Boundaries
what is a divergent boundary?
where two plates move apart or diverge
what is a convergent boundary?
where two plates come together, causing a collision where one plate is subducted
What is the name of the SUPER continent?
Pangea.
Name one event that can cause mass extinction.
Meteor impact, volcanic eruption, climate change.
Coal, oil, and natural gas are examples of this type of resource.
Nonrenewable.
what is a transform boundary?
where plates slide past one another moving in opposite directions
where two plates meet
Most fossils are found in this type of rock.
Sedimentary.
This rock is made from cooling and crystallization?
Igneous Rock
This type of weathering changes the chemical makeup of rock?
Chemical weathering.
what is subduction?
when one plate slides under another
This is the process in the mantle that drives plate movement.
Convection Currents
This law states that in undisturbed rock layers, the oldest layer is on the bottom.
The law of Superposition.
Evolution is the ______ change in species over time.
Gradual or Slow.
Name one advantage of renewable energy.
Less pollution / sustainable / reduces greenhouse gases.
What 2 geological features is created by Divergent Plate Boundary?
Rift Valleys & Mid - Ocean Ridge
what is one geological feature that is created by a transform boundary?
earthquakes
If two fossils share similar bone structures but lived millions of years apart, what does this suggest?
They share a common ancestor.
Why don’t fossils usually survive in igneous rock?
Heat from magma destroys them.
Name one disadvantage of renewable energy.
High cost / weather dependent / storage challenges.
what is a real life example of a transform boundary?
the san andreas fault
what 2 geological features can be created by Convergent plate boundary?
mountains & volcanoes
A fault cuts through several rock layers. What does this tell you about the fault compared to the layers?
The fault is younger than the layers it cuts through.
Explain how the rock cycle both preserves and destroys fossils.
Sedimentation preserves fossils; heat, pressure, and melting destroy them.
This tool measures ground motion during earthquakes.
Seismograph.
