Answers
1
Why do California and Alaska have more earthquakes that Ohio and Florida?
Ohio and FLorida are located near tectonic plate boundaries
Thicker continental crust reduces earthquakes
Coastal areas have more earthquakes
California and Alaska are near tectonic plate boundaries
2
Where does most of Earth's seismic (earthquake) activity occur?
along mountain ranges
along stream valleys
along tectonic plate boundaries
along the edges of continents
3
What event happens in a transform boundary?
an eruption
an earthquake
a convection zone
a storm surge
4
The result of a continental plate and an oceanic plate colliding.
mid-ocean ridges
volcanic mountains
arc islands
folded mountains
5
What feature of plate tectonics is happening in the illustration?
a mid-ocean ridge
a magma chamber
subduction zone
a transform fault
6
His discovery of the mid-ocean ridges lead to the idea sea floor spreading. Continents ride on
Charles Darwin
Harry Hess
Albert Einstein
Alfred Wegener
7
The feature created by two continental plates converging.
A volcanic mountain
A Rift Valley
A folded mountain
A mid-ocean ridge
8
The reason continental plates ride on top of oceanic plates and do not subduct
They occulate
They are less dense
They are lighter
They are heavier
9
The feature created by two continental plates diverging.
A mid-ocean ridge
A Rift Valley
A volcanic mountain
A fold mountain
10
Which of the following causes the movement of Earth's tectonic plates?
energy released from volcanic activity
conduction of Earth's core
large faults in mountain ranges
convection currents in the Earth's mantle
11
What plate boundary does the illustration show?
divergent
convergent
transform
ridge
12
Which of these pieces of evidence does NOT support Wegener's hypothesis?
fossils are found on different continents
Similar glacier sediments found in different parts of world
Continents seem to fit together
climates at different latitudes are similar to each other
13
Which theory explains why earthquakes and volcanoes occur?
the theory of subduction
the theory of gravity
the theory of plate tectonics
the theory of convection
14
Along what type of plate boundary might a mountain range form?
divergent
convergent
fault
transform
15
Why do many earthquakes happen in the Ring of Fire around the Pacific Ocean?
two plates are diverging in the Pacific Ocean basin
tidal action around the Pacific Ocean is very strong
many ocean trenches are located around the basin
a region of numerous tectonic plate boundaries and movements
16
The result of two oceanic plates diverging and magma wells up from the rift
mid-ocean ridge
folded mountains
island arc
unhappiness
17
Which type of plate boundaries involves a collision between two plates?
transform
hot spot
divergent
convergent
18
Which type of plate movement occurs where they are moving apart from each other?
a transform boundary
a convergent boundary
a divergent boundary
a strike-slip boundary
19
How do mid-ocean ridges form?
two tectonic plates moved toward each other
Earthquakes created a long ridge on the ocean floor.
two oceanic plates diverge and hot magma rises through rift
hot spots erupted along the ocean floor and created a ridge
20
Which feature usually forms when continental plates diverge on Earth's crust?
a fault-block mountain
a chain of volcanoes
an ocean trench
a rift valley
21
The result of two oceanic plates colliding
volcanic mountains
island arc
folded mountains
mid-ocean ridges
22
Which of the following best describes convection?
differences in the composition of magma causes movement
hot rock material flows upward, cools, then sinks
Energy from the magma touch the surrounding rock
Particles collide with each other transferring heat energy
