Sinkholes form due to dissolution of ______Group of answer choicesquartzlimestonesandstonegranite

Breakdown the Problem

1. Identify the types of rocks mentioned in the choices: quartz, limestone, sandstone, and granite.
2. Understand the process of sinkhole formation.
3. Determine which type of rock is most susceptible to dissolution.

Relevant Concepts

1. Sinkholes typically form in areas where water can infiltrate into the ground and dissolve certain types of bedrock.
2. The most common rock associated with sinkhole formation is limestone, which is susceptible to chemical weathering and dissolution by carbonic acid found in water.

Analysis and Detail

1. Quartz: Very hard and resistant to weathering; does not dissolve significantly in water.
2. Limestone: Composed primarily of calcium carbonate, it readily dissolves in slightly acidic water, leading to the formation of voids and potential sinkholes.
3. Sandstone: Composed of sand-sized particles, it is more resistant but can erode over time; however, it is less prone to sinkhole formation compared to limestone.
4. Granite: A hard igneous rock that weathers slowly and does not dissolve easily in water.

Verify and Summarize

Limestone is well-known for its ability to dissolve and create underground voids, which are precursors to sinkholes. The other rock types either do not dissolve easily or are not typically associated with sinkhole formation.

Final Answer

Sinkholes form due to the dissolution of limestone.
