If the chips in your driveway formed over time, skim coating and sealing the surface is a simple cosmetic solution. For a new driveway, excessive chipping can indicate that the slab itself is weak. Causes for weak concrete include drying out the surface too quickly or low quality concrete.
Igneous rocks are rocks that have formed out of magma (molten rock). The two types of igneous rocks most common on Earth are called granite and basalt. Granite is a rock that typically looks pink and white with black specks.Basalt generally just looks black.o summarize, the two types of igneous rocks by chemical composition are felsic and mafic. Granite-typically composed of orthoclase, hornblende, biotite, and quartz-is a felsic rock type. Basalt is mostly olivine, augite, and calcium-rich plagioclase, therefore mafic. slide 3 of 6.
Basalt vs Granite. Earth is made up of three kinds of rocks namely igneous rocks, sedimentary rocks, and metamorphic rocks. Basalt and granite are two types of igneous rocks. All rocks of igneous origin are made up of magma or molten earth that finds its way up to the surface of the earth from fissures and cracks underneath the surface of earth. The molten rocks that come out in the form of lava, upon cooling takes shape of igneous rocks.
