Metamorphic rocks are caused by heat and are melted into another rock, igneous. Igneous are formed from volcanic eruptions and can usually fall into waters, sedimentary. Sedimentary rocks are sediments of any of these rocks (metamorphic, igneous) and these sediments arewashed into rivers, lakes, streams, etc. The sediments are then piled over and over and smoothed by the water to form a rock. Then, the whole process goes over. Basically, a rock cycle.

Hope this helped!

Metamorphic rocks are formed when pre existing rocks are subjected to heat or pressure while igneous rocks are formed due to the molten lava from volcanoes and sedimentary rocks are formed from sediments.
