History and Culture of Coastal Areas

How have the history and culture of coastal areas been affected by there geology?

Our seven continents where once believed to be just one big continent called Pagaea. The continents moved over time this is called the dance of the continents. Seafloor spreading theory consist of the movement of the Seafloor over the years. Under the sea beneath the seafloor is magma and as time passes the magma comes through rift valleys in the floor (deep valleys that run through the mid-Atlantic ridge, the ridge runs right down the Atlantic in the deep ocean). The continents , also considered tectonic plates, are very important to the movement of the continents. There are three different types of plates movement, the movement of the continents moving past each other causing earthquakes, another is when one goes under another, and the last crash into each other. The history of the coastal area is the fossils founded in some of the the continents and not in others. Some cultures will have volcano, earthquakes, or flooding it depends on where you live, For example If you live in Hawaii you will have volcano and earthquakes because you are on an island and the ocean floor is moving, if you live in the middle of a continent you will not get flooding, because you don't live on the coast , most people that live on the coast get a lot of flooding and earthquakes because they are closer to the sea floor movement. Difffrent rocks are also found on the seven continenets Metamorphic, Sedimentary and Ingneous rocks.Ingneous rocks are created by lava when it cools and hardens. Sedimentary is when particles by water flow this is where fossils are found, and Metamorphic is layers built, and the rock forms when pressure and heat become great enough to change.
