Which direction of plate movement will MOST likely result in the formation of an ocean basin?
What is a divergent boundary <-- -->
100
The name of Plate A
What is the Eurasian Plate
100
The "puzzle pieces" that the Earth's crust and upper mantle are broken into
What are tectonic plates
100
When the edges of tectonic plates shift and energy is released, these occur
What are earhquakes
100
Name for the short comings or defects of models (Example: The styrofoam Earth model could not use the same states of matter as the real Earth.)
What is a limitation.
200
Place where most active volcanoes occur
What is along plate boundaries
200
The name of Plate B
What is the North American Plate
200
The man who noticed that the continents seem to fit together. He came up with the theory of moving continents (crazy little man).
Who is Alfred Wegener
200
When divergent boundaries pull apart and new crust is formed under the ocean, these are formed
What is rift valleys or mid-ocean ridges
200
Geologists believe that our continents will look like 400 million in the future
What is a supercontinent
300
Type of boundary that results in folded mountains
What is a convergent boundary --> <--

The name of Plate D
What is the South American Plate
300
The layer of the Earth that the tectonic plates 'float' on
What is the asthenosphere
300
Pushing two folded towels together would best model the formation of _______________ formed at _____________ boundaries.
What is mountains at convergent boundaries
300
Where the newest crust on Earth is found
What is at divergent boundaries
400
Type of boundary that causes fault lines and earthquakes
What is a transform boundary ---> <---

The name of Plate E
What is the Indo-Australian Plate
400
Describe the Theory of Plate Tectonics
The Earth's crust and upper mantle are divided into plates that are constantly moving atop the asthenosphere.
400
Thin, dense plates containing basalt
What are oceanic plates
400
Divergent boundaries create new crust. Explain why the surface of the Earth does not get larger.
Crust is recycled and pushed back into the asthenosphere at subduction zones of convergent boundaries. Crust is also pushed up and folded at convergent boundaries.
500
The process at a convergent boundary where a denser ocean plate goes under a less dense continental plate
What is subduction
500
The name of Plate F
What is the African Plate
500
The name of the 'supercontinent' that geologists believe existed over 300 million years ago
What is Pangaea
500
Thick, less dense plates containing granite
What are continental plates

At the ridge crest in the sea floor, hot magma rises because it is less dense than the surrounding magma. When it reaches the surface it cools and hardens becoming the sea floor. At plate boundaries, the cold and more dense rock sinks and melts, becoming magma once again. What is this process of heat transfer called?
What are convection currents.
