Catch my Drift?
The German scientist who came up with the idea that the continents have drifted over time and used to be a supercontinent called Pangaea
Who is Alfred Wegener?
This plate boundary is when two plates slide past each other, causing a fault line and earthquakes
What is a transform boundary?
What is blue?
What is elevation?
This evidence for continental drift involved finding bones of animals from long ago lining up across continents
What is fossils?
What is continental drift theory?
When two continental crusts move towards each other, building upwards and making mountains
What is convergent boundary with collision?
The name of Mr. Urby's dog
What is Kirby Urby?
Contour lines symbolize this on a topographic map
What is areas of equal elevation?
This evidence for continental drift is the most obvious: Just look at South America and Africa
What is continental fit?
This theory helped explain how the continents drift
What is seafloor spreading?
Describe a divergent boundary
What is a boundary where two plates move away from each other?
A hobby of Mr. Urby's
The closer the contour lines, the ________ the slope.
What is steeper?
The Appalachian mountains are an example of this
What are landforms that go across multiple continents
The name of the theory that combines continental drift and seafloor spreading
What is plate tectonics?
The landforms possible from a divergent boundary
What is mid ocean ridge (if plates are oceanic) or rift valley (if plates are continental)?
Mr. Urby has this many children
What is 2
The change in elevation between each contour line is called what
What is contour interval?
Glacial evidence for continental drift specifically refers to this
The scratches (striations) going across multiple continents, or the evidence of glaciers on continents that are warm now
The term seafloor spreading is best used to describe this
What is magma coming up along a mid-ocean ridge?
When an oceanic plate slides towards a continental plate and slides under, causing volcanoes and a trench
What is convergent boundary with subduction?
The total number of siblings Mr. Urby has
What is 19?
An easy way to determine the contour interval of a topographic map
What is look for two index lines near each other, subtract them, and then divide by the number of spaces between them
All three pieces of evidence for seafloor spreading
What is magma rock, drilling samples, and magnetic striping?
