- 1. Multiple Choice
Which of these describes a cause of lithospheric plate movement across the surface of Earth?
The plates are driven by bubbles from the boiling liquid of the asthenosphere.
The plates float on dense liquid material of the asthenosphere and are moved by tidal forces.
The plates are driven across the surface by convection currents within the plastic rock of the asthenosphere.
The plates move because they are attached to the solid rock of the asthenosphere and move with that rock.
- 2. Multiple Choice
Two plates composed of rock of similar density meet along a convergent boundary. Which statement describes what will happen where the two plates meet?
The plates will rub against each other, causing shearing and creating fault lines in the interior of the plates.
The plates will collide with neither plate subducting, causing the crust to pile up and form a mountain range.
The plates will collide, and the compression will heat the plates, causing some of the plates to melt and form volcanic mountains.
The plates will rub against each other, causing one plate to subduct underneath the other plate and forming a deep trench along the boundary
- 3. Multiple Choice
Heat from deep in Earth’s interior is transferred to its crust by which of the following?
conduction in the ocean
convection in the mantle
radiation in the solid core
evaporation at mid ocean ridges
- 4. Multiple Choice
Seafloor spreading provides evidence of which of the following Earth processes?
erosion of coastlines
weathering of mountains
movement of crustal plates
formation of sedimentary rocks
- 5. Multiple Choice
The following diagram shows the motion of two plates. Which of these explains the feature that can form at the boundary of these two plates?
A broad canyon-like valley because the two colliding plates act like a plow, digging out any soil in the plates’ paths.
Volcanic mountain range because one oceanic plate melts underneath the continental plate, forming composite volcanoes on the continent
Island arc because one oceanic plate melts underneath the continental plate, forming volcanic mountains that eventually become islands
Folded mountain range because the two colliding plates have equal composition and density, causing both to fold and form wide, thick mountains
- 6. Multiple Choice
Which of these MOST LIKELY forms when large
sections of Earth’s crust collide with each other?
Reefs
Gullies
Craters
Mountains
- 7. Multiple Choice
Which of these describes a divergent boundary?
Two continental plates moving away from each other, forming a rift valley
Two oceanic plates rubbing against each other, forming a midocean ridge
Two continental plates colliding, forming a mountain range
Two oceanic plates colliding, forming a volcanic arc
- 8. Multiple Choice
The San Andreas Fault is a transform fault that is located at the border of the North American Plate and the
Pacific Plate. What would MOST LIKELY form along this fault if it were a convergent fault rather than a transform fault?
Rivers
Mountains
Rift valleys
Island chains
- 9. Multiple Choice
What process is forming high nonvolcanic mountains at location D on the map?
One tectonic plate is splitting apart into two plates.
Two tectonic plates are colliding and pushing together.
One tectonic plate is sliding past another tectonic plate.
Two tectonic plates are colliding and one is sliding under the other.
- 10. Multiple Choice
A line of volcanoes occurs along the western coast of South America, near location O. Based on the information about plate movement on the map, which process explains the formation of these volcanoes?
A subducting of one plate under the other causing melting of the lower plate
sliding of one plate sideways past another resulting in friction and melting
melting of crust because of plate movement over a “hot spot”
rifting of a plate with lava filling in the resulting valley
- 11. Multiple Choice
Which statement is explains how ancient coral reef fossils can be found high in the mountains far from any sea?
huge tidal wave pushed marine life up into the mountains.
Prehistoric man carried fish into the mountains from the sea
Fish were thrown into the mountains by a tremendous volcanic explosion.
Land that was uplifted to form the mountains was once covered by the sea
- 12. Multiple Choice

earthquakes
mountain chains
rift valleys
volcanic formations
- 13. Multiple Choice

tectonic plates pull apart
tectonic plates slide past one another
tectonic plate goes underneath another plate
- 15. Multiple Choice
