a fracture in the crust where earthquakes occur is called a:
and produces
waves
a
trench; subduction
b
boundary; sonar
c
gulch; electromagnetic
d
fault; seismic

Explanation:

A fault is a fracture in the Earth's crust. When there is movement along a fault, it causes earthquakes. Seismic waves are produced during an earthquake. A trench is related to subduction (a geological process at plate boundaries), a gulch is a landform (a narrow valley), and a boundary with sonar is not relevant to the description in the question.

Answer:

d. Fault; seismic
