Answers
1
Where does most of Earth's seismic activity occur?
along mountain ranges
along the edges of continents
along tectonic plate boundaries
along stream valleys
2
The oceanic plate in this image
sinks
because
of magma chambers
that crust is more dense
It's less dense
it's new crust
3
What forms at a CONVERGENT
oceanic
and
continental
plate boundary?
trenches
ridges
rifts
(non volcanic) mountains
4
Along what type of plate boundary might a mountain range form?
convergent
transform
fault
divergent
5
Which type of tectonic plate occurs where they are moving apart from each other?
a transform boundary
a strike-slip boundary
a divergent boundary
a convergent boundary
6
The area where the heavier basalt ocean plate sinks is called what?
a mid-ocean ridge
subduction zone
a transform fault
a magma chamber
7
Which of the following best describes convection?
Energy from the magma touch the surrounding rock
differences in the composition of magma causes movement
hot rock material flows upward, cools, then sinks
Particles collide transferring heat energy
8
Which of these facts is NOT TRUE about volcanoes?
Magma is a gas that erupts on earth's surface
Volcanoes erupt molten material out of vents on surface
volcanoes form near tectonic plate boundaries
lava is magma that flows onto Earth's surface
9
Which of these pieces of evidence does NOT support Wegener's hypothesis?
climates at different latitudes are similar to each other
fossils are found on different continents
Similar glacier sediments found in different parts of world
Continents seem to fit together
10
Which of the following causes the movement of Earth's tectonic plates?
convection of magma from the core of earth
large faults in mountain ranges
energy released from volcanic activity
conduction of Earth's core
11
Which feature usually forms along a
divergent
plate boundary
ABOVE
the ocean?
a rift valley
an ocean trench
a fault-block mountain
a chain of volcanoes
12
These volcanic arc islands formed as a result of...
2 oceanic plates colliding
earthquakes on oceanic boundaries
2 DIVERGENT oceanic plates dividing
2 convergent contenential (LAND) plates colliding
13
What is a fault?
a hot spot in the lithosphere
a landform formed by volcanic activity
breaks in Earth's upper crust
a break or crack in the core of Earth

hot spot
convergent
18
How do mid-ocean ridges form?
Earthquakes on the ocean floor.
ocean plates colliding
ocean plates divided by magma and convection
plates moved toward each other
19

20
Which theory explains why land masses are on the move?
the theory of subduction
the theory of gravity
the theory of convection
the theory of plate tectonics
21
Why do many earthquakes happen in the Ring of Fire around the Pacific Ocean?
many ocean trenches are located around the basin
the high number of tectonic plate boundaries
tides around the Ring of fire
two plates are diverging in the Pacific Ocean basin
