1
Which of the following is NOT a benefit of volcanoes?
solar power
rich soil for farming
geothermal energy
increased tourism
2
Why do people choose to live around the Ring of Fire?
The mineral resources help the economy.
There is rich soil for farming.
Volcanoes attract tourists, which helps the economy.
They like to feel like they're in danger.
3
Along certain plate boundaries magma comes to Earth's surface to form new rock. Why?
rising currents in the mantle
sinking currents in the mantle
the rotation of Earth's core
Earth's magnetic field
4
What movement is found along a transform boundary?
side-by-side movement of two plates
two plates moving away from each other
two plates moving towards each other
one plate moving over the other
5
What do scientists believe causes the tectonic plates to move?
wind currents in the atmosphere
convection currents in the mantle
vehicles moving around on Earth's surface
the core being made of iron and nickel
6
What happens at the mid-ocean ridge?
It is the beginning of the beach area.
Two plates converge.
Island chains are constantly forming.
Two plates diverge, creating new crust.
7
Where are MOST volcanoes and earthquakes found?
in the tropics
in the middle of continents
in the middle of tectonic plates
along the edges of tectonic plates
8
Where does the heat energy that drives convection currents in the mantle come from?
Earth's core
the summer sun
the burning of fossil fuels
air currents above Earth's surface
9
What do scientists study to predict what the Earth's interior is made of?
plants & trees
fossils & rocks
magma & seismic waves
continents & oceans
10
What made Wegener first believe that the continents had once been together?
He found fossilized human remains to prove his theory.
He measured sea-floor spreading.
He noticed the shapes of the continents seemed to match.
He found igneous rocks in Europe.
11
What type of fossil supports the theory of plate tectonics?
a fossil that is very young
a fossil that is very old
a marine organism found in different oceans
a land organism found on continents separated by oceans
12
What is Pangaea?
the former name of North America
A supercontinent that existed 300 million years ago
one of Earth's plates
a type of volcano
13
Why did other scientists not accept Wegener's theory of continental drift at first?
He could not explain how the continents move.
The continents were not moving at that time.
The shape of the continents did not match up.
The continents were moving too fast to measure.
14
What movement is found at a convergent boundary?
two plates moving diagonally
two plates moving towards each other
two plates moving side by side
two plates moving away from each other
15
The tectonic plates are floating on material that is moving in Earth's ______________.
mesosphere
inner core
outer core
mantle
16
What are two natural effects of movement along transform boundaries?
earthquakes & fault lines
rifts & island arcs
mountains & volcanoes
valleys & trenches
17
What evidence was found later to support Wegener's theory of continental drift?
human remains
the composition of the Earth's core
fossils, rocks, & glacial deposits
earthquakes & volcanic eruptions
18
Rifts, mountains, and faults are all created by ______________________.
divergent boundaries
activity along boundaries
human activity
earthquakes
19
Which of the following is NOT evidence for the theory of plate tectonics?
sea-floor spreading along mid-ocean ridges
meteorite craters in locations around the world
earthquakes and volcanoes occur along specific zones
the coastlines of South America and Africa match up
20
What theory explains why we see the same prehistoric fossils on different continents?
The Ring of Fire
continental drift
physical weathering
continental evolution
21
Subduction zones usually form where __________________________.
an oceanic plate collides with a continental plate
there is a really big plate
two continental plates collide
two oceanic plates are moving apart
22
Which of the following is a benefit of earthquakes?
They push minerals and metals closer to the surface.
They cause more volcanic eruptions.
They cause massive destruction.
They make the plates move correctly again.
23
What can convection currents cause?
They can form solid rocks.
They can cause cementation of rock material.
They can cause sea-floor spreading.
They can cause the Earth to spin.
24
What is the theory of plate tectonics?
a theory about the origin of North America
the name for a layer of sedimentary rock
a theory about Earth's origin
a theory that Earth's crust is broken into pieces that move
25
How is the crust of the Earth broken up?
seismic plates
tectonic plates
states
fault plates
26
How do scientists know how far the plates are moving every year?
They measure changes in rock formations along boundaries.
They measure changes in boundaries (ex. San Andreas fault).
They measure how deep fossils are in the Earth.
They take aerial pictures changing landscapes.
27
What did Alfred Wegener propose in his theory of continental drift?
Earth is expanding
the continents were once joined together in one land mass
the continents are floating around on a large ocean
the continents are all moving together and will soon collide
28
What are scientists NOT doing to help prevent the devastation caused by earthquakes?
