The following diagram represents a mid-ocean ridge. Based on the diagram, which letter indicates where the new plate material is forming?
C: At the boundary where the two plates are pulling apart.

Below is a picture of sea-floor spreading. How are the ocean crusts moving? 
Diverging

The symbols found on the map below indicate where fossils have been found in the same layer of sediment. Each unique symbol represents fossil locations of a particular species. What do the locations of the fossils suggest? 
The continents were once connected to each other.
100
Which of these is NOT evidence of continental drift?
Continents fit like puzzle pieces
Fossil evidence
Hurricane damage
Climate data showing glacier evidence
Hurricane Damage
200
What is Pangaea?
A super continent
200
What's causing the continents to move?
Convection currents in Earth's mantle.
200
When an oceanic crust meets a continental crust, what occurs?
The oceanic crust moves under (subducts under) the continental crust resulting in volcanoes.
200
The theory of continental drift was first presented in 1912. Scientists once thought that the continents had formed in their current locations. Besides the fossils mentioned above, what factors MOST LIKELY caused scientists to change their opinions?
Africa, North America, and South America fit together like puzzle pieces
200
When two continental plates converge what crustal feature is expected to form?
Mountains
300
What two specific continents fit together most noticeably?
South America and Africa
300

this?
Transform Boundary

The large pieces of crust that move due to convection currents in the mantle are called _________.
Tectonic Plates
300
True or False: Oceanic crust is older than continental crust?

The San Andreas Fault in California is known as an active earthquake area. What type of boundary is it?
Transform Boundary
400
Who came up with the Continental Drift Theory?
Alfred Wegener
400
What kind of plate boundary is this modeling? 
Convergent Boundary

The diagram below shows the locations of some of the major plates that make up the Earth's lithosphere. Each plate is represented by a different color. The black lines are plate boundaries. Red arrows show which way the plates are moving. Based on the diagram, what is true about Earth's crust? 
Earth's crust is divided into plates that move relative to each other.
500
Which layer of the Earth do tectonic plates float on?
Mantle
500
What geologic event occurs at a transform boundary?
Earthquakes
500
Process where one tectonic plate bends & slides beneath another plate at a convergent boundary
subduction
500
Where is new oceanic crust formed?
in the mid-ocean ridge

The diagram below shows the locations of some of the major plates that make up the Earth's lithosphere. Each plate is represented by a different color. The black lines are plate boundaries. Red arrows show which way the plates are moving. Which arrows show that a mid-ocean ridge is likely to be found at that boundary? 
Boundary C-divergent boundary

Scientists have found rock formations dating to the late Precambrian Times in South America. These ancient rocks can be found from the eastern edge of South America's continental shelf, which extends just off the coast of Brazil, to the interior of the continent. This general location is indicated by a green circle on the map below. Scientists have also found rock formations made out of the same type of rock and from the very same eon at another location. Where did they find those rocks? 
Location C

Find the Nazca and the South American Plate. This is an example of two plates converging. The denser oceanic plate (Nazca) moves under the continental plate (South American Plate). What features are likely found here? 
volcano
600

mountain range

Ocean plates are __________ than continental plates.
more dense
(younger and thinner possible answers also)

What two scientific theories combine to make up what we know as Plate Tectonics?
Continental Drift and Sea Floor Spreading
