CORRELATION ACTIVITY

Correlation of cores from the Earth can be easy if you match them up unit by unit. Geologists would map an area and collect samples to confirm the units connected. For example, in the cores to the right, "a" has brown pebbles so you can correlate across the three cores.

In the following exercises you are looking at cores or outcrops and trying to see similarities. You look at similar rock types in one section and then connect it with the appropriate area. Coloring the units, one color helps to visually see the units easily. In the next exercise, follow the instructions for each activity.
