Above A large number of many years, igneous rock breaks apart (weathers), and also the bits of rock (sediments) are moved (eroded) by wind, drinking water, ice, and gravity. The sediments form layers; layers in the vicinity of The underside are compacted by the burden of levels over.
Sedimentary and igneous rocks could also grow to be metamorphic rocks every time they come in direct contact with magma beneath Earth’s surface and sizzling h2o (h2o within Earth heated by magma).

How can igneous rocks variety? Remedy Igneous rocks kind by liquid magma cooling since it gets nearer to the surface Discover More Here of Earth. Because the magma cools, it varieties igneous rock that will break apart about A large number of yrs to kind sediment.
Sedimentary rock has levels referred to as strata. Sedimentary rocks are formed from sediments of igneous, metamorphic, and sedimentary rock. Sediments sort as these rocks are weathered eventually; the sediments are moved (eroded) and deposited into layers. The sediments inside the layers are compacted by the burden in the levels earlier mentioned and cemented by minerals deposited by water flowing through the layer. Sedimentary rocks protect evidence, as fossils, of earlier daily life on this planet.
