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:

Explanation 3:
Dome warped by rising mass of salt
Dome is the result of rising magma
Dome formed by meteoroid impact
