The Bay Area is an interesting place with a unique geology and formation. The San Francisco Bay, also known as San Francisco Estuarine, consists of three bays, San Francisco Proper, San Pablo Bay, Carquinez Strait, and has a vast inland river delta. The river delta provides fresh water to the bays. The estuarine system provides food, safety, and shelter to many organisms and animals, including humans. (San Francisco Estuarine Wetlands) Along the bays lie major cities such as San Francisco, Oakland, and San Jose. San Francisco is located on the boundary between two tectonic plates, the North American and Pacific plates. These two plates form a transform fault called the San Andreas Fault and is responsible for producing large earthquakes that shook California (Elder). Mountains on the California Coastal Ranges, Santa Cruz Mountains and the Diablo Range, were formed as a result of the San Andreas Fault(Elder). Thanks to the tectonic plate boundary, San Francisco Bay Area has the most active and complex geology (San Francisco Bay Area National Parks Science and Learning (NPS)). Today, the Bay Area supports millions of people, plants, and wildlife, but in the past, the Bay Area was completely different than the present. Traveling back a hundred million years, one million years, a hundred thousand years, a thousand years, and a hundred years back in time will reveal how the Bay Area has changed through time. In addition to geography, the atmosphere, biosphere, geosphere, and hydrosphere have also changed through time.
Traveling back a hundred million years ago to the mid Cretaceous period, Bay Area did not exist yet. The Bay Area was still in the process of drifting a hundred million years ago. The continents drifted toward their pr...

In Barbara Berlund’s Making San Francisco American: Cultural Frontiers in the Urban West, Berlund explains how San Francisco grew from a young settlement which grew rapidly thanks to in part of the California Gold Rush which took place in 1949. Of course with the growing of this small settlement came it’s conflicts and how it rised to where it stands present day. A primary factor which helped San Francisco flourish a ton was the influence from those who had power and chose what would happen throughout the city, for example the Big 4. Those who were wealthy did not make this city what it is today without the help of people who made up the middle class as well. Every establishment within this city set the social order as to how the inhabitants of San Francisco would go about their life in society.
The Long Point Fault is located in Harris County, which covers 83,450 square miles located with in Houston, Teaxas City Limits. Research specifies that there are three sections of the Long Point fault that appear to be active; some sections of the Long Point fault have averaged more than 2 cm per year of vertical offset over the last 20 years. Evidence of the faults concludes it is a natural fault. The reason for activity is not caused by man, even though man’s activities are not helping the issues, but clearly humans are not the initial cause, biological activity can be in fact an adiitional cause for its movement. A brief description of the type of fault and its relationship with the strata and the faults beneath the Houston area, are at depths of 1,000 to 4,000 m. They have been well-defined through the study of well logs and seismic lines. Studies have resuted in assumuptions that some of these subsurface faults penetrate younger sediments at shallower depths, and contain faults that have of set the present land surface to produce recognizable scarps.

Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...
EPIC is the Educational Participation in Communities. This organization involves students as volunteers in the fight against poverty and social neglect in local communities. The goal is social awareness and student involvement. It says that poverty, neglect, and social inequity are a growing reality for millions of people in America. Families are losing their homes, people can't find good jobs, children go hungry, and education in the inner-city is a disaster. There is a is problem because the public and community programs that serve as a safety net to assist such populations are strained beyond their capacity and are usually understaffed and under-funded. Since they cannot do the job without help, EPIC helps. It recruits college students to do volunteer work in schools, hospitals, community centers, legal aid, probation, youth agencies, and other and public service programs. EPIC volunteers provide thousands of volunteer hours to the community.

In modern times Oakland is known as the main metropolitan city in the East Bay. The city possesses 3 professional sports teams, which have a population of just below 400,000. Oakland is also the 3rd largest metropolitan city in the Bay Area behind San Jose, and San Francisco.( Encyclopedia Britannica ) The city mayor is the ex Governor of California Jerry Brown. Located in Alameda County Oakland’s area consists of a total square mileage of 78.2 miles, of which 56.1 miles is land, and the latter consisting of water.( Encyclopedia Britannica ) Oakland also possesses the 3rd largest seaport on the west coast.

This paper introduces the environmental concerns of the loss of coastal wetlands. The paper will discuss the significance of wetlands and the devastation that is occurring because of human activity. Wetlands are an essential element of our environment both ecological and societal; conservation will be essential for the preservation of these precious ecosystems.
California, a state located on the West Coast of the United States is the most popular state. Its the third largest state by area. California borders Oregon to the North, Nevada to the East, Arizona to the Southeast, and the Mexican States of Baja to the South. On 1850, September 9 California became the 31st state of the United States. California became the 31st state in the Union even though it hasn’t even been part of the United States for less than 2 years.
As a Californian learning about the state’s government, it is essential to know how our state came to be today. On that note, I learned that a majority of the beginning of California’s history was under the ownerships of Mexicans. Some famous contributors that lead to California’s success today is due to Juan Rodriguez Cabrillo, Gaspar de Portola, and Sebastián Vizcaíno. This can date back to 1542 where Spain claimed California. However, as the US began to experience the Manifest Destiny, the need to spread from sea to shining sea, Americanizing the territory lead to officiation of California as the 31st state, under the Compromise of 1850. Of course, there has already been settlement in California by the Native Americans that dates back to
