It can be weathered. It can also be subjected to heat and/or pressure inside the earth and become a metamorphic rock, e.g. limestone can be changed to marble. If an oceanic tectonic plate is buried in a subduction zone it may melt to magma.
It can change when it is eroded and weathered.
What two thing's change a sedimentary rock into a metamorphic rock
No, high pressure alone cannot change an igneous rock into sedimentary rock; however, the reverse is true. High pressure can change sedimentary rock into igneous rock.
by how they can used erosion and weathering
To change a sedimentary rock to a metamorphic rock, you change it by time,heat, and pressure.
erosion
You can't.
Absolutely. And eventually they can become a part of a new sedimentary rock.
Igneous Rock
Weathering, erosion, deposition, compaction, and cementation.
I think pressure
By melting and cooling
