Technological methods used to prove that plate tectonics occur include:
a.
earthquake tracking and satellite images
c.
ocean floor mapping and satellite images
b.
volcanic activity tracking and satellite images
d.
ocean floor mapping and earthquake tracking

The correct answer is D. ocean floor mapping and earthquake tracking

Tracking earthquakes is helpful because it shows where it came from and what caused it, as well as how it affected the environment, while ocean floor mapping is useful because it shows how the bottom of the sea changed over time which happens due to tectonic activity.
