What are the most common felsic minerals?
Regional SpecificsThe most common felsic rock is granite. Common felsic minerals include quartz, muscovite, orthoclase, and the sodium-rich plagioclase feldspars (albite-rich). What are common felsic minerals? Common felsic minerals include quartz, muscovite mica, and the orthoclase feldspars. The most common felsic rock is granite, which represents the purified end product of the earth’s internal differentiation process.

What are the three main causes of plate tectonics?
Regional SpecificsWhat are three causes of plate movement? Mantle dynamics, gravity, and Earth’s rotation taken altogether causes the plate movements. However, convectional currents are the general thought for the motion. What is the main cause of plate tectonics on Earth? The force that causes most of the plate movement is thermal convection, where heat from the

What are the common rock forming minerals?
Regional SpecificsThe rock-forming minerals are: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals occurring within a rock in small quantities are referred to as “accessory minerals”. Which is the most common rock forming mineral? silicates The most common rock-forming minerals are silicates (see Vol. IVA: Mineral Classes: Silicates), but they also include oxides, hydroxides, sulfides,

What is the use of siltstone?
Regional SpecificsSiltstone Uses It is rarely mining for use as a construction material or manufacturing feedstock. The pore spaces of siltstone serve as good aquifer. It is rarely porous enough or extensive enough to serve as an oil or gas reservoir. Its main use is as a low-quality fill when better materials are not locally available.

When and how do earthquakes occur?
Regional SpecificsThe tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. When and where do earthquakes usually occur?

What is a plate science?
Regional SpecificsWhat is a plates in science? A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. What is
