Answers
1
Magma’s cycle of heating, rising, cooling, and sinking is called a _____________.
convergent boundary
transform fault
subduction zone
convection current
2
Continental drift was not widely accepted when it was first proposed because
continents were too big to move slowly over Earth’s surface.
why and how the continents moved could not be explained.
magnetic and sonar data suggested that it was incorrect.
mantle convection currents weren’t active until recently.
3
Who began the theory of plate tectonics with his theory called continental drift?
Alfred Wegener
Edwin Hubble
Copernicus
Isaac Newton
4
The existence of coal deposits in Antarctica indicates that the continent was once
part of Africa
cold & dry
swampy with dense vegetation
far from the equator
5
A mountain range, like the Himalayas, are forming as a result of
continental - oceanic convergence
continental - continental convergence
oceanic - oceanic convergence
none of the other choices is correct
6
Which of the following forms when an oceanic plate collides with a continental plate?
a rift zone
subduction zone
an island
magnetic reversal
7
What are tectonic plates?
slabs of crust and upper mantle
slabs of continental crust
slabs of oceanic crust
mantle material
8
What do scientists believe is the force behind the plate tectonics theory?
the movement of the planets
the Sun's gravity
gravity slab pull
convection currents
9
Most of the planet's volcanism occurs
within mountain ranges.
along continental margins.
along mid-ocean ridges.
toward the interior of lithospheric plates.
10
Ocean plates are __________ than continental plates.
thicker
less dense
lighter
more dense
11
The San Andreas Fault is a
transform fault boundary
subduction zone
convergent boundary
divergent boundary
12
What is the difference between lava and magma?
They originate from different places
They are made of different types of rock
They are different colors
After magma reaches Earth’s surface it is called lavad
13
Convection currents in the Mantle cause cooler, denser material to;
become lava
sink deeper into the mantle
rise to the top of the asthenosphere
form into solid rock
14
What do we call boundaries along which plates are moving apart?
transform fault
convergent
convection current
divergent
15
Which of the following is a plate boundary where two plates slide past each other?
transform fault
divergentd
volcanic
convergent
16
When oceanic crust collides with continental, all of the following can happen -
except
?
There is a subduction zone
Crust is recycled
There is a transform boundary.
There are mountains formed
17
Where is new oceanic crust formed?
subduction zone
the asthenosphere
transform fault boundary
mid - ocean ridge
18
The layer of the Earth located just beneath the crust is called the
lithosphere
inner core
outer core
mantle
19
Where is the oldest oceanic crust is found?
in the middle of the plate
nearest the subduction zone
in the shallowest part of the ocean
nearest the mid-ocean ridge
20
How do temperature and pressure change with depth in the Earth’s crust?
ask Einstein
they increase
they remain the same
they decrease
