Basalt

Basalt is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content, resulting in rapid lava flows that can spread over great areas before cooling and solidification. Flood basalt describes the

Advantages Disadvantages Of Weathering Of Rocks

Nov 20, 2009As weathering breaks down rock, it is ground and broken into smaller and smaller pieces. Some of these pieces turn into sediment, which forms sedimentary rock like limestone and sandstone. People use sedimentary stone for building and carving. The pieces of weathered rock are deposited, usually by a river. As more and more deposits build on top of older ones, the layers slowly compact
