Granite makes up a portion of the Earth's crust, and exists in virtually all land areas around the world. Granite forms the middle layer of the Earth's core, along with several other minerals and rocks. It forms the basis of the continental crust, and it also exists in seabeds.Know More
Granite belongs to the class of igneous rocks. It forms from two primary minerals, quartz and feldspar. It occurs in batholiths, or granite deposits, and appears naturally in mountain ranges and hills. Most granite comes in various shades of gray, although some rocks come in white and pink shades. Tiny specks of minerals along the outsides and in the core give granite a distinct appearance. Depending on location, granite sometimes has traces of other minerals, such as mica and hornblende.
Granite forms from the melting process of breaking down shale and sandstone. The resulting granite produced by this activity collects in deep deposits around the world. In North America, granite appears naturally in the Canadian Shield, forming a layer of bedrock. As a plentiful and cost-effective rock, it appears in many residences and commercial establishments. Granite makes a popular choice for home decorating, and serves as a decorative stone for commercial building improvements.Learn more about Geology
Iron can be found in the Earth's core, in the Earth's crust, in hemoglobin, in steel and in magnets. It is rare to find iron in its elemental form on Earth, but it has been found in igneous rocks in Russia.Full Answer >
Uranium can be found in low concentrations throughout the earth's crust and also dissolved in oceans, although it is found at higher concentrations in a number of places. The largest mines for uranium are in Canada, Australia, Niger, Kazakhstan, Russia and Namibia as of 2015.Full Answer >
Geodes are mostly found in deserts, volcanic ash beds and areas with limestone throughout the world. In the United States, common geode sites include Arizona, California, Iowa, Nevada and Utah. The most abundant geode sites in California are Riverside and Imperial counties.Full Answer >
Mountains are found on every continent in the world. Though there are some single-standing mountains, they are most often found in groups known as mountain ranges. Some mountains arise from volcanic eruptions, while others have been formed by the shifting of tectonic plates. Thus, mountains are commonly seen at the intersection of tectonic plates and in places where the Earth's crust is relatively thin.Full Answer >
