Where can granite be found?
GeologyAsked by: Carrie Montoya Granite is mined worldwide but the most exotic colours are obtained from granite deposits in China, India, Brazil, Finland and South Africa. Granite mining is a capital and labour-intensive process. Blocks of granite are extracted from deposits by cutting or blasting procedures. Where in the world can granite be found? Traditionally,

What are igneous rocks How are they formed?
GeologyAsked by: Shane Stacks Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. What are igneous rocks How are they formed Class 7? Igneous rocks are defined as types

Can San Andreas happen?
GeologyAsked by: Gregory Gonzalez No. Seismologist Lucy Jones says that the level of destruction is over-the-top (The Hollywood Reporter). New buildings are designed to be able to withstand large scale quakes, at least to enough of a degree that people would be able to escape. When San Andreas will happen? Narrator: On average, the San

What part of Puerto Rico did the earthquake hit?
GeologyAsked by: Kelly Brinson The largest earthquake in Puerto Rico: today: 2.5 in Tallaboa, Penuelas, Puerto Rico. Where was the earthquake damage in Puerto Rico? The hardest hit towns were Guánica, Utuado, Guayanilla, Peñuelas, Ponce and Yauco. The governor authorized $2 million in assistance to support these towns. In the town of Guayanilla, a picturesque

What is limestone composed of?
GeologyAsked by: Mike Mohamed Limestone is a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg(CO3)2). What is most limestone formed from? Most limestone layers formed from marine sediment deposited on sea floors, although some formed

What is the continental crust made of?
GeologyAsked by: Susan Brown Continental Crust Continental crust is mostly composed of different types of granites. Geologists often refer to the rocks of the continental crust as “sial.” Sial stands for silicate and aluminum, the most abundant minerals in continental crust. What is a continental crust? continental crust, the outermost layer of Earth’s lithosphere that

Which minerals contain the two most abundant elements by mass in Earth’s crust?
GeologyAsked by: Stephanie Green Silicates. Silicate minerals contain silicon (Sisilicon (SiPhosphasilenes or silylidenephosphanes are a class of compounds with silicon-phosphorus double bonds. Since the electronegativity of phosphorus (2.1) is higher than that of silicon (1.9), the “Si=P” moiety of phosphasilene is polarized. Which minerals contain the two most abundant element by mass in earths crust?

What would you be most likely to find at a transform boundary?
GeologyAsked by: Giovanni Drollinger This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults. A well-known example of a transform plate boundary is the San Andreas Fault in California.

What kind of forces act on the crust at divergent boundaries?
GeologyAsked by: Dale Drew Answer and Explanation: Tensional forces are present at divergent boundaries. The convection currents in the upper mantle push the tectonic plates in opposite directions at divergent boundaries. Divergent plate boundaries are also known as rift zones. What is the force called that pushes apart the divergent zone? Ridge push (also known

Do the Galapagos Islands move?
GeologyAsked by: Maggie Thomas Since the Galápagos Islands are moving with the Nazca plate and the hot spot remains stationary, the islands form and slowly drift away from the hot spot, at about 5cm per year, allowing more volcanoes and islands to be formed. How often do the Galapagos Islands move? The islands sit on
