Questions
1: How many earthquakes occur every year around the world?
2,000
2: What is the Tectonics Theory? Explain.
The surface of the Earth is not fixed, it is always moving because of tectonic plates.
3: Where do the Tectonic forces originate?
Originate deep in the Earth.
4: What are Earth’s 3 main layers?
Core, Mantle, Crust
5: Where is Tectonic activity concentrated?
Concentrated in the upper 700 km
6: What is the Lithosphere? Where is it located?
The outer mantle and the crust, it encases the entire earth
7: What is the Asthenosphere? Why is it important to plate tectonics?
The Asthenosphere is the mantle, it can flow so that the plates on top can move
8: How fast do plates move (average?)
About the same speed that fingernails grow
9: What are the 3 types of plate boundaries?
Divergent, Convergent, Transform
10: What happens at Divergent Boundaries? Where are these mostly located?
At Divergent boundaries the plates pull apart, there are frequent earthquakes here. These boundaries are found in the ocean.
11: What kind of rock is Oceanic Crust made of?
Basalt
12: What happens at Convergent Boundaries? What is often formed? Explain.
The plates colide together, mountains are usually formed at these boundaries when the plate buckles.
13: What is Granite? Where is it found?
Granite is made of magma formed from melting plates, it is found are the edge of continents.
14: What happens at Transform Boundaries? What is special about transform boundaries?
The plates here slide across each other, at transform boundaries no magma is formed.
