Boundaries
This type of plate boundary is formed when two plates slide past each other horizontally
What is a transform boundary?
This is the outermost and thinnest layer of the Earth, where we live.
What is the crust?
This scientist proposed the theory of continental drift in the early 20th century.
Who is Alfred Wegener?
Sudden releases of energy in the Earth's crust, resulting in seismic waves and shaking of the ground, are known as these geological events.
What are earthquakes?
Frosting represents which layer of the Earth?
What is the mantle.
At this type of plate boundary, two plates move apart from each other.
What is a divergent boundary?
This layer of the Earth is located between the crust and the outer core.
What is the mantle?
The supercontinent that existed about 300 million years ago and eventually broke apart to form today's continents is called this.
What is Pangaea?
These are fractures in the Earth's crust where movement has occurred, often causing earthquakes.
What are faults?
A Graham cracker represents which layer of the Earth?
What is the crust?
At this type of plate boundary, two plates move towards each other and collide.
What is a convergent boundary?
This layer of the Earth, located beneath the mantle, is divided into an outer layer that is liquid and an inner layer that is solid.
What is the core?
Name one evidence that supports Continental Drift.
What are fossils, mountain ranges, ancient climatic zones.
This type of fault occurs when the hanging wall moves downward relative to the footwall.
What is a normal fault?
There are _____ continents.
What are 7.
This type of convergent boundary results in the formation of large mountain ranges.
What is convergent boundary.
As you travel deeper into the Earth's layers, this property increases.
What is temperature?
Today's continents continue to slowly move due to plate tectonics at a rate of approximately this many centimeters per year.
What is a few centimeters per year?
In this type of fault, the hanging wall moves upward relative to the footwall.
What is a reverse fault?
This is the continent we live on.
What is North America.
At this type of boundary, the denser oceanic plate sinks beneath the lighter continental plate.
What is subduction zone/convergent boundary.
This famous fault in California is responsible for numerous earthquakes in California.
What is the San Andreas Fault?
Fossils found in both South America and Africa support the theory of continental drift because:
What is they suggest that these continents were once connected?
This type of fault occurs when the two blocks slide past each other horizontally.
What is a strike-slip fault?
This continent use to be hot.
What is Antarctica.
