Its all your fault!
I have boundaries!
Its a small world after all...

Name the foru layers
Inner core Outer core Mantle Crust
100
What is one theory of how plates move?
Convection Currents
100
What type of scientist studies the Earth?
Geologist
200
At what boundary does shearing occur?
Transform
200
What happens at a Transform boundary?
Plates slide past each other.
200
Which layer is "putty-like"?
Mantle
200
What are the two types of movements?
Ridge-Push and Slab-Pull
200
What happens to seismic waves as they travel through the earth?
They change speed and direction depending on the density and material they travel through
300
What happens at subduction zones?
Volcanoes One plate goes under another
300
What can form at Divergent boundaries?
Rift valleys
300
Which layer is under lots of pressure?
Inner core
300
Which mountains are formed due to compression forces (forces pushing in from opposite directions)?
Folded mountains
300
What is the plate movement theory?
Convection in the mantle circulates material and moves plates
400
Where are plate boundaries found?
At the edge of plates
400
What is subduction? At what boundary does it occur?
One plate slides under another At convergent boundaries
400
Where is the lithosphere?
Crust and upper mantle
400
Name two countries on the Indo-Australian Plate.
Australia and India
400
What is Ridge-push?
Plates slide down the slope at mid-ocean ridges
500
What moves the plates?
Convection currents
500
List each plate boundary and tell me what is created (mountains, earthquakes, valley, volcanoes)
Convergent: mountains, volcanoes, earthquakes Transform: earthquakes Divergent: valley
500
Why is the inner core so dense and under so much pressure?
Due to the rest of the Earth layers pressing in on it
500
What is an example of a volcanic mountain?
Mt. Saint Helens Hawaii
500
What is Slab-pull?
Plates move away from mid-ocean ridges and become denser
