1. How is a transform boundary different from a convergent boundary?
a.
b.
c.
d.
Plates move apart at transform boundaries, and toward each other at transverse boundaries
Plates move underneath one another at transform boundaries, and over one another at convergent boundaries
Plates move toward each other at convergent boundaries, and side-to-side at transform boundaries
Continental drift does not occur along convergent boundaries; it does occur at transform boundaries
2. At convergent boundaries, one plate is sometimes subducted below another. What is the best definition of “subduction?”
a. moving from side to side
b. pulling apart
c. pushing upward
d. sliding under
3. What is the term used to describe the area where thin oceanic plates spread apart, releasing magma and creating new
oceanic crust?
a. convergent boundary
b. normal fault line
c. mid-ocean ridge
d. subduction zone
4. Mid-ocean ridges are the most common type of __________________.
a. continental-continental collision
c. oceanic-oceanic collision
b. divergent boundary
d. subduction zone
5. Changes in density in the asthenopshere are caused by __________. (Section 3)
a. thermal energy
b. slab pull
c. ridge push
d. seismic waves
c. sea floor
d. asthenosphere
6. What can tectonic plates form at convergent boundaries?
a. mid-ocean ridges
b. mountains
7. Where would you be most likely to find a boundary between a continental and an oceanic plate?
a. in the center of the Pacific Ocean
c. off the west coast of North America
b. in the center of North America
d. At the boundary between Canada and the U.S.
8. What do scientists use the global positioning system for?
a. to measure tectonic plate motion
c. to make images of tectonic plates
b. to measure the Earth’s thickness
d. to locate fossils
9. Which of the following terms describes the area where the Himalaya Mountains formed?
a. divergent boundary
b. convergent boundary
c. subductive zone
d. transform boundary
10. How are fault-block Mountains different from folded mountains?
a.
b.
c.
d.
Fault-block mountains form where tectonic plates push together; folded mountains occur where plates pull apart
Fault-block mountains occur where two plates slide past; folded mountains occur where one slides underneath
Fault-block mountains occur where plates pull apart; folded mountains occur where plates push together
Fault-block mountains occur where one plate slides underneath; folded mountains occur where they slide past
11. If old mountains wear down over the course of millions of years, what is one of the primary reasons that mountains still
exist?
a.
b.
c.
d.
New mountains are created from the erosion of rock and soil.
New mountains are created through volcanic activity and lithospheric plate movement.
New mountains are created as a result of severe weather events, such as tornadoes and hurricanes.
New mountains are created as leaf litter builds up over millions of year.
12. The San Andres Fault is an example of a
a. reverse fault
b. normal fault
c. strike –slip fault
d. divergent plate boundary
13. What is an example of a fault block mountain?
a. The Grand Tetons
b. The Grand Canyon
c. The Himalayas
d. The Alps
14. Which mountain would you expect to find at a convergent boundary?
a. The Grand Tetons
b. The Alps
c. The Ring of Fire
d. The Grand Canyon
c. reverse fault
d. strike-slip fault
15. When tension pulls rocks apart, it creates a
a. normal fault
b. fold
16. The bending of rock layers due to stress in the Earth’s crust is known as
a. uplift
b. folding
c. faulting
d. subsidence
c. uplift
d. anticline
17. Which type of fold has an upward arching shape?
a. syncline
b. monocline
