WebApr 25, 2024 · An ice age is a moment in time when global temperatures can reach drastically cold levels. The decreased temperatures prevent snow from melting which creates a layer of ice under all of the accumulating snow. This phenomenon causes the whole ice mass to move; in other words, a glacier is created. WebThere are several natural forces that together lead to an ice age on Earth. The answer lies in how the orbit of the Earth around the sun changes. The average temperature on Earth depends on the Earth’s distance from the sun. If the Earth were closer to the sun, it would be hotter; if the Earth were further away from the sun, it would be colder
