For millions of years, large amounts of glacial ice formed on Earth, covering huge areas
land. It then melted, or receded. When large amounts of glacial ice formed, large
amounts of water froze. When the glacial ice melted, it released water into the oceans.
Based on this evidence, which claim describes the effect glaciers had on the formation
of Florida?
a. Florida's coastlines were eroded only during cold periods.
b. Florida's coastlines were eroded only during warm periods.
c. Different parts of Florida's coastlines were eroded during warm and cold periods.

d. Florida's mountains were eroded only during warm periods.
