1
Scientists have found that rocks closer to the mid-ocean ridge are ___________________ than those further away.
far from volcanic activity
cooler rocks
less dense
more dense
2
Which type of plate boundary is found where "sea floor spreading" happens?
Transform
Convergent
Subduction
Divergent
3
How did the Appalachian Mountains in North America and the Atlas Mountains in North Africa provide evidence for Pangea?
Neither range contained fossils prevalent near the equator
Neither had rock layers similar to the mountains found nearby
Both ranges had similar types, ages, and sequences of rock layers
Both ranges are comprised of a diverse assortment of rock types
4
The Pacific ___________ is a region of heavy volcano and earthquake activity.
Ring of Fire
Circle of Volcanoes
Earthquake Zone
Lava Circuit
5
Which of the following statements about oceanic crust recycling is true?
Crust gets hotter as it's older, floating over new crust that is destroyed
Crust recycled at mid-ocean ridges where two plates crash into each other
Scientists no longer believe crust gets recycled
The old crust in ocean trenches sinks into the mantle where it is destroyed
6
The crust beneath oceans, _________ crust, is thinner than the crust beneath continents, __________crust.
marine; terrestrial
water; land
oceanic; continental
aquatic; rocky
7
Which type of boundary is where trenches are formed?
Divergent
Convergent
Transform
Seafloor Spreading
8
A ___________ is a well-established group of ideas or models this is supported by a large amount of evidence.
Scientific Theory
Hypothesis
Criteria
Question
9
Rocks near mid-ocean ridges are _________ rocks further away. This phenomenon is due to a process called __________.
a different type from; deposition
younger than; seafloor spreading
older than; seafloor converging
the same age as; weathering
10
A statement that’s accuracy can be tested by experiments and through observations is formally called a _______________.
deduction
hypothesis
conclusion
proposition
11
Which of the following statements is NOT true of seismic waves?
As they pass through rocks of different densities they change direction
Studying seismic waves helps scientists study the Earth’s interior
Seismic waves travel at the same speed regardless of rock density
Seismic waves are vibrations that result from earthquakes
12
What statement below BEST explains why a convergent boundary is “destructive"?
As plates move away from each other, crust spreads and new crust upwells.
As plates collide, valleys form & fill with water causing a loss of land.
Plates slide past each other, creating a transform fault & material erodes.
As one plate subducts it melts into magma.
13
The process of _________ occurs when large landmasses move, like when Pangea broke apart.
landmass movement
plate shift
continental drift
land transference
