7. Explain how a hot spot creates a chain of volcanoes.
Follow-up Question: Why are some volcanoes created by a hot spot no longer active?
Lesson Review:
1. Which landform is most likely to form where two oceanic plates push together?
a. Folded mountain
b. Mid-ocean ridge
c. River valley d. Volcanic island
Follow-up question: Which is likely to form where two oceanic plates pull apart? _____________
2. A chain of mountains is located along the western coast of a continent next to a plate boundary. Which
sentence describes how the mountains most likely formed?
a. As a continental plate and an oceanic plate slid past each other, a fault formed, and mountains
were produced by earthquake movement.
b. As a continental plate and an oceanic plate collided, part of the oceanic plate was pushed under
the continental plate, and volcanoes erupted, forming the mountains.
c. As two oceanic plates collided, one of the oceanic plates was pushed under the other plate, which
rose to the surface, forming folded mountains.
d. As two oceanic plates moved apart, new seafloor was produced, forming a ridge.
Follow-up question: Which answer could not have taken place at the coast of a continent? _____
3. Where does sea-floor spreading occur?
a. Where two oceanic plates collide
b. Where an oceanic plate and a continental plate collide
c. Where two oceanic plates move apart
d. Where two continental plates move apart
4. At which location are earthquakes least likely to occur?
a. At a boundary where plates push together
b. At a boundary where plates move apart
c. At a boundary where plates slide by each other
d. In the middle of a plate
Follow-up question: Why?
5. A hot spot can produce
a. A chain of islands
b. a mid-ocean ridge
c. a trench
d. a tectonic plate
Follow-up question: Where do hot spots typically form? __________________________________
