Question

read the passage and look at the picture.
the japan trench is a deep - sea trench east of the islands of japan. the trench formed as the pacific plate subducted, or sank, below the okhotsk plate. the two plates continue to move toward each other. this movement can cause devastating earthquakes in japan, such as a magnitude 9.0 earthquake that occurred on march 11, 2011.
complete the sentence.
the japan trench formed at a ______ boundary.
convergent
divergent
transform

Explanation:

The passage states the Pacific Plate subducted (sank) below the Okhotsk Plate to form the Japan Trench. This type of plate movement, where plates move toward each other and one subducts under the other, defines a convergent plate boundary. Divergent boundaries involve plates moving apart, and transform boundaries involve plates sliding past each other, which do not match the described formation.

Answer:

convergent
