The hypothesis that all the continents were once joined together in a singular landmass, called Pangea, and have since drifted apart.
What is Wegner's Hypothesis?
100
The top layer of the Earth's interior.
What is the crust?
100
This of boundary occurs near mountains.
What is a convergent boundary?
100
This is the process by which seismologists use 3 seismograph stations to surround and locate the epicenter of an earthquake.
What is the triangulation?
100
This occurs when groundwater in heated by a nearby body of magma or by hot rock deep underground.
What are hot springs?
200
This theory is supported by the shape of continents, mountain ranges, fracture zones, glaciers, and fossils.
What is Continental Drift?
200
This layer of the Earth's interior is roughly 3000 kilometers deep.
What is the mantle?
200
This type of boundary creates Earthquakes.
What is a transform boundary?
200
Seismologists use triangulation to find information about these characteristics of an earthquake.
What is the epicenter/magnitude?
200
This is when rising hot water and steam are trapped underground in a narrow crack, causing the water to spray above the surface.
What is a geyser?
300
Convection currents in the Earth's mantle.
What causes continental drift?
300
This is the only fully liquid layer of the Earth's interior.
What is the outer core?
300
This type of boundary is related to mid-ocean ridges, and sea-floor spreading.
What is a divergent boundary?
300
Waves that compress and expand the ground like an accordion.
What are P-waves?
300
This Hawaii island was formed about 4.9 million years ago
What is Nihau
400
This states that pieces of the lithosphere are constantly, slowly moving, driven by convection currents in the mantle.
What is the theory of plate tectonics?
400
This layer of the Earth's interior is semiliquid/solid.
What is the mantle?
400
This type of geological feature occurs at divergent boundaries.
What is a rift valley?
400
These are the slowest kind of seismic waves.
What are surface waves?
400
This island began to form about 430,000 years ago.
What is Hawaii (The Big Island)
500
The process by which the sea floor spreads when new crust is added along a mid-ocean ridge. This causes ocean floors to act like conveyor belts, moving continents with them.
What is sea floor spreading?
500
This is the hottest layer of the Earth is mostly made up of Iron and Nickel.
What is the outer core?
500
A plate boundary that is marked by features such as fault lines (ex: the San Andreas fault)
What is a transform boundary?
500
These are seismic waves that move the ground side by side as well as up and down.
