Detailed explanation-1: -Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
Detailed explanation-2: -Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans.
Detailed explanation-3: -Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble.
Detailed explanation-4: -Igneous-they form from the cooling of magma deep inside the earth. Metamorphic-they are formed through the change (metamorphosis) of igneous and sedimentary rocks. Sedimentary-they are formed through the solidification of sediment.
