| YES THIS IS RIGHT DOAA, sedementary rocks are made in layers that cemented in layers at the bottom of oceans and sea,and it take years and years in forming it.  while the igneous rocks are made from very hot melted minerals and gases which comes out from the volcanoes.,and when it cools at the surface of the earth it becomes igneous rocks | |
