Geologic Change
This was the supercontinent that existed roughly 235 million years ago.
What is Pangea?
This is the plate boundary that has two plates moving towards each other.
What are convergent boundaries?
This is the type of plate boundary where two plates are moving away from each other.
What are divergent boundaries?
This is how resources are distributed around the world.
What is uneven distribution?
This is the most geologically active region around the world.
What is the Ring of Fire/ Along the edges of the Pacific Ocean?
These are what form in the ocean where two oceanic plates move apart.
What is a mid-ocean ridge?
This is the current in the asthenosphere that causes the Earth's tectonic plates to move.
What is convection?
This is the type of plate boundary where two plates slide past each other in different directions.
What are transform boundaries?
These are what cause the uneven distribution of resources.
What are geologic processes?
This is how many boundary types there are.
What is 3? (Convergent, Divergent, and Transform)
This is what creates volcanoes in the middle of a tectonic plate.
What is a hot spot?
This is where you can best see the effects of tectonic plate movements.
Where are plate boundaries?
This is the region where the more dense plate is forced underneath the less dense plate.
What is a subduction zone?
This is the fresh water we find below the Earth's surface.
What is groundwater?
This is a line of evidence that suggests that the continents were once together.
What are fossils, the shape of the continents, or rock layers? (You only needed to name one)
This is the process that creates mountains at plate boundaries.
What is uplift?
This is the thinner, more dense part of the Earth's crust.
What is oceanic crust?
This is the thicker, less dense part of the Earth's crust.
What is continental crust?
These are the fossil fuels found in the Appalachian Mountains.
What are coal and natural gas?
This is what Wegener called his theory for how the continents had moved from Pangea to their current locations.
What is Wegener's Theory of Continental Drift?
This is what you call a crack or fracture in the Earth's crust.
What is a fault?
This is how fast tectonic plates move.
What is the speed your finger nails grow at?
This is where active volcanoes are most likely to form at.
What are convergent boundaries?
This is the amount of water on earth that is fresh water.
What is 3% of the Earth's water?
This is how convection works.
What is warmer less dense material rising and cooler more dense material sinking?
