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) catastrophism.
B) isostasy.
C) accretion.
D) orogenesis.

Question

Quizplus · Accepted Answer

The process of the Hudson Bay rising and becoming dry is a result of isostasy, which refers to the rising or sinking of land due to adjustments in Earth's crust in response to changes in the weight distribution of land, water, and ice. As the glaciers melted, the weight of the ice was removed from the land, causing it to rebound and begin rising. This gradual rise will eventually cause the bay to become dry after it rises above sea level. Therefore, choice B, isostasy, is the best answer.
