How a metamorphic rock could turn into a sedimentary rock and then back into a metamorphic rock?

Answer 1

By exposure to heat and/or pressure through depth of burial, directed pressure, or proximity to a magma source. Existing minerals can recrystallize, non-hydrous minerals can replace hydrous minerals, new minerals can be formed from the introduction of new ions from heated solutions, and minerals can become flattened and aligned in parallel layers.

Answer 2

The rock needs to be 100 to 200 km under the Earth's surface.

Answer 3

First, the metamorphic rock would have to be weathered to form sediment. Then, it might settle at the bottom of a stream and be naturally cemented by quartz or calcite and form sandstone. Then the sandstone might be, maybe, carried into a mine that's about to be closed because it's too hot and about a mile underground by the water. Then, they might fill the mine back up and the temperature and pressure would rise and, over a long period of time, turn the sandstone into quartzite.

Answer 4

A Metamorphic Rock could turn into a sediment rock by heat and erosion. Then the sediment rock could turn into a Sedimentary Rock by compaction and cementation. The Sedimentary Rock can turn into a Metamorphic Rockagain by heat and pressure. Metamorphic Rock (weathering and erosion Sediment Rock Sediment Rock (compaction and cementation)= Sedimentary Rock Sedimentary Rock (Heat and Pressure) = Metamorphic Rock

Answer 5

It is possible when a sedimentary r. can become a metamorphic r. because when metamorphic rocks get charged by heat and pressure, the metamorphic rock goes through a complete change which causes the metamorphic rock to become a sedimentary r.

Answer 6

A metamorphic rock could weather and erode to form sediment, which can then lithify into a sedimentary rock through processes like compaction and cementation. This sedimentary rock, if subjected to high pressure and temperature again, can undergo metamorphism to become a new metamorphic rock through recrystallization and reorganization of minerals.

Answer 7

Sedimentary rocks get turned in to metamorphic rocks by heat and pressure. They get heated by magma and convection currents, which causes the rock to change.

Answer 8

it gets weathered and eroded
