Tectonics

major field until World war II, when the sea floor was mapped out in detail for submarines revealing a mid-Atlantic underwater mountain range, and a rift which started the theory of Plate Tectonics. Plate tectonics are used to explain the forming of mountains and even continents after the Pangaea. Plate tectonics explains that continents could have broken up, but there are 2 major theories on how. Catastrophist’s believe that a series of catastrophes caused things like plates, and the splitting…

earth isn’t round. Newton's research showed that inside the earth there are multiple layers. Later scientists discovered that the very first layer, the crust, is made out of plate tectonics. All the different phenomena that we see on Earth, such as earthquakes, volcanoes, and landforms, are caused by the plate tectonics. In order to understand the layers of the earth one has to understand how the earth was formed. Earth started out as planetesimals, small bodies from which a planet originated…

For my “specialty,” I had seismology. Seismology is the branch of geology that studies earthquake behaviors. In this case, I had to deal with earthquakes and the movement of Earth’s tectonic plates. My plan was to look at where the map had different elevation patterns, so I can differentiate them into groups. I found 3 different categories, and identified them as Type 1, Type 2, and Type 3. My first category is a blue (X) to represent the boundaries outside the Pacific, South American, and…

Plate tectonics is a theory about how the plates are constantly moving on top of a layer of magma that is constantly taking in old crust to recycle it this constant movement causes earthquakes, tsunamis and other geological events. The movement of the Pacific and North American plates cause the old sea floor to be replaced by the now wider North American plate. Also with the movement the continental plate was stretched as the Pacific plate pulled the continental plate to the northwest which…

The Caribbean tectonic plate has a wide variety of height and depth within its borders. While all the land and islands are quite tall, the middle of the plate, that is mostly sea, is much more deep in some areas than others. Around the Yucatan Peninsula, Central America, and all the islands are gradual slopes that gain more depth the further from land-above-sea-level you get, however, from Honduras and Nicaragua to Jamaica, where there should be deeper sea, there is quite a lot of height but…

Mid ocean ridges is the creation of the motion diverging plates and it is an underwater mountain range which are formed by plate tectonics. It consist of mountains linked together, having a valley running along the spine, and its known as an oceanic spreading center which is in charge of the seafloor spreading. New seafloor is being produced when convection currents rise in the mantle layer which is under the oceanic crust, it then create magma that cools down into basalt where two plates is…

peanut butter and jelly or rice and beans. Where there are volcanos there are usually tectonic plates beneath them either pushing against or pulling away from one another. Take for instance the Cascade Mountain Range in Northern California and stretches through Oregon and into Vancouver, British Columbia and sits northeast of the San Andreas Fault line that runs 750 miles through California. This fault creates the tectonic boundary between the Northern America and Pacific Plates. The three types…

The continents were once part of a single landmass called Pangaea but then a force caused the continents to move them apart. The first piece of evidence used for this theory was that Africa and South America fitted together like it was a jigsaw puzzle. The next piece of evidence was that in South America and Africa there are fossils found in rocks of the same age and type. Additionally, in those two landmasses, there are corresponding early mammal fossils found. Again, there are identical…

The plate tectonic theory says that there are plates covering the outer layer of the Earth and that they have been moving around as time goes on. It says that the Earth was once made up of a supercontinent, called Pangea, and as time went on the plates started to shift and eventually became what they are today. Several different scientists over a course of over 20 years have used each other’s work and pushed our scientific knowledge to develop the theory and give us our four different boundaries…

Plate tectonics is a scientific theory that describes the large-scale motion of Earth’s Lithosphere. The theory was believed to be developed around 1912 by Alfred Wegener. Wegener introduced the fact that all of today’s continents were once a large supercontinent (Pangea) and how they slowly drifted to their present positions. This idea was developed by simple observations such as the fact that the African and South-American coast lines fit together like pieces of a puzzle and that fossils and…
