how did the ice ages affect sea levels?
a) they lowered sea levels and exposed land bridges.
b) they made oceans freeze permanently.
c) they had no effect on the oceans.
d) they caused sea levels to rise and flood continents.

Explanation:

During the Ice Ages, large amounts of water were locked up in glaciers. This led to a decrease in the volume of water in the oceans, resulting in lower sea levels. Lower sea levels could expose land bridges (such as the Bering Land Bridge which connected Asia and North America). Oceans did not freeze permanently (b is wrong), they had a significant effect (c is wrong), and sea levels lowered not rose (d is wrong).

Answer:

A. They lowered sea levels and exposed land bridges.
