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...

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...
The scenario mentioned above was based on the rupture located along the Cascadia fault line. This fault system runs from Northern California to Vancouver Island about 700 miles off the shore (FOX5). Scientists use to believe that the San Andreas Fault was where a large earthquake tsunami would originate, but recently their attention has shifted to the Cascadia subduction zone which is now said to be much more dangerous than previously thought (FOX5). Recent earthquake events have added even more tension and possibility for a large-scale tsunami. On March 10, 2014, a 6.8 magnitude earthquake struck off the coast of Northern California, which put a lot of stress on the Mendocino Triple Junction (Davidson). The Mendocino Triple Junction is where three tectonic plates collide, and is very unstable (Davidson). This junction has all this built up pressure and is about ready to explode. Scientists believe that this junction will be the origin of a tear along the 680-mile long Cascadia Subduction Zone. (Davidson). The disaster that follows will be considered the United State’s largest modern-day earthquake.
Today, it's believed the first coins used and were bronze in West Valley City, around 20017. Coins were employed by Lydia in Asia Minor. The coins of the Lydian were termed "starters" that was a unit of weight. Entrepreneurs were placed having a lion's mind impression and made out of silver and gold metal. Nowadays, as you may think, the coins which can be still outstanding are very useful.

1906 San Francisco Earthquake Jared E. Gatchalian San Jose State University. 1906 San Francisco Earthquake The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damage and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco.
Unobstructed views of the Pacific’s vibrant blue water, unfilled wetlands, open-access to beaches, and agricultural lands that remain untouched are all attributes that make up the iconic, beautiful, and diverse California Coast. The protection and land-use decisions throughout the entirety of the California Coastal Zone is entrusted to the California Coastal Commission (CCC), which is widely considered one of the most powerful land-use authorities in the country.
The Daisy Cave, Channel Islands is an archaeological site where scores of bone fish hooks, over thirty thousand fish bones, and cordage made of knotted grass, possibly used for making fishing nets, have been dated to thirteen-thousand years ago. Daisy Cave is an important site because it provides strong evidence for the use of boats along the Pacific coast approximately ten thousand-five hundred years ago. San Miguel Island lies approximately forty kilometers off the coast of California, which suggests that it has been separated from the mainland for a much longer period of time than thirteen thousand years. In order for people to have occupied the cave at least ten thousand-five hundred years Before Present, they must have used some form of watercraft to reach the island, which supports the Coastal Route
The Pleistocene epoch is a well-known time period thanks to the glorification of now extinct megafauna as well as the proximity to our current epoch. Through the rapid climate changes and glaciation that occurred many times during this epoch, the fauna
In conclusion, the Chesapeake Bay is the largest Estuary in the United States. It is diverse with many different plants and animals. The bay is made up of salinity, temperature, and circulation (“Chesapeake Bay Program”). The Alewife and the Atlantic Croaker are different, unique, and interesting fish with many interesting characteristics. Humans can have a great or terrible impact on the bay by forming groups to help protect the bay, and polluting the bay with agriculture, urban and suburban runoff, and air pollution from all the cars. The Chesapeake Bay has a very big area of information to learn about. That is what makes the Chesapeake Bay such a unique estuary.
Monterey bay is wide at the entrance, but narrows as you approach the town. It has well wooded shores and everything was very green. The...
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

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.
