Convergent With Subduction Boundary
Core, Mantle, crust. The crust is what allows us to live on earth. The mantle is the middle layer and where the volcanic activity takes place and creates the crust. Lastly the core is the hottest part and is equivalent to the surface temperature of the sun. This is located at the center of the earth
The continental crust is the layer of igneous, sedimentary, and metamorphic rocks which forms the continents and the areas of shallow seabed close to their shores, known as continental shelves.
Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912
Wegener noticed that the continents seemed to fit together. They found the same fossils from the same animal on different continents
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Seafloor spreading is caused by two plates moving apart and this is caused by plate tectonics. Continental drift is also caused by plate tectonics. This means we can say that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and the continents move away from each other.
This helps because this is where hotter material rises and cooler material sinks, so the magma rises and creates new land while the cooler material sinks.
Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of "plates" that move around across the earth's surface.
Transform boundary is when two plates slide past each other, this can create an earthquake. Divergent is when two plates divide from each other, this can create rift valleys. Convergent boundaries are when two plates collide with each other creating folded mountains. Convergent with subduction is just like convergent but this is with one continental crust and a oceanic crust colliding therefore creating a trench or volcanic ranges.
The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.
Divergent- Rift valleys
Convergent- Folded Mountains
Convergent w/ subduction- Trench or volcanic ranges
