The thin, solid, outermost layer of Earth above the mantle.
What is the crust?
The principle that younger rocks lie above older ones if undisturbed.
What is superposition?
A fossil used to determine the age of a rock layer.
What is an index fossil?
Group Activity: Pair up with another student and “push” your hands together slowly to model two plates colliding and rising. What is created from this activity?
What are mountains?
The U.S. park that sits on a supervolcano.
What is Yellowstone?
A vent or fissure in Earth’s surface through which magma and gases are expelled.
What is a volcano?
These circular motions in the mantle push tectonic plates.
What are convection currents?
The layer of rock between Earth’s crust and core.
What is the mantle?
Group Activity: In your group, physically demonstrate the 3 boundary types and name them.
What are divergent, convergent, and transform boundaries?
Movement along this feature releases stored energy as earthquakes.
What is a fault?
A sudden shaking of the ground caused by rocks moving along a fault.
What is an earthquake?
Long depressions formed on land at divergent boundaries.
What are rift valleys?
A supervolcano eruption can change global __________
What is climate?
Group Activity: Start grouped together and slowly spread apart across the classroom. What is this process called?
What is continental drift?
At a divergent oceanic boundary, new crust is formed through __________.
What is seafloor spreading?
The solid, outer layer of Earth that includes the crust and rigid upper mantle.
What is the lithosphere?
A volcanically active area far from plate boundaries.
What is a hot spot?
The majority of earthquakes on Earth occur at this type of plate boundary.
What are transform boundaries?
Group Activity: Two people pull apart their arms slowly while another raises their arms to represent magma rising. What is this process called?
What is the formation of Mid-Ocean Ridges.
When two tectonic plates collide, Earth’s crust is __________.
What is destroyed?
A large elevated landform, usually rising to a summit.
What is a mountain?
The theory that Earth’s outer layer is made of large, moving pieces.
What is plate tectonics?
Large depressions on Earth’s surface filled with seawater.
What are ocean basins?
Group Activity: Use slow, circular hand motions while moving around your table to represent how plates move. What is this process called?
What is convection currents?
Rare, massive eruptions that can disrupt climate and cause mass extinctions.
What are supervolcanoes?
