Question

1 a student is developing a model of two tectonic plate boundaries.
model of two plate boundaries
the model is incomplete. which set of information identifies the labels the student should use to complete the model and describes a process shown in the model?
a
label x: divergent plate boundary
label y: convergent plate boundary
description: new crust is being formed at location x.
b
label x: convergent plate boundary
label y: divergent plate boundary
description: new crust is being formed at location y.
c
label x: divergent plate boundary
label y: convergent plate boundary
description: crust is being recycled by earths mantle at location x.
d
label x: convergent plate boundary
label y: divergent plate boundary
description: crust is being recycled by earths mantle at location y.

Explanation:

• Label X: The plates are moving away from each other, which is a divergent plate boundary, where new crust forms as magma rises.
• Label Y: One plate is subducting under the other, which is a convergent plate boundary, where crust is recycled into the mantle.
• Option A correctly identifies the boundary types and the process at X (new crust formation).

Answer:

A. Label X: divergent plate boundary
Label Y: convergent plate boundary
Description: New crust is being formed at location X.
