How Natural Gas Forms
In this activity, you’ll make a model of how natural gas might be formed from decaying organic material.
Rain and Soil
When it rains, much of the water drains directly into the ground. But why?
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.
