What Will Survive?
Archaeological remains include artifacts (portable) and features (non-portable) made and used by humans. Archaeologists use these objects to understand how ancient people lived. How well archaeological remains survive depends on the materials they were made of, the ways they were used, the manner in which they were discarded, and the environment in which they were deposited. Organic remains generally decay in a short time unless preserved in special conditions.

Try this activity from the Association of American State Geologists!
Water moves from Earth’s surface to the atmosphere and then returns to the surface. This process is nearly always depicted in water cycle diagrams by arrows drawn in a circular direction.
However, the actual path water may take in its cycle is far more complicated. In this activity, you will discover multiple cycles by acting as water molecules and traveling through parts of the overall water cycle. In the end, your water cycle will look nothing like the conceptual model but will represent a more realistic cycle.
