The center of the earth is broken up into these two layers.
What are the Inner and Outer Layers of the Earth?
100
This type of heat transfer is seen when the sun heats up the earth.
What is radiation?
100
This devices used sound waves to detect differences on the ocean floor.
What is sonar?
100
These pieces of the Earth's crust 'float' around on the softer layers of the Earth.
What are tectonic plates?
100
This is the largest animal that has ever existed on the Earth.
What is the Blue Whale?
200
This layer is a soft texture, being not quite solid but not liquid.
What is the mantle?
200
This type of heat transfer is created by the heat of the core and causes the sea-floor to spread.
What is convection?
200
The sea floor starts to spread out from this line on the sea-floor.
What is the mid-ocean ridge? (Mid-Atlantic Ridge Also acceptable)
200
This type of boundary occurs when two plates come together.
What is a 'convergent boundary'?
200
This animal is named comes from "Orcinus" which is greek for Kingdom of the Dead.
What is Killer Whale (Orca)?
300
This section of the earth includes the crust and the solid top of the mantle.
What is the lithosphere?
300
This scientist used fossils, land features, and evidence of climate change to support his theory of drifting continents.
Who is Alfred Wegener?
300
This is the scientist who used molten material, magnetic strips, and drilling samples to support the theory of sea-floor spreading.
Who is Harry Hess?
300
These lines are the cracks in between two plates of crust.
What are faults?
300
This arctic carnivore can swim for over 100 miles without resting.
What is a polar bear?
400
These waves are created by Earthquakes and are used to understand what the inside of the earth is like.
What are seismic waves?
400
Scientists believe the modern day continents were all once part of this is the super continent.
What is Pangea?
400
In this process old sea floor is "swallowed" underneath the continental crust.
What is 'subduction'?
400
A divergent boundary on land sometimes creates this land formation.
What is a rift valley?
400
These animals can hear vibrations through their feet on the ground from over 20 miles away.
What are elephants?
500
This is the first place that the impact of an earthquake hits on the surface of the crust.
What is the "epicenter"?
