Earths outer layer is divided into sections called
zones
plates
continents
countries
New plates are formed at the
Convergent Plate Boundary
Divergent Plate Boundary
Transform Fault
The plates of Earth's outer layer can
move very slowly
move very fast
not move at all
move to fast to measure
This boundary allows two plates to move away from each other.
convergent boundary
fault boundary
divergent boundary
transform boundary
Fossil remains of Lystrosaurus (an extinct four-legged animal) have been discovered in India and South Africa. When they were living, all the Lystrosaurus lived together on land, and they could not swim. However, now there is an ocean between the Lystrosaurus fossils.
What could explain how these fossils got so far apart?
India and South Africa are parts of different plates. The plates slowly diverged as soft, solid rock from underneath got added to the edges of the plates over millions of years.
India and South Africa are parts of different plates. The plates floated away from each other across the ocean.
India and South Africa are parts of different plates. The plates slowly converged as new plates from underneath got added between them over millions of years.
India and South Africa are parts of different plates. The plates were sometimes pushed far apart by earthquakes, and soft, solid rock from underneath got added to the edges of the plates.
Which geological feature is commonly associated with transform boundaries?
Earthquakes
Volcanoes
Mountain ranges
Ocean trenches
Most geologists think that the movement of Earth’s plates is caused by _______ / La mayoría de los geólogos piensan que el movimiento de las placas de la Tierra es causado por _______
convection / convección.
continental drift / deriva continental.
subduction / subducción.
conduction / conducción.
Can people living on the North American and Eurasian plates feel them moving apart? Why or why not?
Dr. Raisa and her team of geologists have been studying GPS data that shows that two plates that have diverged. Which diagram shows what happened between the two plates as they moved away from each other?
Diagram A: A new plate from underneath filled in the gap that was created by the plates moving apart.
Diagram B: Sand and dirt filled in the gap that was created by the plates moving apart.
Diagram C: Ocean water filled in the gap that was created by the plates moving apart.
Diagram D: Soft, solid rock from underneath the plates rose and hardened, adding solid rock to the edges of both plates
When oceanic and continental crust converge, the oceanic plate will dive beneath the continental plate. What best explains the results of this action?
The oceanic crust is moved upward by the radiation of heat
The oceanic crust will melt as it moves deeper in the earth.
The continental crust will form a mountain range.
The two crusts will form an ocean basin
Dr. Patel and her team have been using GPS to track two plates that are moving toward each other.
Which diagram shows what is happening at the place where the plates are converging?
Diagram A: Two plates are hitting each other, and the plates are breaking into pieces, creating sand.
Diagram B: Two plates are pushing against each other, causing the edges to bend upward.
Diagram C: One plate is subducting underneath the other plate and sinking into the soft rock below.
Diagram D: One plate is going underneath the other plate and sinking into the ocean below.
Associated with transform boundaries.
Volcanoes
mountains
trenches
earthquakes
What is responsible for the motion indicated by the arrows in the image?

plate tectonics
The plates of the Earth moved
suddenly
gradually
The plates of the Earth moved / Las placas de la Tierra se movieron
suddenly / de repente
gradually / gradualmente
What is the name of the formation at A?
Mid Ocean Ridge
Sea Floor Spreading

Mid Ocean Mountain
This is a picture of a (a) boundary.
transform
convergent
divergent
Earth's plates move at a rate
5 feet per month
1 foot per week
60 miles per hour
to slow to be seen by humans but about 1 cm per year
The reason the Mesosaurus fossils were found so far away from each other is because
they once swam across the ocean
they flew to the other continent
someone carried them to the other continent
there was a divergent plate boundary which pushed the land apart.
What is the primary force that drives plate motion on Earth?
Gravity
Magnetic fields
Solar radiation
Wind
