100
The 4 major layers of Earth.
What is crust, mantle, outer core and inner core.
100
The theorist who proposed the theory of Continental Drift.
What is Alfred Wegener
100
The fastest and first wave to arrive at the location, passes through solids, liquids and gases.
What is P-Wave.
100
Type of magma that will produce violent eruptions.
What is high silica magma.
100
The breakdown of rock into smaller and smaller pieces?
What is weathering.
200
The thickest layer.
What is the mantle.
200
The idea that the continents where joined as a single land mass at one point in time.
What is Pangaea.
200
The second and slowest wave to arrive at a location, passes only through solids.
What is S-Wave
200
The type of lava to create ropey formations as it quickly hardens.
What is Pahoehoe lava.
200
Causes weathering by abrasion.
What is wind, water and gravity.
300
Contains nickel and iron.
What is the inner core.
300
The recycling of the Earth's crust through rising and sinking motions.
What is convection currents.
300
An instrument located near the surface to trace seismic waves.
What is seismograph.
300
The theory that explains the causes and formations of both earthquakes and volcanoes.
What is Theory of Plate Tectonics.
300
A chemical reaction in which an element such as iron, combines with oxygen to form an oxide.
What is oxidation.
400
The layer that is in constant motion.
What is the mantle.
400
This is found when a denser crust sinks below a less dense crust.
What is Subduction Zones
400
These three boundaries are the causes of convection currents located in the mantle.
What is Divergent, Convergent and Transform Boundaries
400
The three ways Volcanoes are formed.
What are divergent, convergent and hot spots.
400
A process by which softer less resistant rocks wear away, leaving harder, more weather resistant rocks behind.
What is differential weathering.
500
The layer where the plates are in movement.
What is the lithosphere.
500
In one of the movies watched in class, this location was known for its ring of volcanoes.
What is The Ring of Fire.
500
The point on the Earths' surface directly above an earthquakes starting point
What is the epicenter.
500
The three types of Volcanoes.
What is Shield, Cinder, Stratovolcano
500
The process by which wind and water transport soil and sediment from one location to the other.
What is Erosion?
