What methamorphic rock forms at very high pressures but moderately low temperatures associated with subduction of oceanic crust and sediments?
Blueschist is a metamorphic rock that forms under high pressures but low temperatures associated with subduction zones. It typically contains minerals such as glaucophane and lawsonite, and its unique blue color is due to these mineral compositions.
Which of the following metamorphic facies are characteristic of burial metamorphism?
Zeolite and prehnite-pumpellyite facies are characteristic of burial metamorphism. These facies typically occur at low to medium pressures and temperatures, representing the early stages of metamorphism when sediments are first buried and compacted.
When does a glacier deposit its load?
A glacier deposits its load when the ice melts, releasing the sediments and rocks it carried. This can happen when the glacier reaches lower elevations or warmer temperatures, causing the ice to melt and the sediments to be left behind.
How does subduction at converging plate boundary's lead to the formation of volcanoes?
When the denser plate subducts (usually the oceanic crust) it gets pushed down into the hot asthenosphere and melts a little. this causes the magma created from the melting to rise up and shoot out of the earth's crust, forming a volcano.
How do lithogenous sediments differ from biogenous sediments?
Lithogenous sediments come from the land They result primarily from erosion by water, wind, and ice Biogenous sediments originate from organisms The particles in these sediments come from shells and hard skeletons. Although lithogenous sediments represent the largest total volume, biogenous sediments cover a greater area of sea floor
How do we classify rocks as igneous and sedimentary and metamorphic?
Igneous rocks form from the cooling and solidification of molten lava or magma. Sedimentary rocks are created from the accumulation and compaction of sediments like sand, mud, or organic material. Metamorphic rocks form when existing rocks are subjected to high temperatures and pressures, causing them to recrystallize without melting.

Blueschist is a metamorphic rock that forms under high pressures but low temperatures associated with subduction zones. It typically contains minerals such as glaucophane and lawsonite, and its unique blue color is due to these mineral compositions.
How does the rock cycle recycle rocks?
The rock cycle can recycle rocks from melting and giving pressures to sediments.
Which of the following metamorphic facies are characteristic of burial metamorphism?
Zeolite and prehnite-pumpellyite facies are characteristic of burial metamorphism. These facies typically occur at low to medium pressures and temperatures, representing the early stages of metamorphism when sediments are first buried and compacted.
Diagenesis refers to?
Diagenesis refers to the physical and chemical changes that sediments undergo as they are compressed and cemented into sedimentary rocks. It occurs at relatively low temperatures and pressures and can involve processes like mineral growth, recrystallization, and compaction.
What processes occur that change a sedimentary rock into an igneous rock?
Sedimentary rock can be turned into lave or magma by contact with either of the substances or exposure to extreme heat. When the lava or magma cools, it becomes igneous rock.Students who are using wiki.answers.com could be advised that copying word for word is plagerizm.
Give one type of example of how one type of rock can change into another type of rock?
Sedimentary rock can change into metamorphic rock through the process of heat and pressure. This occurs when sedimentary rocks are buried deep within the Earth's crust, subjected to high temperatures and pressure, causing the minerals to recrystallize and form new structures characteristic of metamorphic rocks.
What does heat from earths interior and pressure from overlying rock transform te remains of marine sediments into?
Heat from Earth's interior and pressure from overlying rock transform the remains of marine sediments into metamorphic rocks, such as slate, marble, or schist. This process, known as metamorphism, causes the minerals in the sediments to recrystallize and reorganize, resulting in a new rock with different properties than the original sediment.
Where does coal come from?
Coal is a fossil fuel that forms from the remains of plants that lived millions of years ago in swampy environments. Over time, these plant materials were buried and subjected to high temperatures and pressures, which caused them to transform into coal.
Heat from earths interior and pressure from overlying rock transform the remains of marine sediments into?
metamorphic rocks, such as marble or quartzite, through the process of recrystallization. This transformation occurs deep within the Earth's crust where high temperatures and pressures cause the minerals in the sedimentary rocks to reorganize and form new crystal structures.
Are sediments buried 3 to 4 km deep experience temperature that start the chemical and mineral changes that cause cementation?
Yes, sediments buried 3 to 4 km deep experience temperatures and pressures that can trigger chemical and mineral changes leading to cementation. This process involves the precipitation of minerals, like quartz or calcite, in the pore spaces between sediment grains, binding them together to form rock. The increased temperature and pressure at such depths can facilitate this cementation process.
How do you recrystallize the sugar stirred into a cup of tea?
Evaporate the liquid away. This would also leave other sediment so to get just the sugar you would probably then have to use a centrifuge to separate the various sediments.
