The instrument used to measure and record earthquake waves.
a) Richter scale
b) seismograph
c) barograph
d) spectograph
The movement of tectonic plates is caused by....
a) heat in the inner core
b) radiation from the sun
c) strong global winds
d) convection currents in the mantle
What feature do volcanoes form as tectonic plates move apart?
a) hot spot
b) hydrothermal vent
c) subduction zone
d) mid-ocean ridge
Which of the observations best supports the theory of plate tectonics?
a) Fossils of many different kinds of organisms have been found at the same location.
b) Fossils of the same species of organism have been found on opposite sides of the same ocean.
c) Fossils show which direction the plates moved
d) Fossils were more likely to form during early periods because the organisms were much larger than today.
A long term benefit of volcanoes
a) More oxygen in the atmosphere
b) warmer temperatures
c) lower sea levels
d) fertile soil
Molten rock that has erupted out of a volcano is known as
a) magma
b) pyroclastic flow
c) igneous rock
d) lava
When two tectonic plates collide.
a) divergent boundary
b) convergent boundary
c) transform boundary
d) mid-continent boundary
Where are most volcanoes and earthquakes located?
a) In the middle of continents
b) Along the edges of tectonic plates
c) Along the equator
d) Near the North and South poles
On average, how far do tectonic plates move in a year?
a) 5 meters
b) 4 feet
c) 5 centimeters
d) 100 inches
Which of the following best explains the difference between continental drift and plate tectonics?
a) Continental drift describes the motion of Earth's continents; plate tectonics describes the motion of the ocean crust
b) Continental drift is supported by observations of coastline shape; plate tectonics based on fossil evidence alone.
c) Plate tectonics was Wergner's theory describing how the plates formed and moved across oceans.
d) Continental drift was Wegener's hypothesis that continents were once a supercontinent; plate tectonics explains cont. drift
The energy released by an earthquake travels in the form of .....
a) gravity waves
b) radiation waves
c) seismic waves
d) cosmic waves
Tectonic plates slide horizontally past each other at which type of boundary?
a) transform
b) divergent
c) fault block
d) convergent
The movement of tectonic plates can cause....
a) glaciers
b) earthquakes
c) impact craters
d) fossil beds
What type of wave could be caused by an underwater earthquake?
a) typhoon
b) hurricane
c) tornado
d) tsunami
Most earthquakes are caused by....
a) currents in the Earth's inner core
b) the impact of large meteorites
c) coal mines and oil well drilling
d) the movement of tectonic plates
A student argues that the theory of plate tectonics is false because we do not feel the plates move beneath our feet. What is wrong with this argument?
a) The plates are all moving at the same speed relative to each other.
b) On average, plates move only a few centimeters per year
c) Tectonic plates are located in Earth's aesthenosphere, too far beneath the planets surface for us to feel them moving.
d) The student is correct; plate tectonics is no longer considered a valid theory.
The Ring of Fire is a long string of volcanoes located around the edge of
a) Pacific Ocean

a) U shaped valleys
b) mid ocean rift
c) mountains
d) canyons
