It is contradictory...
For every % of erosion that occurs by another method then their proposed "precipitation induced weathering" it lessens the validity of their ancient Sphinx claim... you cannot have 50% dissolution and 50% salt exfoliation and the Sphinx 10,000 years old... dissolution of calcite by rainwater has to be as close to 100% as possible, all other weathering mechanisms must play no significant role in the erosion of the Sphinx.
