Definitions:

Salt Glaciers

Masses of salt that flow similarly to ice glaciers, often forming in areas where large deposits of salt are subjected to intense pressure.

Weak Rock

Rock that is easily deformed or broken, usually due to its composition, weathering, or presence of numerous fractures.

Salt Deposits

Concentrations of salt left behind after the evaporation of saline water, typically found in arid environments or sedimentary basins.

Restricted Seaways

Narrow bodies of water that connect two larger bodies of water, often with limited water flow and unique ecological conditions.
