1: How many earthquakes occur every year around the world? 2000 strong quacks occur around the world.
2: What is the Tectonics Theory? Explain. Earth is a changing motion. Mountains fall, ocean floor opens and closes.
3: Where do the Tectonic forces originate? Tectonic forces originate deep within the planet.
4: What are Earth’s 3 main layers? Central core, thick mantle, and very thin outer crust.
5: Where is Tectonic activity concentrated? Tectonic activity is concentrated in the upper 700 km of the planet.
6: What is the Lithosphere? Where is it located? Lithosphere is the outer mantle and the crust fused together. It is located 100 km inside the Earth.
7: What is the Asthenosphere? Why is it important to plate tectonics? It is the soft layer of the upper mantle. Asthenosphere lets heavier plates float right on top of it.
8: How fast do plates move (average?) It moves as fast as a growing fingernail.
9: What are the 3 types of plate boundaries? Divergent, convergent, and transform plate boundaries.
10: What happens at Divergent Boundaries? Where are these mostly located? Magma flow through cracks in the ocean floor and create new crust, as well as basalt. It is located in the bottom of the ocean.
11: What kind of rock is Oceanic Crust made of? They are made of basalt.
12: What happens at Convergent Boundaries? What is often formed? Explain. Crusts collide within each other. It either creates a mountain, or a trench. Depending on the land surface.
13: What is Granite? Where is it found? Granite is a crystallized rock, and is found in the continental plates.
14: What happens at Transform Boundaries? What is special about transform boundaries? Plates slide past one another and rocks get either crushed and turn into little rocks, or just turn to dust. There are sometimes in which Transform Boundaries could release an earthquake,which runs around the crack below the ocean.
