Why Did the Ice Age Happen?

Answer

Ice Age happened because of the long-term reduction in the temperature of the Earth's surface and atmosphere. It resulted in the presence or expansion of continental ice sheets, polar ice sheets and alpine glaciers. A general reduction in the amount of carbon dioxide in the atmosphere may contribute to the development of ice ages.

There are many theories as to why there was a period of time called the ice age. There are at least five known ice ages in Earth's history. Generally, atmospheric conditions, changes in the Earth's orbit, wind and ocean currents and the movement of tectonic plates are some of the factors of an ice age.
