Tectonics

Question 1

What are the four different layers the earths structure is divided in ?

Answer 1

Inner core
Outer core
Mantle
Crust

Question 2

What are the three different plate boundaries?

Answer 2

– Constructive plate boundary
– destructive plate Boundry
– conservative plate boundary

Question 3

How did the plates move in a constructive plate boundary

Answer 3

Two tectonic plates are moving apart from one another . The gap in the crust causes magma to rise and cool . Earthquakes and volcanoes are found here

Question 4

How do the plates in a destructive plate boundary move ?

Answer 4

When two plates move to yards rand other one sinks ( is subducted ) below the other one Volcanoes and earthquakes are found here

Question 5

What happens during a conservative plate ?

Answer 5

When two plates are moving side by side in different directions or the same direction but at different speeds. Earthquakes are found here

Question 6

How do plates move ?

Answer 6

1. ) the mantle is a semi molten layer of rock on which the tectonic plates are floating
2. ) heat from the core causes convection currents in the mantle , where the heated rock rises towards the crust
3. ) this causes the tectonic plates(crust) to love constantly either towards or away from one another
