What are characteristics of intrusive igneous rocks?
GeologyIntrusive rocks are characterized by large crystal sizes, i.e., their visual appearance shows individual crystals interlocked together to form the rock mass. The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow. What are the 3 characteristics of intrusive igneous rocks?

What is a Wadati Benioff zone and how does it help to define the location of subducting plates?
GeologyA subducting plate’s path (called the Benioff-Wadati [or Wadati-Benioff] zone) is defined by numerous earthquakes along a plane that is typically inclined between 30° and 60° into the mantle. What is a Wadati-Benioff zone simple? From Simple English Wikipedia, the free encyclopedia. A Wadati–Benioff zone is an area within the Earth’s crust where earthquakes frequently

Which would have a higher porosity a well sorted sediment or a poorly sorted sediment?
GeologyThus, well sorted sediments have higher porosity while poorly sorted sediments have low porosity. Permeability refers to how easily water passes through sediments and rock. Why do well sorted sediments have higher porosity? Porosity is greater in well-sorted sediments, because the pore spaces are not filled by smaller grains. Is porosity greater in well sorted

What type of volcano is Columbia Plateau?
GeologyOver 170,000 cubic kilometers (105,633 mi) of basaltic lava, known as the Columbia River Basalts, covers the western part of the province. These tremendous flows erupted between 17 million – 6 million years ago. What kind of volcano is Columbia Plateau? The Columbia Plateau flood basalts are a notable example of a “Large Igneous Province,”

What is the definition of reverse fault in science?
GeologyDefinition of reverse fault : a geological fault in which the hanging wall appears to have been pushed up along the footwall. What is a reverse fault kid definition? A reverse fault (if steeply dipping) or thrust fault (if shallowly dipping) is a fault where the fault plane dips toward the upthrown block. It is

Is Serpentine jewelry safe?
GeologyHowever, the green serpentine gemstones most often used in jewelry making are part of the serpentine subgroup of stones known as antigorite, as this form of serpentine is safe for drilling and shaping unlike other forms such as chrysotile, which is used in asbestos. Is serpentine toxic? Serpentine is not a toxic rock. It sometimes

Is Super white quartzite or dolomite?
GeologyDolomite MarbleDolomite Marble. What is the difference between quartzite and dolomite? Unlike granite or quartzite, dolomite is a sedimentary rock, which forms naturally when limestone comes in contact with magnesium-rich groundwater and undergoes a chemical change. It comes in shades of white or gray, and usually contains streaks that allow it to resemble marble better

Is soil a product of weathering?
GeologySoils develop because of the weathering of materials on Earth’s surface, including the mechanical breakup of rocks, and the chemical weathering of minerals. Soil development is facilitated by the downward percolation of water. Is soil a weathering? Weathering describes the means by which soil, rocks and minerals are changed by physical and chemical processes into

Which mass wasting process has the slowest rate of movement?
GeologySoil creep is a slow and long term mass movement. What is the slowest type of mass movement process? Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements. What type of mass movement is the slowest fastest? Mass movements differ from one another based

What are the three ways that form ores?
GeologyThere are three major types of ore genesis: internal processes, hydrothermal processes, and surficial processes. Ore can accumulate through geologic activity, such as when volcanoes bring ore from deep in the planet to the surface. This is called an internal process. How are ores formed? Deposits of minerals form when a medium that contains and
