How hard is igneous rocks
http://geologyscience.com/rocks/igneous-rocks/kimberlite/ WebIgneous rocks are often very hard and durable, as the interlocking crystals give them strength and stability. Sedimentary rocks are often softer and less durable, as the materials that compose them are loosely compacted. Metamorphic rocks are harder and more durable than sedimentary rocks, but tend to be softer than igneous rocks. Formation
