density
pressure
temperature
depth
2
Ancient Pangaea may have contained ____.
all of Earth's crust
all of Earth's oceanic crust
all of Earth's tectonic plates
all of the Earth's continental crust
3
What drives the movement of Earth's tectonic plates creating earthquakes and volcanoes?
the convection of ocean currents above the plates
the movement of Earth about its axis pulling on the plates
the movement of air currents pushing on the plates
the convection of magma under plates pulling them
4
A boundary where two tectonic plates come together or collide ____.
transform boundary
transfer boundary
convergent boundary
divergent boundary
5
What is a common secondary effect of a 9.0 magnitude earthquake?
a tsunami
global warming
a tornado
volcanic activity
6
Why do scientists believe more earthquakes will occur along the San Andreas Fault?
There has never been an earthquake at that fault line
It is the dividing line that may cause California to break
It is a major fault where pressure has been building
There is so much construction going on
7
Why have fossils been found in South Africa and South America but nowhere else?
In the future, both continents will be together again
Fossils evolved into different organisms
The climate changed to be much colder
Africa and South America may have been part of the same land
8
What part of a cracked hard boiled egg represents where earthquakes most likely occur?
at the top where the shell is pointed
along the smoothest part where pieces can't release stress
along the cracks where pieces rub against each other
at the bottom where the shell is the widest
9
Where should buildings be built to minimize earthquake damage?
In an area nothing is known about
At a moderate risk zone
At a severe risk zone
At a low risk zone
10
Plate tectonic describes movements that mainly occur in the ____.
Earth's mantle
Earth's outer core
Earth's crust
Earth's inner core
11
Which is true about Earth's 12-15 major tectonic plates?
Every tectonic plate contains a continent
Every tectonic plate contains oceanic crust
Every tectonic plate contains a continental crust
Every tectonic plate is spreading
12
Compared to continental crust, oceanic crust is ____.
lighter
denser
thinner
thicker
13
Continental-continental plate collisions produce ____.
deep rift valleys
small island arcs
tall mountain ranges
deep sea trenches
14
Scientist think the inner core is mostly composed of ____.
basalt
granite rock
molten iron
solid iron
15
Plate movement may be caused by convection currents located where?
in the crust
in the mantle
in the outer core
in the inner core
16
Why is an area of the world nicknamed The Ring of Fire?
Lithospheric plate boundaries are found in that area
It is hotter there than any where else
A lot of people live there
The weight of the water forces magma to the surface
17
A convection current of magma is made up of ____.
rising less dense liquid and more sinking dense liquid
liquids of the same density
rising more dense liquid and sinking less dense liquid
solids of different densities
18
How does magma pushing up in the Atlantic Ocean changing the ocean floor?
it produced flat, smooth ocean floor as continents separate
created a long, mountain range below the ocean's surface
produced volcanoes along edges of continents
made the Atlantic Ocean waters warmer
19
Which accurately describes the relationship between earthquakes and volcanoes?
Earthquakes and volcanoes are not related in any way
Earthquakes usually cause volcanoes to erupt
Volcanic eruptions usually cause severe earthquakes
They are often located where tectonic plates meet
20
Areas that lie above the borders of tectonic plates are characterized by ____.
frequent earthquake activity
lengthy formations of sea arches
lack of plant life and animal life
stable temperate climate conditions
21
If 2 plates meet at convergent boundaries and DO NOT subduct, what can happen?
they fold and crumple
they erupt
they make a fault
they weather
22
What was Alfred Wegener's hypothesis?
the continents will one day form another large land mass
the continents have always been where they are now
the continents were part of a large land mass that split
the continents are made of rock
23
Earth's geography has been affected by _____
alluvial fans
global warming
tectonic movement
subduction zones
24
Why are there many earthquakes along the Pacific Coast?
plate movement
gravity
solar heating
erosion
25
Where is the thickest layer of the earth located?
inner core
crust
outer core
mantle
