... Get the Brainly App Download iOS App While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from pre-existing rocks. Answer:Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". ... As a consequence, metamorphic rocks are always more dense than their original material, and also much less susceptible to erosional breakdown. Metamorphic rocks are rocks that have changed from one type of rock to another. This reddish colour due to diffusion of iron in crystalline and metamorphic rocks makes it one of the important property of these soils. Sedimentary rocks can form by each of the following processes EXCEPT Choose one: A. solidification from a melt. C. by the precipitation of minerals from water solution. Clastic rocks originated from the breakdown of other rocks (could be sedimentary, igneous, or metamorphic) due to weathering and erosion. Answer: metamorphic rocks arise from the transformation existing rock types,in a process called metamorphism ,which means "change IN form".....they may be formed simply by being deep beneath the earth's surface , subjected to high temperatures and the great pressure of rock layers above it •Examples of sedimentary rocks include limestone, sandstone, mudstone, greywacke, chalk, coal, claystone and flint. •Sedimentary rocks cover the majority of the Earth’s rocky surface but only make up a small percentage of the Earth’s crust compared to metamorphic and igneous types of rocks. They are called clastic because they are composed of fragments of geological detritus. D. from shell fragments or carbon-rich relicts of plants. metamorphic rocks are created by the physical and chemical alteration by heat and pressure of an existing igneous or sedimentary meterial into a denser form. As per Wikipedia, “”Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means “change in form””.The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change. [1] The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical change. New questions in Geography India is the second largest producer of sugarcane only after_________. Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form. These rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which transforms the existing rock into … The formation of sedimentary rock occurs by several processes over millions of years. B. by the cementing together of loose grains of pre-existing rock. Non-clastic sedimentary rocks are mostly conposed of chemical precipitate out of solution (eg. Sedimentary rock formation occurs when igneous, metamorphic, or other sedimentary rocks are exposed to the unyielding forces of nature found on the Earth's surface. How do clastic rock differ from non clastic rock in terms of process of formation 1 See answer BadbutGood BadbutGood Clastic rocks are originated from the breakdown of the rocks (igneous, metamorphic, sedimentary) while Non clastic rocks are formed because of chemical precipitate.
