The ​ (a)   are rockier, higher, and steeper. The other range has  ​ (b)   at the peaks. Both ranges follow the coast, but the ​ (c)   are considerably further inland and much further from the nearest plate boundary. The ​ (d)   show the effects of surface processes to a greater degree because they appear to be older and have undergone erosion for a longer period of time.

Place the statements under the corresponding mountain range.

Groups:

(a) Cascades

,

(b) Appalachians

• older

• less vegatation

• less soil and more rock

• more jagged

• steeper

• more rounded

• deeper soil

• younger

• less steep

• more vegetation

Near an active margin, mountains are likely to be ​ (a)   and ​ (b)   because they are continually forming. The mountains are likely to be relatively ​ (c)   the shore and ​ (d)   a plate boundary. 

• sharp
• steep
• close to
• far from
• rounded
• flat

What evidence suggests that volcanic activity in the Cascades is still ongoing?

• The erosion of volcanic islands

• Active volcanoes from the Juan de Fuca plate subduction

• The formation of new oceanic crust

• The disappearance of volcanoes over time

What marks the beginning of a passive continental margin?

• A divergent plate boundary

• A transform plate boundary

• A subduction zone

How does the continent change as new oceanic crust is added to the plate?

• The continent moves closer to the plate boundary

• The continent becomes more active

• The continent gets farther from the plate boundary

• The continent becomes more geologically unstable

What happens to the mountains or high regions on a passive continental margin over time?

• They grow taller due to volcanic activity

• They are rounded and worn down by destructive surface processes

• They become more volcanically active

• They are pushed deeper into the Earth's mantle
