Answer the following question given this paragraph: 

Many Earth scientists collect data in the field, called field work . The data may be from observations or measurements. The scientists may create a geological map of the area. They might write detailed descriptions of the rocks and their relationships. They may collect samples to analyze in the lab. They may do a combination of all of these! Earth science laboratories contain high-tech equipment. That equipment can reveal the chemistry or age of a rock sample. Geologists do field work to look for resources. They may study a region for environmental cleanup. There are many other reasons for going in the field. One common reason is just to understand the region better.
