Answer 6

Basalt

Question 7

How thick is the oceanic crust?

Answer 7

0-15km

Question 8

No as the continental crust is 30-75 km

Question 9

What is the lithosphere?

Answer 9

A rigid outer part of the earth, consisting of the crust and the upper mantle

Question 10

What is the asthenosphere?

Answer 10

The lower layer of the earth’s mantle, below the lithosphere, with relatively low resistance to plastic flow and convection occurs

Question 11

Answer 11

Continental crust

Question 12

Answer 12

Oceanic crust

Question 13

How thick is the oceanic crust’s crystals that form?

Answer 13

6-10km thick

Question 14

How thick are the continental crust’s crystals that form?

Answer 14

30-50km

Question 15

Is continental or oceanic crust more denser?

Answer 15

Continental crust

Question 16

What is the tectonic plate theory?

Answer 16

The theory that the earth is made up of moving plates

Question 17

What is slab pull?

Answer 17

As the more dense plate sinks in the asthenosphere, it continues to pull the rest of the plate with it
