[1] The displacement of rock layers can provide information on how and why Earth's lithosphere changes throughout geologic time.
Tectonic activity leads to vertical displacement when crust is rearranged during a seismic event.
Vertical displacement resulting from tectonic activity occurs at divergent and convergent plate boundaries.
This subduction induced the compression of the bounded western region of the North American plate which created the uplift of different layers of rock.
[6] Glacial isostatic rebound leads to sea level regression which can be measured using 14C dating to determine the age of sublittoral sediment in different regions along the seafloor.
