Which influence decreases sandstone arch strength due to enhanced weathering near its base?

💡 Explanation

An increase in sandstone pore water enhances salt weathering. Capillary action draws groundwater upwards, because dissolved salts precipitate during evaporation which intensifies physical disintegration; therefore strength decreases specifically at the base, rather than changes in reflective heating.
