Lesson Plate Tectonics

Question 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

Question 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 mountains.
• C: As two oceanic plate 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.

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 (edge) 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

A hot spot can produce

• A: a chain of islands
• B: a mid-ocean ridge
• C: a trench
• D: a tectonic plate
