Earths crust is broken into large pieces
called

The theory that the continents have moved so far
over millions of years that they had to have
once been connected is
Contintental Drift
5
The point on the surface above where an
earthquake starts, where the earthquake is
usually felt the most is
epicenter

What type of volcano forms from layers of ash
and lava from both quiet and explosive
eruptions?
composite
9
The ring of fire is an area around the Pacific
plate where subduction has caused a lot of
volcanoes
10
A machine that records the vibrations of an
earthquake is a
seismograph
11
What type of volcano forms from thin layers of
lava from quiet eruptions?
shield volcano
12
This part of a volcano is a large pool of hot
molten rock from the mantle.
magma chamber
13

• Which type of plate boundary can
• weaken the crust and form volcanoes?

subduction
14
If an island volcano collapses in, it can
create a
atoll
15
This part of a volcano is the narrow crack that
brings magma to the surface.
pipe
16
Which type of plate boundary can cause
earthquakes?
Transform / sliding
17
What do we call the strength of an earthquake?
the magnitude
18
What evidence was found to prove that there
really used to be a supercontinent?
fossils
19
What do we call a volcano that is still likely
to erupt?
active
20
Which kind of fault creates mostly sideways
shaking?
strike-slip
21
The hot, molten rock that makes up the mantle is
called ________ once it reaches the surface
lava
22
Magma trapped under the surface can create a
bulge of rock called a
dome mountain or volcanic bulge
23
What do we call a volcano that is not likely
to erupt ever again?
extinct
24
Wegener called the supercontinent before the
continents drifted apart
Pangea
25
Earths surface can be changed by
earthquakes, volcanoes, tsunamis, rivers,
glaciers, tectonics
26
The hot, molten rock that makes up the mantle is
called
magma
27
What scale for rating earthquakes do most
people use today?
Richter scale
28
What happens when colliding ocean and continent
plates weaken the crust, and magma breaks
through?
a volcano forms
29
The crater of a volcano can collapse, forming a
larger crater called a
caldera
30
What do we call a volcano that has not erupted
in a long time?
inactive or dormant
31
Water trapped underground and heated by nearby
magma can build up pressure and form a
geyser
32
This part of a volcano is the bowl shaped mouth
of the volcano.
crater
33
A break in the crust from plates sliding is
called a
fault
34
Which kind of eruption has thick, sticky lava
that clogs the pipe and builds up pressure?
explosive eruption

lava that oozes and pours out of the vents?
quiet eruption
40
The point where sliding plates catch and cause
an earthquake is the
focus
41
The study of the movement of Earths crust is
tectonics
