Galileo Galilei
Alfred Wegener
Isaac Newton
Albert Einstein
Which is more dense?
Continental Crust
Oceanic Crust
What happens to temperature and pressure as you get to deeper layers within Earth?
Temperature and Pressure increase
Temperature increases, Pressure decreases
Temperature decreases, Pressure increases
Temperature and Pressure decreases
This image here shows what type of boundary?
Divergent
Convergent: Subduction
Convergent: Collision
Transform
What do geologists notice about the rocks along the sea floor?
They get older as they get farther away from mid ocean ridges
They get thicker closer to continents
Density is impossible to measure
Youngest parts of the crust are along the continents
How do you calculate density?
Mass x Volume
Mass / Volume
Volume / Mass
Volume + Mass
If something floats in water, what can we say about its density?
It is more dense than the water
It is less dense than the water
It has the same density as water
The idea that the continents were once together, and separated over a long period of time is
Seafloor Spreading
Transform Boundaries
Continental Drift
Mid Ocean Ridges
Was was Wegener's hypothesis rejected?
He had no evidence for it
More detailed maps show that continents don't match up
No continents had similar fossils to support him.
He couldn't explain how the continents could be moved
Why is the upper mantle liquid, but the lower mantle is solid?
Upper mantle is hotter
Lower mantle is under higher pressure
Upper mantle is under higher pressure
Lower mantle is hotter
What kind of boundary is shown in this image?
Divergent
Convergent: Subduction
Convergent: Collision
Transform
Which of the following is not a feature we could expect near a convergent subduction boundary?
Volcanoes
Mid Ocean Ridges
Earthquakes
Ocean Trenches
Which of the following is a feature common with transform boundaries?
Volcanoes
Mountain chains
Ocean Trenches
Earthquakes
Where would you find most volcanoes that are on a continent?
Randomly scattered
In the middle
Along the coastlines (edges)
Most volcanoes are not on continents
What did Harry Hess propose about the mid ocean ridges?
Ancient aquatic creatures may still be alive there
The waters there should be very warm
The crust there should be old
The valley of the ridge are actual cracks within the crust
What was an important detail about the animal fossils Wegener saw had been discovered on different continents?
They were great swimmers when they were alive
They were from different periods of time
They wouldn't be able to swim across the ocean to get to other places
There were no similar fossils found on different continents
Which of the following is an example of a divergent boundary?
Great Rift Valley
Mt. Everest
Mt. Saint Helen
San Andreas Fault
Forms where plates are moving away from each other
Divergent
Convergent
Transform
Formed where two sections of Earth’s crust are colliding
Divergent
Convergent
Transform
The land mass where all of the continents were once together in one large continent is called ________________.
Laurasia
Pangaea
Eurasia
Gondwana
Tectonic plates consist of
continental crust
inner core
both continental and oceanic crust
oceanic crust
outer core
The fact that similar fossils are found on both sides of the ocean is evidence of
magnetic reversal
sonar
continental drift
plate boundaries
The movement of the tectonic plates is caused by
the rotation of the earth
convection currents in the Asthenosphere
the gravity of the core
the pressure of the atmosphere
Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that
the tectonic plates are moving away from each other
the continental crust is melting
the more dense oceanic crust is subducting
an ocean ridge is forming
Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that
