Total questions: 16
Worksheet time: 8mins
What scientist first proposed the Theory of Continental Drift
Alfred Wegener
Charles Darwin
Gregor Mendel
Charles Lyell
Which of the following is NOT evidence that supports the Theory of Continental Drift?
Fossils
Similar Rocks and Landforms
Salinity of the Oceans
Continental Fit (fit like puzzle pieces)
What process causes the continents (Plate Tectonics) to move?
High Tide
Ocean Currents
High Pressure systems
Convection currents in the Mantle/Asthenosphere
Where are the convection currents that move the continents found?
Crust
Mantle
Outer Core
Inner Core
How did fossil evidence (the same species was found on multiple continents) support the Continental Drift theory?
It showed that animals crossed landbridges
It showed that the continents must have been together
It showed animals evolved independently of each other.
It showed that animals must have swam great distances.
What layer of the earth is broken in to tectonic plates that move?
Lithosphere
Asthenosphere
Inner Core
Outer Core
Which layer of the earth flows really slowly like putty?
Crust
Asthenosphere
Inner Core
Lithosphere
Is the outer core of the earth liquid or solid?
Liquid
Solid
Which layer of the earth is responsible for creating the magnetic shield that protects the earth and its atmosphere?
Outer Core
Inner Core
Crust
Mantle
What is a Magnetic Reversal?
When the earths magnetic poles switch
When the earth physically turns upside down
When the sea floor spreads apart
When the Earth tilts more than usual
How do we know that magnetic reversals happen?
Humans and animals can feel it
Rocks near mid-ocean ridges "record" the direction of the poles
The atmosphere disappears
We can't see the sun
What do we call underwater mountain ranges that are formed where 2 tectonic plates are spreading apart?
Mid-Ocean Ridges
Underwater Mountains
Mid-Water Mountains
Under-water Ridges
What is the process that creates new oceanic lithosphere as the older lithosphere is pulled away from each other?
Sea-floor Spreading
Lithosphere Creation
Magnetic Reversals
Crust Renewal
What is an additional piece of evidence that supports the theory of plate tectonics?
Sea-Floor Spreading
Atmospheric Changes
Animal Migration Patters
Ocean Salinity
Is the inner core of the earth liquid or solid?
Liquid
Solid
Put the layers in order from the center of the Earth outward.
