Earth’s inner core is a _____________ 

What is a dense ball of solid metal?

100
Which layer is the coolest?
What is the crust?
100
Why do we differentiate between the outer and inner core?
Because the outer is liquid and the inner is solid.
100
The part of the mantle called the __________ is made of soft rock that bends like plastic.
What is the asthenosphere?
100

What happens when a P-wave enters a new material/layer?

What is the wave bends (refracts) because it either slows down or speeds up?

200

This layer of the Earth is solid rock composed of Oxygen, Silicon, and Aluminum.

What is the crust?

200

Which layer is the hottest?

What is the inner core?

200
Why is the inner core solid?
What is extreme pressure in the outer core?
200

What are the convection currents within the mantle responsible for?

What is moving the tectonic plates?

200

S-waves and P-waves are detected from 5,200 km to 6,300 km deep. What medium would this layer be?

What is a solid?

300

Earth’s mantle is composed mainly of a.molten metal. b.a layer of molten rock. c.of solid metal. d.granite and basalt

What is a layer of molten, semi-solid rock?

300
Which layer is warmer, The lithosphere or the asthenosphere?
What is the asthenosphere?
300
The outer core is composed of ______________.
What is liquid nickel and iron?
300

Why does the hot mantle rise?

What is the density decreases because the particles become farther apart, causing it to rise?

300

Where do scientists believe the Earth's core generated its heat? Choose the one that does NOT apply.   

a. Energy from collisions   

b. The sun baking it  

c. Breakdown of unstable elements  

d. Gravity pulling dense objects further into Earth

What is b. the sun baking it?

400
Earth’s solid inner core is surrounded by the hot, molten metal of which layer?
What is outer core?
400
Which layer is warmer, The outer core or the inner core?
What is the inner core?
400

The inner core is composed of _________________.

What is solid iron and nickel?

400

The mantle is heated and rises and then cools and sinks. What is this process called?

What is convection currents?

400

How did the Earth's layers form?

What is: the higher density materials got pushed lower into the Earth and the less-dense materials "floated" to the top of the Earth. Meaning crust is the least dense and the solid iron core is the most dense.

500

What caused the Earth form into layers of crust, mantle, outer core, and inner core?

What is differing densities or differentiation of substances?

500
What happens to temperatures as you go deeper into the Earth?
What is they increase or get higher?
500

Scientists think that the _____________ moves to produce Earth’s magnetic field.

What is the outer core?

500

This layer makes up the lower part of the mantle and the top part of the outer core.

What is the mesosphere?

500

Name the two types of seismic waves AND what each of them can travel through.

S-waves (secondary waves) - these can travel through solids.

P-waves (primary waves) - these can travel through solids, liquids, and gasses
