What is the mechanism for continental movement?
What is heat transfer by convection currents.

Iceland is located in the middle of the mid-oceanic ridge. What kind of disaster/s disrupt the ecosystem here?
What is a volcanic eruption? Earthquakes too.
300
What is the evidence for seafloor spreading?
What is drilling samples, magnetic stripes and rock type (molten material).

What is the name of the sphere that includes water on Earth. Name 3 sources of water on Earth.
What is the Hydrosphere. 3 sources: oceans, rain, rivers, lakes, glacial ice, groundwater etc.

In 1975 Alvin an deep sea diving capsule found a new "underwater ecosystem" along the mid-oceanic ridges. Tube worms and large crabs are found here. This area is called a:
What are hydrothermal vent

When two plates move in opposite directions from one another they generate crustal stress and release it. This is called a/an
What is an earthquake

In Utah we live on/near the north/south trending Wasatch Fault. We will have earthquakes in the future. What are some of the ways we can prepare for earthquakes.
What is a disaster preparedness kit. Escape route & contact plan. Know what to do when an earthquake hits.
400
The German scientist Alfred Wegener noted 4 pieces of evidence for his continental drift hypothesis. What are these pieces of evidence?
What is rock type, puzzle piece fit, landforms, climate & fossils
400
What is the asthenosphere? What is it part of?
The asthenosphere is the semi-liquid zone in the upper mantle. The lithosphere move on top of it.
500
What are the names of two smaller plates we learned in class
Juan de Fuca, Cocos, Scotia or Somalian
500
Name the three processes (directions) of movement along plate boundaries.
What is convergent, divergent and transform. Draw the directional arrows
500
In 2011 of the coast of Japan plate movement occurred. What was generated? How did this form?
What is a tsunami. It formed by water displacement which built up wave surges towards land.
500
What is magnetic stripe evidence?
Magnetic stripe data is found in ocean crust. Scientists date the rock and note the magnetic dipole orientations N and S. They find stripes or a pattern occurs when poles reverse over millions of years.
