There are 3 main types of rocks:
Igneous – formed from molten magma which crystallises within the earth or is erupted onto the earth’s surface
Sedimentary – composed of material like sand and mud which has come from the wearing down of older rocks.
Metamorphic – igneous or sedimentary rocks which have been transformed by high pressures, high temperatures, or both.

A metamorphic rock can become igneous material where subduction forces the rock through the mantle and into the Earth's core - this occurs where plates collide.
Sedimentary rocks can form from any eroded surface material (including metamorphic rock) that settles somewhere and becomes hardened.

you may in simple terms lookup 'rock cycle' on google or in a e book and it could have it yet i'm fantastically useful the igneous rock in simple terms has to bypass by using erosion to surn inot sediment, and then compaction (so each and all the sediment is being prepare) to alter right into a sedimentary rock. desire that helped!

you are asking the question other way round . Igneous rocks and sedimentary rocks undergo changes due to extreme environmental conditions . morph=>change .....

You'd have to melt it down deep in the earth to make it igneous again. (And spit it out a volcano or something). You'd have to grind it up, layer it in a stream or lake or ocean, and bury it deep and long (sounds naughty) to get a sedimentary rock.
