Assateague National Seashore is shifting location primarily due to which climate change effect?

The correct choice is sea level rise, which is a significant consequence of climate change. As global temperatures increase due to elevated greenhouse gas emissions, polar ice caps and glaciers are melting, leading to a direct rise in sea levels. This rising water encroaches on coastal areas such as Assateague National Seashore, causing shifts in the land and altering the natural landscape.

The impact of sea level rise is multifaceted. It can lead to increased coastal erosion, flooding of low-lying areas, and changes in sediment deposition patterns, which can affect the local ecosystems and wildlife. The gradual change of the coastline as a result of rising seas contributes to the movement of habitats and can affect biodiversity in these regions.

Other options like melting glaciers, ocean acidification, and increased storm frequency, while related to climate change, do not primarily contribute to the shift in location of Assateague National Seashore. Melting glaciers predominantly affects freshwater availability and contributes to sea level rise rather than directly shifting coastal ecosystems. Ocean acidification impacts marine life and ecosystems, particularly those relying on calcium carbonate, but does not involve geographic shifts of land. Increased storm frequency can lead to localized erosion and changes, but without the overarching impact of continuous land inundation that sea level
