What is the rock cycle?

Question

Anyone knows?

Answer 1

i know!!! it is the cycle of rocks from igneus to sedimentary and to metamorphic....

Transition to igneous
When rocks are pushed deep under the Earth's surface, they may melt into magma. If the conditions no longer exist for the magma to stay in its liquid state, it will cool and solidify into an igneous rock. A rock that cools within the Earth is called intrusive or plutonic and will not cool very rapidly producing a coarse-grained texture. As a result of volcanic activity, magma may cool very rapidly while being exposed to the atmosphere and are called extrusive or volcanic rocks. These rocks are fine-grained and sometimes cool so rapidly that no crystals can form and result in a natural glass, such as obsidian. Any of the three main types of rocks can melt into magma and cool into igneous rocks.

Transition to metamorphic

This diamond is a mineral from within an igneous or metamorphic rock that formed at high temperature and pressure.Rocks exposed to high temperatures and/or pressures can be changed physically or chemically to form a different rock, called metamorphic. Regional metamorphism refers to the effects on large masses of rocks over a wide area, typically associated with mountain building events within orogenic belts. These rocks commonly exhibit distinct bands of differing mineralogy and colors, called foliation. Another main type of metamorphism is caused when a body of rock comes into contact with an igneous intrusion that heats up this surrounding country rock. This contact metamorphism results in a rock that is altered and re-crystallized by the extreme heat of the magma and/or by the addition of fluids from the magma that add chemicals to the surrounding rock (metasomatism). Any pre-existing type of rock can be modified by the processes of metamorphism.

Transition to sedimentary
Rocks exposed to the atmosphere are variably unstable and subject to the processes of weathering and erosion. Weathering and erosion breaks the original rock down into smaller fragments and carries away dissolved material. This fragmented material accumulates and is buried by additional material. While an individual grain of sand is still a member of the class of rock it was formed from, a rock made up of such grains fused together is sedimentary. Sedimentary rocks can be formed from the lithification of these buried smaller fragments (clastic sedimentary rock), the accumulation and lithification of material generated by living organisms (biogenic sedimentary rock - fossils), or lithification of chemically precipitated material from a mineral bearing solution due to evaporation (precipitate sedimentary rock). Clastic rocks can be formed from fragments broken apart from larger rocks of any type, due to processes such as erosion or from organic material, like plant remains. Biogenic and precipitate rocks form from the deposition of minerals from chemicals dissolved from all other rock types

Answer 2

Lava is erupted onto the surface and (in this case - can also be intruded as a pluton/batholith) becomes an igneous granite. Over time, various weathering forces (wind, water, whatever) break that granite into small pieces that get blown somewhere. These pieces form sedimentary deposits, in this case let's just say quartz (silica) granules. Increasing weight of sediment on top of sediment forces them deeper and deeper, where heat and pressure finally cement the small clasts together into a solid sedimentary sandstone (in this case). It may go back to the surface and be exposed, it may not. Someday, with increasing pressure and temperature, the quartz sandstone will be metamorphosed into a quartzite, which may or may not be exposed. Go into the future some more, and this metamorphic rock can be put under so much heat and pressure that it completely melts, becoming new magma that may or may not ever be erupted again. Keep in mind that the rock cycle is not that simple. An igneous rock can go straight to being a metamorphic rock. A sedimentary rock can become another kind of sedimentary rock. A metamorphic rock can be turned into a sedimentary rock. A sedimentary rock can be turned directly into magma, etc.

Answer 3

The rock cycle describes paths that rock go on in natural geologic processes.

Rocks start as liquid magma and cool into an igneous rock. They are then weathered and deposited to form a sedimentary rock, and then can be buried, heated, and streached to become a metamorphic rock. If buried enough, the rock can re-melt and start over.

This is the standard path, but each rock has it's own story. Igneous rocks can be turned into metamorphic rocks, or melted; sedimentary rocks are commonly eroded and put into a new sedimentary rock; and metamorphic rocks can also be eroded and turned into sedimentary rocks. The possibilites are endless, because the cycle never ends. It will continue to make and reform rocks as a result of plate tectonics.

Answer 4

It's a female rock having her cycle.

Answer 5

عندما تبدأ الماجما بالتيلور نتيجة عملية التبريد تتشكل الصخور النارية فاذا كانت عملية التبريد على السطح تشكلت الصخور النارية السطحية واذا كانت عملية التبريد تحت السطح تشكلت الصخور النارية الجوفية واذا ما تعرضت الصخور النارية لعملية التجوية والتعرية تتشكل الرسوبيات التي بدورها اذا تعرضت لعملية الضغط والتراص تتشكل الصخور الرسوبية اذا ما تعرضت الصخور النارية والصخور الرسوبية لعملية الضغط والحرارة فانها تتشكل الصخور المتحولة

Answer 6

it might be the name of the cycle used by Fred Flinstones...

ya ba daaba dooo...

Answer 7

i do but i can't think of it right now bcos im on vacaztion!!!
