D)underwater landslides.
E)uplift related to earthquake activity.

Question

Quizplus · Accepted Answer

Isostatic movement occurs when the weight on a land area changes, causing the land to rise or sink to reach equilibrium. In this case, the removal of a large glacier would cause the land to rise, resulting in isostatic movement of the coastline. Adding additional seawater would cause the coastline to flood, which is not the same as isostatic movement. Changes in seafloor spreading and underwater landslides could potentially cause changes in sea level, but they are not directly related to isostatic movement of a coastline. Uplift related to earthquake activity could cause isostatic movement, but it is not a choice in this question.
