An ice age is a period in which large areas of Earth are covered in ice. Which statement best explains how Earth temperature would be affected

An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years.

Explanation:These global cooling periods begin when a drop in temperature prevents snow from fully melting in some areas. The bottom layer turns to ice, which becomes a glacier as the weight of accumulated snow causes it to slowly move forward. A cyclical pattern emerges in which the snow and ice traps the Earth’s moisture, fueling the growth of these ice sheets as the sea levels simultaneously drop.
