by these large corporations. The Gilded Age was given that name after Mark Twain referenced it in one of his works. In the post Civil War period, big businesses governed by corrupt acts and held power of both the political system and the economy.
(7 There once was an Italian man by the name of Amerigo Vespucci, who sailed the seas and explored South America. And later named America after himself.
There were many economic opportunities in Pennsylvania. The soil was fertile and there was plenty of land. Grain was a big export here and earned Pennsylvania the title as one of the "bread colonies". The water was also very clean, which helped to prevent diseases. The economic characteristics of Pennsylvania helped the economy to prosper.
Uncolonized North America was once inhabited by many organisms that have now become extinct. The extinction of these organisms can be blamed on the over harvesting of valuable resources or the introduction of foreign diseases from importation. One of these extinct organisms was the American chestnut. The American chestnut once inhabited the Eastern portion of North America from Maine to Florida. The great tree was once a dominant species that inhabited the Appalachian Mountains. The tree provided a staple diet to pre-colonized North American inhabitants and the immigrants of Europe. The great tree which dominated the overstory deciduous forest would soon meet its demise from a foreign invader by the mid- twentieth century.
In the late nineteenth century known as the Gilded Age (or the Reconstruction period) and the early twentieth century known as the Progressive era, the nation went through great economic growth and social change. Beginning from the 1870s, there was rapid growth in innovations and big businesses. This could be because there was population growth and when there is population growth, there is a high demand of products and other necessities in order to strive in society. Many immigrants from Europe, mostly from the eastern and southern Europe, and Asia moved to American cities. Additionally, farmers from rural America desired to increase economically in society and since corporations ruled and political problems occurred, they decided to move into the cities. Afterwards, the 1900s started with the dominance of progressivism which many Americans tried to improve and solve the problems that were caused or had arisen because of the industrialization of the Gilded Age. It was basically the time when progressives fought for legislations like regulation of big businesses, end of the political corruption, and protection of the rights of the people: the poor, immigrants, workers, and consumers. Thus, between the periods 1870 to 1920, big businesses had arisen and taken control of the political and economic systems through corruption and innovations. In response, American citizens reacted negatively and formed labor unions and political systems to diminish the power that large corporations had in America.
Catechism, also known as religious instruction, schooling or teaching coexists with historic and present educational systems. Generalizing on this dogma is the idea that historically, education had the jurisdiction to incorporate religious values into a curriculum. Secular education was not a question of right or wrong, but more of a when and how. Individuals like Benjamin Harris subconsciously disguised religious works in the form of education. The New England Primer of 1777 is his most relevant and popular creation. Based off the Puritan religion, The New England Primer of 1777 imbedded many unique religious and educational principles into early schooling. A book consisting
Before this settlement by the Europeans, Indian tribes lived on the land now known as Pennsylvania. Some Indian tribes included Erie, Huron, Honniasont, Iroquois, Leni Lanape, Shawnee, and Susquehannock. Penn was informed of the Indians that lived on the land...
Before we ponder in the exquisite Appalachian cultural practices and beliefs, let us know more about its geographic region. “Appalachia is a 205,000-square-mile region that follows the spine of the Appalachian Mountains from southern New York to northern Mississippi. It includes all of West Virginia and parts of 12 other states: Alabama, Georgia, Kentucky, Maryland, Mississippi, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, and Virginia” (The Appalachian Region paragraph 1) . Appalachia is the name of a Spanish empire that was drilling for gold and plunders (Williams 19). It is considered the second largest mountains of North America (Brescia 40). The Appalachian towns that include the mines have its own fascinating history. Appalachia is a place that you can visit in all seasons and each season has its unique spirit and mood. So, if you are seeking spring break, it would be a brilliant idea to visit the holy Appalachian Mountains to enjoy some refreshing outdoor entertainment and relaxation activities such as, fishing or eve...
Everyday life in the United States is very different today than it was in the 1700's. Life was harder and the settlers did not have nearly as many luxuries as society has today. Some aspects of the colonial times that were different then are today include family, employment, and social activities. Life in the United States in the 1700's was filled with hard work, cooperation, and dedication to one’s land and family.
William Penn was a great human being who went through tremendous hurdles in life, went against his family’s views but had a strong vision and a will to accomplish pacifism in a colony. Creating Philadelphia was a great accomplishment for the years he spent there and the belief of religious tolerance attracted many individuals to practice freely. I am overwhelmed by his actions he took at a young age and his strong will power to accomplish his goal. Even though, his colony negatively transformed after his departure, his vision was to care for the people and to eliminate differences based on ones’ skin, color, gender, or religious beliefs. To conclude, William Penn was a great human being who envisioned something different and tried his utmost best to create a peaceful colony for one to dwell in and allowing religious tolerance.
People in the northern United States during the early nineteenth century wanted to rapidly industrialize and increase the amount of money they were making. The Erie Canal they believed was a great way to reduce the distance and time of shipping goods to the west. They also realized that the canal would probably increase their markets, which would mean a larger profit. The problem with all of this was how people had to destroy parts of nature in order for this to happen. Nathaniel Hawthorne, a prominent writer during the time, described the canal as “too rapid, unthinking advance of progress.” (57) Hawthorne and his supporters were very upset to see how forests and swamps were being destroyed and ruined in order t...
The lives of men and women, women more than men, have changed a lot of the past couple years even decades and more than that. The interconnection of race and gender in the evolving social hierarchy of the early South, Colonial North Carolina, has changed. In Colonial North Carolina the main difference was on how the ways of “ordinary people” interacted with different genders and how race was different between the people of North Carolina. Peoples’ beliefs were the main thing that changed these views, but sometimes it reflected on political beliefs also. Between men and women sex was seen differently. Men and women’s views on sex were far from similar and this has affected their views on race and their views on each other. Views on sex has been
The Virginian Colony was founded in 1607 as the first permanent English colony. The founders name was John Smith. This colony was in the Southern region. Trade and profits were the reason this colony was founded. Many of our countries morals today come from the founding of the Virginia colony.
After the collision of Gondwana and Laurasia and the formation of Pangaea, all was calm, for at least 100 million years give or take. It was the colossal rents that began Pangea's breakup and the start of our world we know today.
