Final answer:
The statement is true; sea-level rise in Scandinavia and the mid-Atlantic region of the U.S. is partly due to isostatic rebound, as well as other factors influencing regional sea levels.
Step-by-step explanation:
The statement that sea-level rise in Scandinavia and the mid-Atlantic region of the U.S. results partly from isostatic rebound is true. Isostatic rebound refers to the rise of land masses that were depressed by the huge weight of ice sheets during the last ice age. This process is still occurring today and contributes to changes in sea level in some parts of the world. In Scandinavia, the land is rising, making the relative sea level appear to fall. However, in the mid-Atlantic region of the U.S., the process of isostatic rebound contributes to sea-level rise in a different way as land previously uplifted by the presence of a glaciation is now subsiding. This is different from the eustatic sea-level rise, which is a worldwide change in sea level due to variations in the volume of water in the oceans, often as a result of melting ice sheets and the thermal expansion of seawater as it warms.
Warming temperatures lead to sea level rise by expanding ocean water, melting glaciers, and ice caps, and causing portions of Greenland and Antarctica ice sheets to melt or flow into the ocean. Various factors, such as thermal expansion, the melting of ice caps and glaciers, and changes in ice sheets contribute to sea level rise. Relative sea level rise will vary for different regions due to regional and local factors, including geological forces like subsidence or uplift, and effects such as currents, winds, salinity, and water temperatures.
