What is the epicenter of an earthquake?
Directly above the earthquake focus on the surface
100
What is a plate boundary?
When two or more tectonic plates come together cause build up of friction
100
True or False; The earth gets hotter as you get closer to the core?
True
100
True or False; Is lava and magma the same thing?
True, Magma is the name when it is inside the earth, Lava is when it reaches earths surface. Both are MOLTEN rock
200
What can be closely associated with earthquakes if you live by ocean?
Tsunamis
200
Name all 3 types of Plate Boundaries
Convergent Boundary Divergent Boundary Transform Boundary

What is the approximate temperature at the center of the earth?
6000 degrees celsius

TEAM CHALLENGE Name the plate boundary that is close to us and the names of the 2 tectonic plates that are involved?
Convergent Boundary North American Plate Juan De Fuca Plate
300
What is a subduction zone?
Convergent Boundary when oceanic crust goes beneath a continental crust
300
Why are we not able to see the earth's plates moving?
They are so big and moving so slow we do not realize they are moving still
300
What is a hot spot
Magma rising to surface NOT on a plate boundary
400
How are Tsunamis produced?
An earthquake occurs under the ocean causing large amounts of water to move
400
TEAM CHALLENGE Using the foam, demonstrate all three plate boundaries
Convergent, Divergent, Transform
400
How fast do the tectonic plates move in a year?
2.5 cm a year
400
True or False; Volcanoes can appear at ALL plate boundaries?
False, They occur at convergent, divergent and hot spots only
500
If there was an earthquake right now, what is the first thing you should do?
STOP! DROP! and HOLD ON!
