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.
What two thing's change a sedimentary rock into a metamorphic rock
a rock that cAN CHANGE TO IGNEOUS, METAMORPHIC, AND SEDIMENTARY
To change a sedimentary rock to a metamorphic rock, you change it by time,heat, and pressure.
Metamorphic rock
erosion
You can't.
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
Melting.
Sedimentary rocks change to metamorphic the same way any other rock would: through heat and pressure.
I think pressure
Igneous Rock
