Earth's Layers
The force that was responsible for the collision between the particles that formed Earth when Earth was just a cloud of dust surrounding the sun.
What is gravity?
The type of seismic wave that can travel through liquids and solids
What is P wave?
The theory proposed to explain continental drift and sea floor spreading
What is the theory of plate tectonics?
Mountains commonly form at this plate boundary
What is convergent?
The three types of volcanic mountains
What is cinder cone, shield, and composite?
The source of heat in Earth's interior
What is radioactive decay?
The technology/type of wave used to measure Earth's layers
What is seismic waves/seismic technology?
The three types of plate boundaries and their descriptions
What is convergent=collide, divergent=divide, and transform=slide?
The two types of rock folds and their descriptions
What is syncline= "U" shape and anticline= upside down "U" shape
A crack in the ground where lava flows out. This can form lava plateaus.
What is fissure?
The top-most layer of the Earth that contains the crust and upper mantle
What is Lithosphere
The name of the machine used to measure seismic activity
What is seismograph?
The difference between continental and oceanic crust
What is oceanic crust is more dense than continental/oceanic is thinner?
Tectonic forces can cause stress. This type of stress causes folding and often takes place at convergent boundaries
What is compression?
This is what forms within the mantle, below the lithosphere, and forms hot spots.
What is mantle plume/buldge?
The term for the physical layers of the earth
What is mechanical layers?
The unit used to measure continental movement over time
What is centimeters/year?
This type of fault has two fault blocks that moves past each other horizontally.
What is strike-slip?
The name of the largest volcano ever discovered
What is Olympus Mons?
The five mechanical layers of Earth in order from top to bottom (outside to inside)
What is the Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core?
The name of the geologist who proposed the theory of continental drift
Who is Alfred Wegener?
When looking at a fault plane, one fault block is "on top" and another is "below" the plane. Name these fault blocks.
What is hanging wall and footwall?
Rocks and debris from an eruption is also known as pyroclastic material. The way in which pyroclastic material is released differs from lava in this way.
What is lava "flows" out, while pyroclastic material explodes outward.
