The ripples do not form in the rocks, they form in soft, sandy sediment usually in water.
The sediments are preserved after they have been buried, de-watered and turned into rock.
Metamorphic rocks can form from both igneous and sedimentary rocks

Metamorphic rocks can form from both igneous and sedimentary rocks
Sedimentary rocks form from a few different things. Sedimentary rocks form from sediment is deposited out of air, ice, wind and gravity.
Ripples.
they form
Sedimentary rocks form at the bottom of bodies of water, as more and more layers of sediment build up above them. Compared to the depths at which metamorphic rocks form, and some of the places igneous rocks form, these are indeed close to the Earth's surface.
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
Sedimentary rocks form when they undergo metamorphism. Only if they decide NOT to be Sedimentary rocks anymore.
All rocks can form from sedimentary because the rock cycle is endless.
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.
