Vocabulary
100
The name of the giant super continent.
What is Pangaea?
100
This occurs at convergent boundaries.
What is come together?
100
This occurs at divergent boundaries.
What is separate?
100
This occurs at transform boundaries.
What is slide past one another?
100
The plates are part of this layer of Earth.
What is the lithosphere?
200
The continents use to fit together like this.
What is a puzzle piece?
200
This is the number of different types of convergent boundaries.
What is three?
200
This is created when two plates divide.
What is new crust?
200
True or False. Crust is neither created nor destroyed at transform boundaries.
What is true?
200
Convection currents occur in this layer of Earth.
What is the asthenosphere?
300
The Father of Continental Drift Theory.
Who is Alfred Wegener?
300
Island Arcs occur at this type of convergent boundary.
What is ocean-ocean convergent boundary?
300
This land feature forms when plates separate and magma is forced upward.
What is volcanoes?
300
This fault is located in California.
What is San Andreas Fault?
300
This occurs when a more dense plate, goes beneath a less dense plate.
What is subduction?
400
True or false. Other scientist agreed with this theory.
What is false?
400
The Himalayas were formed at this type of convergent boundary.
What is continent-continent convergent boundary?
400
This is where the longest mountain range is found. (hint: it is not on land)
What is the Mid-Atlantic Ridge?
400
This activity occurs alond fault lines.
What is an earthquake?
400
The rising and falling of magma causes these.
What are convection currents?
500
This evidence supports the continental drift theory. (There are three)
What is fossil evidence, continent shape, mountain ranges?
500
The more dense plate slides beneath the less dense plate. This occurs at what type of plate boundary?
What is ocean-continent convergent boundary?
500
The convection currents do this at divergent boundaries.
What is rise when heated, separate, and fall when cooled?
500
The reason earthquakes occur.
What is energy is stored, and suddenly released?
500
When two plates divide, this can be formed.
What is a rift valley?
