Why are extrusive igneous rocks not coarse grained?
Because the rapid cooling does not allow much time for crystal growth.
Why does slower cooling result in purer crytsalS?
Slower cooling allows the atoms time to arrange in a crystalline form, whereas faster cooling freezes the atoms in position before they can all arrange themselves in the crystalline structure.
A major cause for the rapid growth of business was what?
Mass productionMass production, the availability of the ready markets and rapid population growth rate are the major causes for the rapid growth of business.
How does fine granied form?
rapid cooling
What is the Crystal size of lava?
When the magma reaches the surface, it is called lava. The rate at which the magma cools determines the kind of igneous rocks that are formed. Faster cooling surface lava creates rock that is fine grained or aphanitic. The rapid cooling doesn't allow large crystals to form. The slower cooling that takes place underground allows larger crystal formation. Granite is an example of this type of rock formation.
Why are extrusive igneous rocks not coarse grained?
Because the rapid cooling does not allow much time for crystal growth.
What is the type of crystal grain that forms when molten rock cools quickly?
Small crystal grains form from rapid cooling of magma resulting in an aphanitic rock texture.
Does cooling rate affect solubility?
slower rates of cooling will create larger crystals, rapid cooling allows little time for element accumulation in the crystal, therefore, the crystals created will be smaller. larger, visible crystals in igneous rock indicate that the magma was slow cooling, usually at depth. much smaller crystals in igneous rock indicate rapid cooling of lava, usually at or near the surface. crystals in igneous rock will grow larger and have more to accumulate material for their growth the more they have at their crystallization temperature.
Why does slower cooling result in purer crytsalS?
Slower cooling allows the atoms time to arrange in a crystalline form, whereas faster cooling freezes the atoms in position before they can all arrange themselves in the crystalline structure.
What do large crystal grains in an igneous rock indicate?
A vesicular igneous texture generally indicates rapid cooling.
Why population growth rapid after war?
because it did happen
How are intrusive rock different from with extrusive rocks?
Intrusive Rocks Intrusive rocks are characterized by large crystal that forms deep underground. Extrusive Rocks They are characterized by fine-grained textures because their rapid cooling at or near the surface.
What size is pumices crystles?
The glasses in pumice actually has no crystalline structure because of their rapid cooling.
Why does external growth lead to rapid expansion?
External growth usually leads to rapid expansion. This is because when we have a large influx of external growth, the capital market also grows. It therefore leads to circulation of currencies.
What type of crystal forms when igneous rocks cool too quickly?
Actually, if lava cools quickly enough, there can be situations where no crystallization takes place at all. Such is the case with obsidian. Rapid cooling usually translates into small crystal formation.
What are crystal?
crystal lattice means atoms of the lattice are arranged in a regular manner and every atom or ion in the structure have same property with the remaining atoms or ions in the structure
What is the textural difference between coarse-grained phaneritic and fine-grained aphanitic rocks?
Phaneritic rock has visible identifiable crystal grains. Aphanitic rock has crystal grains that are too small to be visible with the naked eye. In igneous rock, the difference is due to the amount of time spent in cooling. Long term cooling of magma underground leads to large crystals, rapid cooling of lava above ground leads to small crystal texture.
