Periods of long term colder temperatures and expansion of polar ice sheets and glaciers is called a. An lce age b. Winter c. Glaciation d. Seasons

Ice ages are fascinating! They represent significant climatic shifts over geological time, marked by long periods of cooler global temperatures. During an ice age, ice sheets expand from the polar regions, covering vast areas of continents, profoundly influencing Earth's environment and ecosystems. In terms of real-world impacts, ice ages have shaped our landscapes—think the Great Lakes, carved out by glacial movements! They also play a crucial role in understanding climate change, as studying these past events helps scientists predict future climatic trends and their potential consequences for our planet.
