Question

Quizplus · Accepted Answer

Shale is a fine-grained sedimentary rock that has low permeability, which makes it an ideal cap rock for oil and natural gas deposits. Due to its low permeability, it acts as a seal, preventing the oil and gas from escaping to the surface. Sandstone, limestone, and conglomerate, on the other hand, are more permeable and would allow the oil and gas to leak out.
