Question

1 a student is developing a model of two tectonic plate boundaries.
model of two plate boundaries
mantle
mountain range
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 arrows show plates moving apart, which is a divergent plate boundary, where new crust forms as magma rises and solidifies.
• Label Y: The arrows show one plate subducting under another, forming a convergent boundary, where crust is recycled into the mantle.
• Option A correctly identifies the boundaries and matches the process (new crust formation at X) to the correct location. Options B, C, D mix up boundary types or link incorrect processes to the locations.

Answer:

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