A hypothesis is a causal explanation that can be tested, either by conducting additional investigations or by examining data that already exist. Another explanation is that the buried tank is not the source of the contamination. Instead, the source is somewhere else, and contamination flowed into the area. We develop predictions for each explanation. A prediction for the explanation in number 4 might be that the tank has some kind of leak and should be surrounded by gasoline.
Also, if the explanation in number 4 is true, the type of gasoline in the tank should be the same as in the groundwater. Next, we plan some way to test the predictions, such as by inspecting the tank or analyzing the gasoline in the tank and groundwater.
To study this problem, an early step is to compile all the necessary data. This might include maps showing the location of water wells, locations of gas stations and other possible sources of gasoline, and the direction of groundwater flow. In our case, investigation discovered no holes in the tank or any gasoline in the soil around the tank.
Records show that the tank held leaded gasoline, but gasoline in the groundwater is unleaded. We compare the results of any investigation with the predictions to determine which possible explanation is most consistent with the new data.
Data collected during the investigation support the conclusion that the buried tank is not the source of contamination. Any explanation that is inconsistent with data is probably incorrect, so we pursue other explanations. In this example, a nearby underground pipeline may be the source of the gasoline.

Geographers use GIS to find relationships and trends in geographic data. GIS allows them to present data visually as maps, reports, and charts. For example, a geographer can overlay aerial or satellite images with GIS data, such as population density in a given region, and create computerized maps.
They then use the results to advise governments, businesses, and the general public on a variety of issues, such as marketing strategies; planning homes, roads, and landfills; or disaster responses. Geographers have distinct personalities.
They are curious, methodical, rational, analytical, and logical.
