Which mineral can be found in the rocks Phylite sandstone and granite?
GeologyWhich mineral can be found in rocks phyllite sandstone and granite? Quartz is one of the most common minerals in the Earth’s crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic
How do you classify rocks igneous metamorphic and sedimentary?
GeologyIgneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground. How do you classify rocks? CLASSIFICATION The classification of rocks is based on two criteria, TEXTURE
Where should a two story house be during an earthquake?
GeologyTwo-story apartment buildings may be safe if they were built to current safety standards, or they may be dangerous if they are located over a “soft story” such as a parking area and have not been retrofitted. The best way to endure an earthquake safely is to be prepared and follow earthquake safety tips. What
What is the rate of continental drift?
GeologyThe two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. What is the speed of continental plates? They move at a rate of one to two inches (three to five centimeters) per year. Is continental drift speeding up? The researchers found the frequency with which
What is a slab of volcanic rock formed when magma is forced up and flows out as lava?
GeologyWhat is a slab of volcanic rock formed when magma is forced up and flows out as lava called? A B SILL A slab of volcanic rock formed when magma squeezes between layers of rock. BATHOLITH A mass of rock formed when a large body of magma cooled inside the crust. What is molten rock
Is Azomite glacial rock dust?
GeologyAzomite is very different from the few glacial rock dust products on the market. AZOMITE is a mineralized, compacted volcanic ash in origin and is volcanic rather than glacial. Is AZOMITE the same as volcanic ash? AZOMITE® is a mineralized, compacted volcanic ash in origin, which makes it volcanic rather than glacial. Is AZOMITE the
What is petrification Permineralization?
Geologypermineralization: form of fossilization in which minerals are deposited in the pores of bone and similar hard animal parts. petrification: process by which organic material is converted into stone through the replacement of the original material and the filling of the original pore spaces with minerals. What is the difference between permineralization and petrification? One
Which physical layers correspond to which compositional layers?
GeologyThe physical layers exactly match the compositional layers. The crust is the only compositional layer not included in the physical layers. The physical layers of the inner core and outer core form a single compositional layer. The physical layer of the asthenosphere includes the compositional layer of the crust. What are the 3 main compositional
What is the definition of divergent boundaries?
GeologyWhat is the meaning divergent boundary? Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other. What’s a
What is meant by rock forming minerals?
Geologyrock-forming mineral, any mineral that forms igneous, sedimentary, or metamorphic rocks and that typically, or solely, forms as an intimate part of rock-making processes. How do you identify rock forming minerals? Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness
