Answers

1
Why is there no subduction at continental to continental convergent boundaries?
Because continental crust is too dense to subduct
Because there is no plate movement at this boundary
Because it is a spreading center
Because continental crust has low density
2
True or False: Puzzle evidence was one of the pieces of evidence for continental drift.
False
True
3
What are the different types of plate boundaries?
spreading, compositional, & transitional
divergent, convergent, & transform
lithospherie, asthenosphere & mesosphere
oceanic & continental
4
Which has the lowest density?
core
oceanic crust
continental crust
mantle
5
The San Andreas Fault is an example of
a transform plate boundary
a minor fault adjacent to a plate boundary
a divergent plate boundary
a convergent plate boundary
6
True or False: Plate tectonics is responsible for all the Earth's mountain ranges.
True
False
7
What layer of the Earth facilitates plate movement?
asthenosphere
mesosphere
outer core
lithosphere
8
What is paleomagnetism?
The repeated switching of the magnetic north pole over time
Use of magnetic compasses during paleolithic times
A good diet to lose weight
the underwater mountain range that is across the globe
9
True or False: The lithospheric plates have stopped moving.
False
Maybe?
True
We do not know.
10
How do scientists know that the Earth's outer core is liquid?
The shadow zone caused by the bending of Earthquake waves.
The presence of the Earth's magnetosphere.
They discovered it when they drilled down to the core.
They x-rayed the Earth.
11
What would happen if the Earth cools?
Nothing would change
Life would thrive because volcanoes & earthquakes would stop
Life would thrive because global warming would stop
Life would die out because of the loss of the magnetosphere
12
Plate Tectonics is a theory because...
It is unproven
It describes plate movement and its effects
It explains plate movement and its effects
It does not have evidence to support it
13
In which direction would the red end of a compass point during a magnetic reversal?
West
North
East
South
14
How have continents grown larger?
Accretion of terranes in the center
Formation of new land on the edges through volcanoes
Volcanoes forming new land in the center
Accretion of terranes along the edges
15
Is Albuquerque on a plate boundary?
Yes, it is on a divergent boundary that is forming currently
Yes, it is a continental convergent boundary
Yes, it is on the Rio Grande Rift
Yes, it is a continental divergent boundary
16
True or False: Plate tectonics is necessary for life on Earth
True
False
17
Subduction is to ________, as sea-floor spreading is to ________.
slab pull, ridge push
divergent, convergent
convergent, divergent
ridge push, slab pull
18
In convection,
less dense material rises and more dense material sinks
more dense material rises and less dense material sinks
heat does not play a role
density does not play a role
19

True
False
20
Iceland is an example of ...
An oceanic to oceanic convergent boundary
an oceanic divergent boundary
a continental to continental convergent boundary
An oceanic to continental divergent boundary
21
What is the lithosphere?
the top-most structural layer of the Earth
the top-most compositional layer of the Earth
the middle compositional layer of the Earth
the fluid, plastic-like layer that is beneath the crust
22
True or False: Volcanoes can be found at all plate boundaries
True
False
23
What is the name of the volcanoes that form a u-shape distribution around the Pacific Plate?
Ring of Fire
Volcanic Ring
Ring of Volcanoes
Volcanic U
24
What causes plate tectonics?
Conduction from the Earth's core
Convection currents in the Earth's mantle
The force of gravity from the moon.
Radiation from the sun
25
What evidence is there that oceanic crust is younger than continental crust?
the presence of a long mountain range in the ocean floor
None, it isn't younger
paleomagnetism
thicker oceanic crust in the middle than at the edges
26
When looking at a map that shows earthquakes on Earth, what is obvious?
Nothing
That outline of lithospheric plates
The earthquakes form a random pattern
That earthquakes are rare
27
What is Pangaea?
The first supercontinent
The only known supercontinent
The most recent supercontinent
The name of Eurasia in the past
28

climate evidence
seafloor spreading evidence
geologic evidence, such as mountain ranges & deserts
fossil evidence
29
Where are the oldest rocks on Earth found?
At the edges, as remnants of supercontinent breakup
No where, because they were all destroyed when Pangaea split
At the center, as remnants of the first continents
On the Earth's surface, brought up by volcanic eruption
