Drilling is the only way to be sure that oil and gas fields exist and exactly what is present in the formation. Core samples reveal the physical and chemical nature of the rock. In this activity, you will create a model formation and “drill” for samples.
How much of a danger does severe weather pose for the area where you live? You can compute the answer yourself in this exercise.
How do geologists understand the Earth’s history? In part, they measure the age of rocks and other natural materials by dating techniques. They can date rocks by gauging the amount of decay of radioactive elements. You can simulate the dating process with popcorn.
This activity enables students to estimate and calculate scales of distance and length as used by ocean drilling scientists.
Geologic maps show the locations of various kinds of rocks at the surface. In places where rivers have eroded the surface, deeper layers become exposed. The opposite occurs when lake levels rise; rocks along the shore are covered by water. Geologic clues in each layer can be used to tell a story of Earth’s history. Differences between one layer and the next reveal changes in the Earth system.
Learn how soil scientists observe and record data and how that information is useful to farmers, builders, and others in order to use the land appropriately.
