How can an igneous or metamorphic rock change into a sedimentary rock?

Answer 1

A sedimentary rock can change from that to a metamorphic rock then into an Igneous rock. e.g. Mudstone (sedimentary) is in the Zone of Diagenesis, when it is subjected to regional metamorphism (in mountain belts) it changes from a mudstone to a slate (low grade) then to a Phillite (medium grade) then a Schist (medium) then a gneiss (high grade) then into a Milonite (high grade) then once past the line of partial melting it has so much pressure and so much temperature that it turns into an Igneos rock. This is the basic explanation of this. If you want to know more, just ask me.
Sedimentary rocks are changed into metamorphic by being buried deep enough that the heat and pressure alter their text, mineralogy, or other characteristics.

Answer 2

There are a lot of processes involved that transform a sedimentary rock into an igneous or metamorphic rock. But in short detail a sedimentary rock becomes metamorphic when it is exposed to pressure and or heat. The chemical composition of the rock doesn't change once its been metamorphosed, but its physical properties to. The rock body doesn't ever completey melt, it remains mostly solid. Now for a sedimentary rock to become igneous, it must be completely melted. When this happens the physical and chemical compositions of the rock are now different then what is was as a sedimentary rock.

Answer 3

there are several ways such as heat & pressure, melting, chemical weathering, compression, compaction & cementation, but it depends on the kind of rock it is for what process it has to go through.

Answer 4

Metamorphic rocks form when pressure and/or temperature conditions are enought to alter an igneous or sedimentary rock. For example- a sedimentary sandstone can metamorphose into a metamorphic quartzite. Commonly, metamorphic rocks form during mountain building or burial (during which times both temperature and pressure increase).

Answer 5

Sedimentary rocks change to metamorphic rocks due to intense heat and/or pressure at considerable depths beneath the earth's surface.

Answer 6

After thousands of years, igneous and metamorphic rock break down into tiny sediments. after millions of years those sediments turn into sedimentary rock

Answer 7

When a sedimentary or igneous rock subjected to "high temperature and pressure", it changes to a metamorphic rock.

Answer 8

By undergoing the process of metamorphism.

Answer 9

through heat and pressure
