At which location is burial metamorphism most likely to occur?
Convergent boundary
What process is needed to change sedimentary rock into metamorphic rock?
The process needed to change sedimentary rock into metamorphic rock is called metamorphism. Metamorphism occurs when sedimentary rocks are subjected to high heat and pressure within the Earth's crust, causing them to recrystallize and form new mineral structures without melting. This process can happen due to tectonic forces during mountain building, or deep burial within the Earth's crust.
Do all rocks form fossils?
No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.
Why is burial usually necessary to turn a sediment into a sedimentary rock?
The key to converting sediment into sedimentary rock is often though of as being pressure. And it is only by burial that enough pressure can be generated on a layer of sediment to "press" it into sedimentary rock. With pressure and time comes what is called compaction and the expulsion of (most of) the space between the particles of sediment that were deposited. Let's look at sediments being laid down and turned into sedimentary rock.When sediments are created, moved and deposited, they can consolidate and form a layer or layers. These strata will be composed of particles of organic and inorganic material. Included will be the intersticial spaces between the sediments. Any water present in the pore spaces (and there usually is) will bring with it dissolved minerals. These can precipitate out in the spaces, and will cause cementation, which is the binding of these minerals to the particles of sediment and the "sticking together" of the sediments. Following the deposition of more material, pressure (lithostatic pressure) will build on the underlying strata. The compaction forces the layer to become more dense and to "turn to stone" over time. And sedimentary rock is the result of this process.
Why do rock fossils form in sedimentary rock and not igneous rock?
Rock fossils form in sedimentary rocks because the process of fossilization usually involves the burial and preservation of organic material in layers of sediment. Igneous rocks form from molten magma, which would destroy any organic material present, making it unlikely for fossils to be preserved in them. Sedimentary rocks, on the other hand, accumulate over time and provide the conditions necessary for the preservation of fossils.
What is deep burial of sediments?
Deep burial of sediments refers to the process where layers of sediment are deposited and subsequently buried by additional layers over time, leading to increased pressure and temperature. This process occurs in environments such as ocean basins, river deltas, or sedimentary basins. As sediments are buried deeper, they undergo diagenesis, which can transform them into sedimentary rock through compaction and cementation. This process is crucial in the formation of fossil fuels and other geological resources.

Which rock type is most likely the result of compaction and cementation of particles?
Sedimentary rock is most likely the result of compaction and cementation of particles. This process involves the gradual accumulation, burial, and lithification of sediment to form rock. Examples of sedimentary rocks include sandstone, shale, and limestone.
Can coal be organic rock?
Yes, coal is considered an organic sedimentary rock. It is formed from the remains of plants and trees that have undergone a process of burial, decomposition, and carbonization over millions of years.
What is the process of getting mummies ready for burial called?
The process of taking a corpse and preparing it for burial is called mummification.

Is burial of sediment which makes the igneous rocks?
Burial of sediment does not make igneous rock.
What process changes metamorphic rocks into sedimentary rocks?
Subduction and high pressure.

A clear fish imprint in the rock indicates that the rock is probably?
sedimentary, as clear fish imprints are often found in sedimentary rocks formed by the accumulation of sediment over time. Sedimentary rocks can preserve fossils and imprints due to the gentle burial process that allows for the preservation of organic remains.
What is the physical processes that are important in transforming sedimentary rock into metamorphic rocks?
The physical processes important in transforming sedimentary rocks to metamorphic rocks are, Pressure, Temperature, Stress, Depth of burial and Metasomatism.
