What is the Ring of Fire?
A famous earhquake zone in the Atlantic Ocean
A region where many meteor impacts occur
A belt of volcanic activity in the Arctic
A series of volcanoes in the Pacific Ocean
Which of the following is TRUE about the theory of continental drift?
The continents have always been in their current positions.
There was once a supercontinent called Pangaea.
Continental drift is unrelated to plate tectonics.
The movement of continents is caused by ocean currents.
Who developed the theory of continental drift?
Marie Curie
Alfred Einstein
Elvis Presley
Alfred Wegener
Continental plates are less dense than oceanic plates.
False
True
Where are most volcanic eruptions like to occur?
At transform boundaries
In the middle of continents
In places where there are no plate movements
At convergent and divergent plate boundaries
What are the two kinds of tectonic plates?
Oceanic and Continental
What kind of plate boundary is this?
Transform
Convergent
Convection
Divergent
Earthquakes are most commonly associated with which type of plate boundary?
All types of plate boundaries cause earthquakes
Convergent
Divergent
Transform
What happens at a transform boundary?
Plates move downward into the mantle.
Plates move away from each other and form new crust.
Plates slide past each other horizontally; earthquakes
Plates move towards each other and form mountains.
The Himalayas were formed by the collision of which two tectonic plates?
North American and Eurasian
Pacific and North American
African and South American
Indian and Eurasian
Which tectonic plate is B.C. on?
Antarctic
Indo-Australian
South American
North American
Which of the following is NOT evidence supporting the theory of plate tectonics?
The matching of rock layers on different continents
The presence of deep ocean trenches only at mid-ocean ridges
The distribution of similar fossils across continents
The shape of the continents, which appear to fit together
The process of one tectonic plate sliding underneath another is known as:
Earthquake
Convection
Subduction
Seafloor spreading

What is the primary force driving the movement of tectonic plates?
Earth's magnetic field
The Earth's rotation
Convection currents in the mantle
Wind currents
What kind of plate boundary is the Mariana Trench an example of?

What is formed when two tectonic plates collide at a convergent boundary?
Mountain ranges or deep ocean trenches
Volcanoes
Earthquakes ONLY
Ocean ridges
What kind of plate boundary is this?

Which of the following best describes the Earth's lithosphere?
The inner core of the Earth
The rigid outer layer, which is broken into tectonic plates
A region where oceanic plates meet continental plates
The layer of molten rock beneath the crust
What is the main theory behind plate tectonics?
The Earth’s core is made of solid iron only.
Earth's continents are fixed in place.
The Earth’s crust is completely solid and does not change.
Earth's outer layer is divided into large, moving pieces.
What is seafloor spreading?
The sinking of oceanic plates at subduction zones
The formation of new volcanoes in the ocean
The movement of continents across the ocean floor
When new oceanic crust is created at mid-ocean ridges
