1. What is the scientific discipline?A subfield of geology focused on the Quaternary Period
2. What is the interdisciplinary connections?Strong links to paleoclimatology, archaeology, paleontology, and environmental science
3. Why do scientists call the Quaternary Period the "Ice Age"?Because during this time, large ice sheets repeatedly covered and retreated from the continents.
4. How do scientists learn about past climates?They examine rocks, sediments, fossils, and other natural clues, using special dating methods to find out when they were formed.

Quaternary Period: The most recent geological period, characterized by significant climate fluctuations, including repeated ice ages.
Pleistocene Epoch: The earlier epoch of the Quaternary, often referred to as the 'Great Ice Age,' marked by extensive glaciation.
Holocene Epoch: The current epoch, beginning approximately 11,700 years ago, characterized by warmer interglacial conditions.
Paleoclimate Proxies: Natural archives (like ice cores or sediment layers) that preserve evidence of past climate conditions.
