Fossils
What are the remains or traces of ancient organisms preserved in rock called?
Fossils
What is the theory that explains the movement of Earth's plates?
Convection Currents
What type of plate boundary occurs where two plates move apart?
Divergent!
This feature is created when two plates collide causing land to be lifted up, not volcanic!
Mountains
The idea that the continents of today are a broken up version of a supercontinent is called what theory?
Continental Drift Theory!
Can plants be fossilized?
Yes!
What is the type of boundary by which new oceanic crust is created at mid-ocean ridges?
Divergent Boundary
What type of boundary occurs when plates move TOWARD each other?
Convergent Boundary!
What type of boundary creates rift valleys?
Continental-Continental Divergent
These large sections of Earth's crust move slowly over the mantle and cause earthquakes, volcanoes, and mountain formation.
Tectonic Plates
How can fossils found on different continents support the theory of continental drift?
Similar fossils on different continents provide evidence that the plates were together!
What evidence supports the theory of plate tectonics?
Rock Strata, Continents fit together, fossils
This type of boundary is known for the largest earthquakes
Transform Boundary!
A trench is created when a continental plate and an oceanic plate do this
Converge!
Earth used to have one large Supercontinent known by the name of
Pangea
The Mesosaurus, a river reptile, is theorized to live on which two continents that are now separated by a large ocean.
Africa and South America
What is the scientific name for the layer below the lithosphere (crust)?
Asthenosphere!
Which type of continental crust is known for being thick and LESS dense?
Continental Crust!
This feature forms when a plate subducts, creating a lot of friction and a lot of heat
Volcanoes!
Mount Everest has sea animal fossils on its peak, this indicates that Mt. Everest used to be located where?
Underwater
Fossils of Glossopteris, a plant, found in Antarctica, India, and Africa; indicate that Antarctica was once what?
Warm or Tropical!
They will cause the continents to move!
Which two types of curst create a Mid-Ocean Rift when they move away from each other?
Oceanic-Oceanic!
The Himalayas, home to Mt. Everest, was created because of what type of plate boundary? (Double points for the type of crust included)
Continental-Continental Convergent
When Pangea broke up, it first broke up into these two smaller Super Continents
Laurasia and Gondwanaland
