Is a igneous rock waterproof

Igneous rocks are generally considered to be more resistant to water than sedimentary rocks due to their dense and crystalline structure. However, they are not completely waterproof; water can still penetrate through microscopic pores and fractures. The degree of water resistance can vary depending on the specific type of igneous rock and its mineral composition. Overall, while they are relatively durable, they are not entirely impervious to water.
