Fossils
The ancient remains of a prehistoric organism
What is a fossil?
The scientist who believed the continents were once all together and drifted apart
Who is Alfred Wegener?
A natural disaster caused by any plate boundary movement.
What is an earthquake?
Earth's outermost layer made of solid rock
What is the crust?
When two plates move toward each other
What is a convergent boundary?
The fossils of this ancient lizard that were found in South America and Africa
What is the Mesosaurus?
The name Alfred Wegener came up with for a super continent
What is Pangea?
A long, narrow, deep cut into the ocean floor.
(Hint: This gets created by subduction)
What is a trench?
Earth's innermost layer made of iron and nickel
What is the core?
When two plates move away from each other
What is a divergent boundary?
A scientist who studies fossils
What is a paleontologist?
Continental Drift
An underwater mountain range
What is a mid-ocean ridge?
The middle layer of Earth that is made of hot, slow-moving rock
What is the mantle?
When two plates rub against each other
What is a transform/slip boundary?

What is amber?
Alfred Wegener
Who is the scientist who came up with the theory of continental drift?
An area that surrounds the Pacific Plate and has a lot of volcanic activity
What is the Ring of Fire?
The layer that makes up Earth's plates
(Hint: it consists of the crust and a part of the upper mantle)
What is the lithosphere?
When one plate is pushed beneath another plate
What is subduction?
Fossils are found in this rock type
What is sedimentary?
4 pieces of evidence that Wegener used to argue that continental drift was true
What is:
Ancient Climate. The continents fit together like puzzle pieces. Landforms on different continents matched up. Fossils on different continents matched up on coastlines.

What is a cross-section?
The layer that helps the plates move
(Hint: it is in the upper mantle)
What is the asthenosphere?
Where two plates meet
What is a plate boundary?
