Question

plate tectonics anchor chart
landforms at each plate boundary
convergent boundaries
1 mountains
2 volcanoes
3 ocean trenches
divergent boundaries
1 volcano
2 continental rift
transform
1 fault

Explanation:

The problem is about plate tectonics and landforms at plate boundaries, which falls under the subfield of Geography (Natural Science). The anchor chart lists landforms for convergent, divergent, and transform boundaries. For example, convergent boundaries have mountains, volcanoes, ocean trenches; divergent have volcano, continental rift; transform has faults. This is a key concept in Geography (specifically physical geography) related to plate tectonics.

Answer:

The subfield is Geography (under Natural Science).
