Question

question 1
which pair of boundaries in your model are most likely to create new land over time?
convergent (c-c) and transform
transform and convergent (o-c)
divergent and convergant (o-c)
question 2
2 points
if a real - world transform fault suddenly locked in place for decades, which event would
you predict when it finally moved?
a large earthquake
a deep trench forming
a volcanic eruption

Explanation:

Question 1

To determine which boundaries create new land, we analyze plate boundary types:

• Divergent boundaries: Plates move apart, allowing magma to rise and form new crust (e.g., mid - ocean ridges, rift valleys that can develop into new land).
• Convergent (o - c, ocean - continental) boundaries: Oceanic plate subducts, but volcanic arcs (like island arcs) can form new land from volcanic activity.
• Convergent (c - c, continental - continental) boundaries: Plates collide, causing mountain - building (no new land creation, just deformation).
• Transform boundaries: Plates slide past, no new land creation (just faulting).

So Divergent (creates new crust) and Convergent (o - c, volcanic new land) are the pair that creates new land.

Transform faults involve plates sliding past each other. When a transform fault is locked, stress builds up as the plates try to move but can't. When the fault finally moves, the accumulated stress is released suddenly, which causes a large earthquake.

• A deep trench forms at convergent (o - c) boundaries, not transform.
• Volcanic eruptions are associated with divergent or convergent (o - c) boundaries, not transform faults.

Answer:

Divergent and Convergant (o - c)
