This Sojourner rover image of the "Cabbage Patch" shows small rounded objects on the surface that are about 3-4 cm across. Several questions arise about the pebbles: 1. Why are they rounded? 2. Where did they come from? 3. What do they mean? Geologists use MULTIPLE WORKING HYPOTHESES when attempting to explain observations
