Final answer:
Geologic, paleontological, and chemical evidence are the main types of evidence that indicate ice ages.
Step-by-step explanation:
One of the main types of evidence that indicate ice ages is geologic evidence. Geologic evidence includes features that were formed by glaciers, such as moraines, drumlins, and erratics. Another type of evidence is paleontological evidence, which includes the presence of fossils of ice age plants and animals in different regions. Lastly, chemical evidence is also important in studying ice ages, such as the analysis of ice cores to determine the composition of gases in the atmosphere during different time periods.
