Final answer:
Evaporation leads to the formation of thick rock salt deposits in bedrock at some locations in New York State.
Step-by-step explanation:
The process that led to the formation of thick rock salt deposits found in the bedrock at some location in New York State is evaporation. Evaporation occurs when water evaporates from a body of water or a solution, leaving behind the dissolved minerals, such as salt, to form sedimentary deposits. In the case of rock salt deposits, ancient bodies of water such as seas or lakes evaporated over time, leaving behind the salt deposits.
