1: How many earthquakes occur every year around the world? about 2,000
2: What is the Tectonics Theory? Explain. A tectonics theory is were the earth is constant. Mountains rise up and then falls down and the ocean opens and closes where new life is living because of the cause of an earthquake.
3: Where do the Tectonic forces originate? Deep within the planet that are the three internal layers. A Central core, a thick mantle and a thin outer crust.
4: What are Earth’s 3 main layers? The Central core, the thick mantle and the thin outer crust.
5: Where is Tectonic activity concentrated? In the uppermost mantle and the crust and is about 700 kilometers of the planet.
6: What is the Lithosphere? Where is it located? The lithosphere is the outer mantle and the crust that are put together to make a rigid, rocky layer. The lithosphere is located in the entire earth but is broken in pieces, or plates that goes up against one other.
7: What is the Asthenosphere? Why is it important to plate tectonics? An asthenosphere is a solid but soft layer on the upper mantle. The asthenosphere is important because it can deform and flow very slowly so the heavy plates can float on top of it and begins to move.
8: How fast do plates move (average?) The plates moves very slowly the average speed that fingernails grow.
9: What are the 3 types of plate boundaries? One is a Divergent, the other one is a Convergent and the last type of plate boundaries is Transform.
10: What happens at Divergent Boundaries? Where are these mostly located? It pulls apart from each other and what it does the lava goes up and creates a geysers with very hot water. It also creates a basalt that is magma.
11: What kind of rock is Oceanic Crust made of? A Basalt
12: What happens at Convergent Boundaries? What is often formed? Explain. Two plates collide with one another. It can also create a mountain by the impact buckles of the edge of one or both plates. Or when bends down into the deep seafloor and creates a trench.
13: What is Granite? Where is it found? A Granite is magma that is formed into melting plates solidifies into granite. Is light colored, low density rock that makes up the continents.
14: What happens at Transform Boundaries? What is special about transform boundaries? The plates slide past another. It can create a linear fault valleys or undersea canyon. Also the plates jump against each other. Also this boundaries is different than the other ones because theres no magma formed and the crust is cracked and broken but not destroyed.
