Question 1

Travel like an "s" and arrive second

Accepted Answer

S waves

Question 2

One way we know about the earth's internal layers is by analyzing shadow zones caused by

Accepted Answer

seismic waves, p waves, s waves

Question 3

Travel fastest and are compression waves

Accepted Answer

P waves

Question 4

Bend when go through a different layer with different densities or materials

Accepted Answer

both

Question 5

Where did the heat come from that is still inside the planet today?

Accepted Answer

Collisions of smaller rocks that combined to make our planet, Radioactive Decay, Movement of particles in our planet

Question 6

The physical layers - the solid but movable layer where the convection currents are found

Accepted Answer

asthenosphere

Question 7

What forms when two oceanic plates pull apart?

Accepted Answer

Midocean Ridges (an under ocean mountain range)

Question 8

The direction of our magnetic field was recorded in

Accepted Answer

the hardened lava of new sea floor

Question 9

What forms when two continental plates pull apart?

Accepted Answer

Rift Valley

Question 10

How do we know the outer core is liquid?

Accepted Answer

The S waves won't go through it

Question 11

Travel through solids only

Accepted Answer

S waves

Question 12

S and P waves travel faster when

Accepted Answer

they go through more dense materials

Question 13

What is the name of the type of boundary when two plates pull apart?

Accepted Answer

Divergent

Question 14

Why do the plates (made out of lithosphere) move?

Accepted Answer

Convection currents in the mantle

Question 15

What is the name of the Plate Tectonic Boundary in which the plates push together?

Accepted Answer

Convergent

Question 16

The highly pressurized super hot solid iron layer

Accepted Answer

inner core

Question 17

If an oceanic plate pushes into a continental plate, what will happen?

Accepted Answer

The oceanic plate will push below the continental plate

Question 18

What is the name of the outer compositional layer made out of less dense materials?

Accepted Answer

crust

Question 19

When the oceanic plate dives below the continental plate, what forms?

Accepted Answer

trenches, volcanic mountains/islands, and deep earthquakes

Question 20

If a seismic wave speeds up, you know it is now going through a layer that is...

Accepted Answer

more dense

Question 21

The physical layers - Outside solid breakable layer

Accepted Answer

lithosphere

Question 22

The process that causes layers to form in our planet as more dense particles sunk to the center

Accepted Answer

Differentiation

Question 23

What do we see at transform boundaries?

Accepted Answer

off set breaks with shallow earthquakes

Question 24

What is the boundary type called when two plates slide past each other?

Accepted Answer

transform

Question 25

Our magnetic field is important because

Accepted Answer

without it we would have no atmosphere, it protects us from the solar wind

Question 26

What will a rift valley (divergent) eventually become?

Accepted Answer

ocean

Question 27

Where the magnetic field of the earth originates

Accepted Answer

core

Question 28

As we go deeper into the center of the earth...

Accepted Answer

the temp goes up and the pressure goes up.

Question 29

When a continental plate pushes into a continental plate, what happens?

Accepted Answer

The plate buckles forming mountains

Question 30

The liquid iron super hot layer

Accepted Answer

outer core
