What is another word for glaciations?
Pronunciation: [ɡlˌe͡ɪsɪˈe͡ɪʃənz] (IPA) 
Glaciations, also known as ice ages, have occurred throughout Earth's history. They are periods of time where the Earth's climate cools and large ice sheets start to form on the planet's surface. Synonyms for the term glaciations include "glacial period," "ice age," "frost epoch," and "cold spell." The geological evidence of glaciations can be seen in various features such as moraines, valleys, and erratic boulders. The last major glaciation period occurred roughly 10,000 years ago and lasted for about 100,000 years. Today, the Earth is in an interglacial period, and there are ongoing debates about whether another glaciation period is imminent or how humans may be affecting the Earth's climate.
