Glaciers that once covered the Hudson Bay area melted 8,000 years ago. As a result of this, the bay is gradually rising. In another 10,000 years or so, it will have risen above sea level and become dry. This process can best be considered an example of:
a. isostatic rebound.
b. accretion.
c. orogenesis.
d. catastrophism.
e. ice regulation.
