Limestone, a sedimentary rock, when subjected to heat and pressure may become marble, a metamorphic rock. Shale under pressure becomes slate.Which one of the following is a metamorphic rock A.Granite.B.Shale.C.Slate.D.Limeston相关知识点: ...
Marbleis a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Which metamorphic ro...
Metamorphic Rocks: Metamorphic rocks are just one of the three types of rocks that are found on Earth. These rocks are made through pressure and heat that is made deep within the Earth. Answer and Explanation:1 The metamorphic rocks that are foliated are slate, schist, phyllite, and gneiss...
A.层理构造不同层中的有时成分不同 | The components of different layers in bedding structure are not the same.B.片理构造各部分的成分不同 | The components in all parts of schistosity structure are different.C.片理构造是通过矿物的定向排列和平行的裂纹表现出来 | Schistosity structure is performed ...
(45) marble, a metamorphic rock. Shale under pressure becomes slate. The primary purpose of the passage is toA.differentiate between and characterize igneous and sedimentary rocksB.explain the factors that may cause rocks to change in form
Is Marble or Granite Better for Your Home? Marble and Granite vs. Other Options What Is Marble? Marble is a metamorphic rock that’s transformed out of sedimentary stone. Originally, marble began as limestone and metamorphosized into marble under extreme heat and pressure. The primary component...
These lighter materials must have escaped, leaving a residue of heavy stuff. The reason for this is not hard to guess, bearing in mind the heat of the Sun. The inner planets and most of the asteroids are made of rock and metal, which can survive heat, but they contain very little ice...
For example, granite, an igneous rock, may be metamorphosed into a gneiss or a schist. Limestone, a sedimentary rock, when subjected to heat and pressure may become (45) marble, a metamorphic rock. Shale under pressure becomes slate.The primary purpose of the passage is to A.differentiate ...
Is siltstone a sedimentary rock? What type of sediment undergoes the most compaction as it lithifies to sedimentary rock? Which metamorphic rocks are foliated? Which metamorphic rocks have a nonfoliated texture? What is an organic metamorphic rock?
