This is the supercontinent that existed millions of years ago.
What is Panega?
100
A collision between two pieces of continental crust at a converging boundary will produce this.
What is a mountain range?
100
The geological theory that states that pieces of Earth's lithosphere are in slow, constant motion is called this.
What is plate tectonics?
100
The lithosphere is broken up into sections called this.
What is plates?
100
At this type of boundary two plates come together.
What is convergent?
200
According to this hypothesis the continents were once joined in a single landmass.
What is continental drift?
200
This is the location where molten material erupts from the mantle in the process of seafloor spreading.
What is mid-ocean ridge?
200
Along this type of boundary, two plates slip past one another.
What is transform boundary?
200
This process will continually add crust to the ocean floor.
What is seafloor spreading?
200
This is the person that came up with the hypothesis continental drift.
Who is Alfred Wegner?
300
Alfred Wegner provided these three pieces of evidence to support his theory.
What is landforms, fossils, and climate?
300
Old oceanic crust is more dense then new oceanic crust because of this.
What is it is cooler?
300
This is what a fossil is.
What is any trace of an ancient organism that is found in a rock?
300
Subduction occurs where the oceanic crust bends down toward the mantle in this location.
What is deep ocean trench?
300
This is the part of the Earth that is broken up into plates.
What is the lithosphere?
400
These are two examples of continents that have drifted apart over time.
What is Africa and S. America; Europe and N. America; Australia and Antarctica?
400
This is the technology that scientists used to study the map the mid-ocean ridges.
What is sonar?
400
Most geologists think that movement of plates are caused by this.
What is convection currents?
400
This is the location where the youngest oceanic crust can be found.
What is mid ocean ridge?
400
These are three pieces of evidence that seafloor spreading occurs.
What is evidence from ocean material, magnetic stripes, and drilling samples?
500
This is evidence from fossils and landforms that support continental drift.
What is rock from mountain ranges in Africa match up with rock from mountain ranges in S. America; A type of fossil plant has been found on both continents?
500
If subduction occurs slower, than oceanic crust can be created, the ocean will do this.
What is expand?
500
This is what breaks in the Earth where rocks slip past one another is called.
What is a fault?
500
When continental plates pull apart at a divergent boundary this is formed.
