The formation of this type of rock derives directly from the solidification of the lava. We can divide them into two families: intrusive rocks and effusive rocks. Therefore The effusions have solidified above the earth’s surface. The incredible speed of cooling from lava to rock is their main characteristic.The intruders solidify under the earth’s surface. Therefore The process is much slower, allowing the crystals inside the rock to grow ( granites, diorites, gabbros ). From this content, you will able to know about what is the the rock cycle and how does it work?
Getting Know: what is the the rock cycle and how does it work?
Since there is a considerable variety of igneous rocks, it would seem logical to also think of an equal number of types of magmas. In reality, this is not the case: the extraordinary diversification of igneous rocks depends on the infinite possibilities that can occur in a chaotic process, such as magma’s cooling.
There are two main types of magmas. Magmas deficient in silicon, called primary magmas, are richer in Fe ( iron ), Mg ( magnesium ), and Ca ( calcium ); those rich in silicon, called acid magmas, are characterized by relatively higher concentrations of sodium and potassium. In these conditions, the rock appears with a very fine graininess and an apparent absence of crystals ( obsidians, pumice, basalts ).
Type of rock: It’s material and essential information
This type of rock is composed of the alteration and erosion of pre-existing rocks and organic materials. This process occurs through mechanical and chemical processes. Depending on the type of stone from which the sediments, we can distinguish three families of sedimentary rocks: the detrital rocks, the organic rocks, the chemical rocks.
The sedimentary detrital rocks formed by material eroded and transported in different ways (rivers, wind, gravity, etc.) And accumulated over the land area (continental deposits) or on the bottom of sea basins (marine deposits) or lacustrine. Loose sediments transformed into rock through long processes of compaction and lithification. The individual granules that make up the sedimentary detrital rocks can be of any nature.
Which things are involved about this rocks
It depends on whether the initial erosion involved pre-existing sedimentary, metamorphic, or magmatic rocks. Examples of detrital rocks are conglomerates, breccias, sandstones, argillites, and marls. The chemical or biochemical sedimentary rocks are deriving from the presence of solution in the water minerals.
It is emanating from the alteration of pre-existing rocks or organisms. As the solution’s physical conditions vary (for example, a rise in temperature or the evaporation of a basin), the minerals precipitate.
What is the the rock cycle, and what are organic Sedimentary rocks?
The organic sedimentary rocks formed from organic material, mainly remnants of vegetation, and lack of minerals, inorganic by definition. Such as peat, lignite, bituminous coal, anthracite ). Besides, limestone, dolomite, radiolarite, and flint belong to this group.
All rocks subjected to physical and chemical conditions other than those in which they formed can transform. If subjected to high pressures or temperatures, they undergo the transformation process called metamorphism.
Four main variables come into play in this process
#1 Pressure: determines the deformation of the minerals and controls their growth;
#2 Temperature: The lattices’ thermal agitation allows the exchange of atoms, ions, and molecules, determining some minerals’ transformation into others. Furthermore, the recrystallization of some mineral phases occur without the fusion of the material achieved.
#3 Water and gas: They are the primary carriers of new chemical elements that determine the formation of new or altered minerals;
#4 Time: They solid-state recrystallization requires a very long time to fully completed.
Metamorphic rocks are classified according to the chemical composition of the original stones ( protoliths ):
- rocks of clayey and clayey/arenaceous
- The rocks of arenaceous origin
- rocks of calcareous origin
- The rocks of acid magmatic origin
- Therefore rocks of essential and ultra-basic magmatic derivation
Is rocky material continuously reused?
Therefore In nature, the rocky material continuously reused in the lithogenic cycle, as per the following scheme.
The erosion and alteration of the rocks present on the earth’s crust’s surface by atmospheric agents create sediments. It settles and “lithify” (compact in stone).
Therefore They resurface and exposed to erosion again or metamorphose through heat and pressure within the earth’s crust, giving rise to metamorphic rocks. In turn, these too re-melt in contact with the Magna of the mantle or resurface and eroded again. Therefore On the other hand, magma can solidify (giving rise to igneous rocks);
Therefore During the cooling of igneous rocks, crystals formed. The shapes and colors of the crystals will be dictated by the nature of the rock’s predominant element. Crystallization is a slow process that takes millions of years. Each molecule seeks its place in the crystalline lattice, giving life to crystals with fascinating geometric shapes. Therefore We will re-create this process by speeding up the crystallization process and using two readily available elements: sugar and salt.
The Final word and what is the the rock cycle
Therefore These rocks also rise to the surface (and eroded) or remain inside the crust and metamorphize to give rise to new metamorphic rocks. Therefore Erosion and the earth’s internal heat are the two “engines” that provide life to the cycle. In this article, we were trying to clarify what is the the rock cycle and how does it work?
