100
This is the surface layer of the Earth
What is the crust?
100
this is the thickest layer of the Earth
What is the mantle?
100
This is the layer of the Earth that is at the center of the Earth.
What is the core or more specifically the inner core
100
A direct way that scientists can study the Earth's interior and make inferences about whats really going on down there.
What is using rock samples, either by digging or rocks being blasted up by Earth's forces.
200
The crust is like this part of a chicken egg.
What is the shell
200
The uppermost part of the Mantle and the crust together form a rigid layer called this.
What is the lithosphere
200
This part of the core is a dense ball of solid metal
What is the inner core
200
An indirect way that scientists use to provide evidence for the Earth's layers.
What are seismic waves?
300
The crust beneath landforms is called this
What is continental crust
300
This refers to the "softer" part of the mantle and is found below the lithosphere
What is the Asthenosphere?
300
The movements in the outer core are suspected to create this
What is Earth's Magnetic Field
300
If you go swimming and swim too deep your ears may begin to hurt or "pop" because of this
What is increased pressure
400
The rock that composes most of oceanic crust
What is basalt
400
The lower mantle has this physical state (solid,liquid, or gas)
What is solid
400
This part of the core is liquid
What is outer core
400
As you get closer to the center of the Earth this and pressure increase.
What is temperature
500
The more dense crust (hint: oceanic or continental)
What is Oceanic
500
this is the approximate thickness of the mantle in Kilometers
What is 3000 km.
500
The Earth's core is made up mostly of these two metals.
What is iron and nickel
500
Even though the inner core is very hot it is still solid because of this
What is incredibly high pressure pushing the molecules together.
