岩石循环
Introduction
岩石中可用自然受到形状和大小的变化。岩石循环的过程是一个标准的概念研究地质管理方面的过渡状态的岩石。在自然界发现的岩石在一定时期内不断循环。这些岩石经历的不同阶段化学和物理变化,改变其结构。三个关键形式在自然界发现的岩石沉积、变质岩和火成岩。
Rock cycle
岩石循环过程,定义了岩石在很长一段的过渡。在自然界中发现的岩石在长期不断的转换和过渡状态,他们从不保留原来的形状。Okewale & Coop(2020)认为,一般来说,有三个突出的岩石类型在自然界发现的沉积、变质岩和火成岩。岩石主要是受外部环境条件的影响。这些岩石不断发生变化,他们要么改变形状或被破坏时的平衡条件。
岩层周期和相关的风化过程不断滋养地球矿物含量。因此,通过岩石循环的过程中,一种岩石与某些特征转换成一种不同的岩石。这一过程或岩石循环加速几个流程,如地球的构造活动板块,枯萎的岩石和其他侵蚀过程不断循环的岩石。
Figure 1: rock cycle
Classification of rocks
形成的岩石,受到一些自然过程分类主要分为三个不同的形式。这些岩石提到火成岩、沉积岩和变质岩。
Igneous rocks
这些岩石主要由呃冷却凝固过程发生的岩浆,岩浆。这种突出的岩石被发现在地球表面和侵入岩在表面之下,发现这些也称为火成岩的岩石(sandatlas 2022)。这些类型的岩石的最常见的例子是花岗岩和玄武岩。
Figure 2: igneous rocks
Sedimentary rocks
这种类型的岩石通常是由液体的沉积物保健称为沉积岩。形成的沉积岩也由于风化和侵蚀的过程。砂岩、泥岩和灰岩是沉积岩的主要例子。
Metamorphic rocks
变质岩是在地球表面找到。分类这些岩石化学成分的基础上,进行矿物的内容和结构。石英岩、大理石、片岩、片麻岩和千枚岩的变质岩的最常见的例子(科学院院刊2022)。下面这些岩石也形成地球表面由于高压力和温度。
Figure 3: Metamorphic rocks
Rock cycle: transformation to igneous
过渡到火成岩岩石时被进一步深度的地球表面,然后他们熔化成岩浆状态。如果不满足此条件进一步帮助保留的岩浆液态,然后岩浆将固体和成为一个火成岩。
Rock cycle: metamorphic transition
在岩石周期的这个阶段,岩石进一步暴露在非常高的温度和压力。根据古代et al。(2018),通常这些岩石经历极高的温度和压力,帮助他们转变的过程。此外,这些过程有助于转换他们的物理和化学状态的岩石,从而形成变质岩。
Rock cycle: sedimentary transition
岩石进一步暴露于一个彻底的环境不稳定,受条件完全改变了岩石的风化和侵蚀。据Husson &彼得斯(2018),这些过程将岩石分解成小块,进一步会带走体内的溶解的材料。通过阶段,古典和有机沉积岩形成,在第一种情况下;由于化学沉积形成的岩石表面的母岩和有机岩石沉积的植物和动物的残骸有助于这些岩石的形成。
Conclusion
岩石发现整个地球都受到各种各样的转换和他们进行化学和物理变化。岩石的这种转变在美国是由于各种自然风化和侵蚀之类的事件。这些常数转换在岩石的岩石循环相关的方面。岩石循环的过程有助于火成岩的形成,沉积岩和变质岩的三种主要形式的岩石中发现的环境。
FAQs
Q1。三种主要类型的岩石是什么?
答。地球上发现的最突出的岩石形成火成岩、变质岩和沉积岩。这些不同的化学和物理特征和受到长期的过渡。
Q2。科学研究的岩石被称为什么?
答。岩石称为岩石学的科学研究。这个分支的研究提到了岩石及其相关特征的起源。这被认为是一个主要学科领域的地质学。
第三季。三种类型的沉积岩是什么?
答,沉积岩的三种类型。经典的沉积岩是由于机械风化作用形成的。由于沉积形成的化学沉积岩母岩表面的化学物质和有机沉积岩是由植物和动物的残骸。
第四季度。这些因素决定了岩石的名称和属性?
Ans。硅含量存在于岩石和属性决定了它的名字。硅酸盐矿物是地球上丰富的岩石中发现。
