Is magma hotter than lava? Is marble a metamorphic rock? Is mica a metamorphic rock? Which rock has more silica in it: granite or basalt? Is petrified wood a gem? Is halite a silicate? Is marble foliated? Do diamonds come from volcanoes?
If magma cools quickly, for example when basalt lava erupts from a volcano, then many crystals form very quickly, and the resulting rock is fine-grained, with crystals usually less than 1mm in size. If magma is trapped underground in an igneous intrusion, it cools slowly because it is insul...
Is granite an intrusive or extrusive igneous rock? Are sedimentary rocks intrusive or extrusive? Is basalt mafic or felsic? Is basalt an igneous rock? Is basalt a metamorphic rock? Is basalt a sedimentary rock? Is pumice an extrusive igneous rock? Is feldspar an igneous rock? What is intrusiv...
What stone is harder than granite? Both granite andquartziteare very hard, but on the Mohs scale of hardness (from 1 to 10, with 10 being hardest) quartzite has the slight edge. It measures around 7 whereas granite measures around 6 to 6.5. While quartzite is slightly harder than granite,...
Granite is the signature rock of the continents. More than that, granite is the signature rock of the planet Earth itself. The other rocky planets—Mercury, Venus, and Mars—are covered withbasalt, as is the ocean floor of Earth. But only Earth has this beautiful and interesting rock type...
Is granite a metamorphic rock? Is basalt an igneous rock? Is gneiss a igneous rock? Is marble a igneous rock? Is sandstone a igneous rock? Is quartz an igneous rock? Is feldspar an igneous rock? Is shale an igneous rock? Is slate an igneous rock? Is a diamond an igneous rock? Is ...
relatively thin wooden handle for gripping. Metal used for the heads of bush hammers is often tungsten carbide or steel. The hand-powered version is most frequently used in art, on softer sculpting stones like limestone and marble. Harder stones like granite can be bush-hammered by more powerfu...
Is quartzite harder than granite? What is gneiss made of? Is marble a form of limestone? What is basalt rock? What is the hardness of sandstone? What do different rock textures of metamorphic rock reflect? What is the difference between magma and lava? What is migmatite gneiss? Is granite...
Mafic rocksinclude basalt, its intrusive equivalent of gabbro, and a variety of less common rock types with higher or lower contents of Na and K. Andesite and its intrusive equivalent, diorite, with slightly higher silica content, are intermediate between mafic and felsic. ...
