Earths Layers And Plate Boundaries

Question 1

Lithosphere

Answer 1

Solid outer section of earth that includes the crust and the rigid upper part of the mantle

Question 2

Asthenosphere

Answer 2

Solid part of the upper mantle, weaker, less rigid ,plastic like ,crust move over it

Question 3

Volcanic island ark

Answer 3

Occurs when two oceanic plates collide in the older crust goes beneath the younger one

Question 4

Is oceanic crust, more dense, or less dense than continental?

Answer 4

More

Question 5

Answer 6

Younger

Question 7

Answer 7

Mantle

Question 8

What layer contains solicit rocks?

Answer 8

Mantle

Question 9

What layer creates earths magnetic field

Answer 9

Outer core

Question 10

Which layer contains tectonic plates

Answer 10

Crust

Question 11

What is the tectonic plate theory?

Answer 11

The theory that earths outer crust (lithosphere)
Is divided into several plates that glide over the plastic like in less ridged athenosphere (upper mantle)

Question 12

Where is the Ring of fire located?

Answer 12

Around the Pacific Ocean

Question 13

What happens in the ring of fire and what causes it

Answer 13

Frequent earthquakes and volcanoes caused by plate boundaries, converging, diverging, and transforming

Question 14

What does a divergent plate boundary create

Answer 14

Rift valleys for continental and Sea for spreading for oceanic

Question 15

What does a transform boundary create?

Answer 15

Earthquakes/fault lines EX: the San Andreas Fault

Question 16

What is a convergent plate boundary collision create

Answer 16

Mountains

Question 17

What does a convergent plate boundary subduction create for two oceanic crusts

Answer 17

Volcanic arc of islands

Question 18

What does a convergent plate boundary subduction create for ocean and continent?

Answer 18

Volcanoes
