The Core-Inner and Outer
The innermost region of the Earth is known as this.

Alfred Wegener.
This scientist theorized that all of Earth's continents were all once connected.
100
Divergent plate boundaries
Mid-Ocean Ridges occur in this area.
100
Strato/Composite Sheild/Flood Cindercone
These are the main types of volcanoes.
100
Richter
Earthquakes' magnitudes are measured on this scale.
200
Temperature; density
What increases when going deeper under the Earth's surface?
200
Fossils Mountain Ranges Rock Deposits Climate
These pieces of evidence support Wegener's theory.
200
Density of plates
The process of subduction occurs because of this factor.
200
Pyroclasts
Cindercone volcanoes release large amounts of this material.
200
Comparing timing of shortwaves from different distances and locations.
Epicenter of earthquakes can be found be doing this.
300
Oceanic-Denser Continental-Thicker
The difference(s) between Oceanic and Continental Crust
300
Constantly occuring
The process of continental drift is this.
300
Volcanic activity
Subduction can cause this.
300
Rhyolitic magma in these volcanoes builds up before being it is released.
Shield volcanoes are the most explosive because of this.
300
Transform
The San Andreas Fault Line is on this plate boundary
400
The Outer Core
Excluding the Asthenosphere, this part of the Geosphere is liquid.
400
Lack of any explanation
The theory of continental drift not accepted when first proposed because of this.
400
Convection form the mantle and core form new crust, pushing old crust away
This causes plates to move.
400
Mineral composition
Melting point of rocks are determined by this.
400
All of them
Earthquakes appear on these plate boundaries.

{Crust Uppermost Mantle}-Lithosphere Asthenosphere Upper Mantle Lower Mantle Outer Core Inner Core
List all the regions of the geosphere in order of shallowest to deepest in location.
500
Pangea
The super continent in the theory was called this.
500
Subduction Slab pull
Gravity makes this possible.
500
Basalt
Oceanic crust is mainly made of this igneous rock.
500
Primary Secondary I or Surface Waves
The types of waves from earthquakes are these.
