100
The biggest layer and the smallest layer of the earth.
What is the mantle (biggest) and the crust smallest?
100
What is the idea of continental drift?
Continents fit together to form one big continent the "Pangaea." Continents slowly moved apart.
100
What is the fastest earthquake wave?
Primary wave.
100
What can happen during a volcanic eruption?

Torrents of water, mud, and debris fly around. Mixture of dirt, water, and rocks fly around. Deadly gases can spread.

100
Give evidence of continental drift. 
Evidence: Fossils have matched in South America and Africa. Similar rock beds in South America and Africa.

Coal beds in Antarctica and glacial rocks in Africa.

200
What core is a liquid core and what core is a solid core?
Outer core (liquid) Inner core (solid).
200
What is seafloor spreading? 
The process of forming new ocean crust created by eruptions of lava at the spreading center.
200
The slowest earthquake wave.
Surface wave or L-wave.
200
What volcano forms at hot spots?
Shield Volcanoes


200
Describe how the flood might have sped up how fast plates move.
Since plates move slowly it would take a long time to move that far apart so scientists believe that plates might have moved faster during the flood.
300

Why does the oceanic crust sink below the continental crust? 

The density of oceanic crust (3.3 g/cm3)is higher than the density of continental crust (2.7 g/cm3).

300
Describe what the theory of plate tectonics is. 
The lithosphere is broken into seven major tectonic plates. The plates move slowly over the earth's surface. Plates move around melted sections of the earth.
300
What wave travels perpendicular to the direction of motion.
Secondary wave or S-wave.
300
What volcano produces highly explosive eruptions?
Composite volcanoes
300
What are the three earthquake faults?
Hangingwall fault

Footwall fault                                                           Strike-slip fault

400
Describe Lithosphere and Asthenosphere.
Lithosphere: A rigid like rock, together like crust.

Asthenosphere: A soft plastic, together like the mantle.

400
Plates are caused by what?
Convection Currents.
400
What happens during an earthquake.
Things crumble, tsunamis can start and things get sent from place to place, a building can fall.
400
What volcano erupts volcanic ash and cinder?
Cinder volcanoes
400
Name all four layers of the earth from outside to inside.
Crust, Mantle, Outer core, and Inner core.
500
Why does uniformitarianism require long ages of earth's history? 
Natural processes have always been at the same rate. So, it would give more time to process things if earth was around for millions of years. 
500
Where plates move apart. Where plates come together. Where plates move horizontally.
1. Divergent

2. Convergent                                                           3. Transform

500
What can happen during an 8.0 earthquake?
Total destruction objects thrown in the air, river courses alerted.
500
Name all three earthquake waves and all three volcano types.
Primary wave (p-wave), Secondary wave (s-wave), and Surface wave (l-wave). Cinder volcano, Composite volcano, and Shield volcano.
500
Name five parts of a volcano.
Crater, vent, lava flow, throat, side vent, parasitic cone, flank, base, layers of lava and ash emitted by the volcano, branch pipe, magma chamber, and conduit pipe.
