rift valleys
8
What does the moment magnitude scale measure?
the energy released by an earthquake
the risk of future earthquakes
the amount of time between earthquakes
the amount of shaking caused by an earthquake
9
What sign would indicate that a volcano might erupt soon?
heating of nearby groundwater
snow on top of volcanic mountain
decrease in temperature of nearby groundwater
sunken areas of land
10
How do island arcs form?
when oceanic crust collides
when oceanic crust diverges

13
What material are Earth's inner and outer core made of?
rock
solid
metal
liquid
14
Hot springs that erupt and send hot water shooting into the air are called
deep sea vents
geysers
trenches
fumaroles
15
An opening through which lava, rocks, and gases erupt is called a
plate boundary
trench
fault line
volcano
16
Why do scientists monitor volcanoes?
to learn about Earth's atmosphere
to find out what Earth's core is like
to stop them from erupting
to predict when they might erupt
17
What aspect of an earthquake can scientists usually predict?
the earthquake risk of an area
the amount of damage an earthquake will cause
the exact location of an earthquake
the exact time of an earthquake
18
What type of wave is caused by an earthquake on the ocean floor?
tsunami
primary
longitudinal
seismograph
19
Where do most volcanoes occur?
on high mountains
along plate boundaries
over hot spots
in North America
20
Why do most earthquakes occur at tectonic plate boundaries?
the boundaries are very strong
there is more movement along the boundaries
the boundaries are over hot spots
there is less movement along the boundaries
21
Which layer of earth contains the tectonic plates?
outer core
inner core
lithosphere
asthenosphere
22
How does the age of oceanic crust at a mid-ocean ridge compare to crust at a trench?
it is the same everywhere
it is younger at the mid-ocean ridge
it is older at the mid-ocean ridge
it is younger at the trench
