What did geologists discover from studying the aftermath of the 1964 Alaskan earthquake?
A) some parts of the coastline were uplifted and others subsided
B) changes in elevation were not systematic, occurring randomly over the area
C) there was no good explanation for large waves that resulted from the earthquake
D) fissuring of the ground and ice was limited to an area very near the epicenter
Coastline Uplifted
The rise of landmasses relative to the sea level, often caused by tectonic activities such as earthquakes or isostatic adjustments, leading to changes in coastal landscapes.
Subsided
The process by which an area of land sinks to a lower level than the surrounding land area, often due to natural geological processes or the extraction of underground resources.
1964 Alaskan Earthquake
A powerful seismic event that struck Southcentral Alaska on March 27, 1964, also known as the Great Alaskan Earthquake, the second most powerful earthquake ever recorded.

Final Answer :
A
Explanation :
The 1964 Alaskan earthquake, also known as the Great Alaskan Earthquake, was the most powerful earthquake recorded in North American history. Geologists studying its aftermath discovered that it caused significant geological changes, including the uplift and subsidence of different parts of the coastline. This phenomenon demonstrated the immense forces at play during such seismic events and helped to further understand the dynamics of the Earth's crust.
