Table 2. Testing Explanations for the Origin of Upheaval Dome

For each of the three possible explanations for the origin of Upheaval Dome, (1) draw a sketch that illustrates the type of rocks you might find at depth, (2) list a prediction for each explanation, and explain how you might test that prediction, and (3) list additional information you might need to investigate its origin.

Explanation 1: Dome warped by rising mass of salt

Explanation 2: Dome is the result of rising magma

Explanation 3: Dome formed by meteoroid impact
