potpourri
100
It is the outer most layer and also the thinnest
What is the crust
100
This is the name of the super continent is Alfred Wegener's theory on plate tectonics
What is Pangea
100
The location in the crust where an earthquake originates
What is the focus
100
The opening in a volcano where magma reaches the surface
What is the vent
100
The study of earthquakes
What is seismology
200
It is the largest layer of the Earth
What is the mantle
200
These plate boundaries collide together to form mountains and volcanoes
What are convergent plate boundaries
200
These waves cause the most damage.
What are surface waves
200
The areas where volcanoes occur (there are 3)
What are convergent plate boundaries, divergent plate boundaries and hot spots
200
The scale that measures the magnitude of an earthquake.
What is the Richter scale
300
The inner core is this state of matter
What is a solid
300
These plate boundaries move away from each other to form rift valleys and oceanic ridges
What are divergent plate boundaries
300
These are also known as primary waves
What are longitudinal waves
300
These types of volcanoes have mild eruptions
What are shield volcanoes
300
The theory that explains the movements of continental plates
What is continental drift or plate tectonics
400
This layer is composed of the crust and the upper portion of the mantle
What is the lithosphere
400
These plate boundaries slide past each other and create fault lines and earthquakes
What are transform plate boundaries
400
The area on the Earth's surface that an earthquake causes the most damage.
What is the epicenter
400
These volcanoes have violent eruptions due to their trapped gas.
What are composite volcanoes
400
These cause the Earth's interior to increase temperature with depth
What is radioactive isotopes
500
This layer is composed of the liquid portion of the mantle
What is the asthenosphere
500
The zone where continental crust dives beneath oceanic crust
What is a subduction zone
500
These are also called secondary waves.
What are transverse waves
500
Most cinder cone volcanoes occur in these
What are hotspots
500
This is the evidence that Alfred Wegener used to help support his theory (there are 3)
What is the continents fitting together like a puzzle, similar fossils on opposite continents, and the magnetic polarity of rocks at ocean ridges.
