How atomic routine 18 the Three Kinds of Rocks FormedThere atomic number 18 collar antithetical kinds of rocks : aqueous , metamorphous and fiery rocks . Each of these argon organise in a different waySedimentary rocks ar bits and pieces of eroded earth that are swept forward into the bottoms of the different bodies of water like the ocean lake and oceans . When these bits of earth chill out under the water , they form layers . The load of the layers on transcend tend to press down the ones at the bottom and adjudge it more compact . In clock , these will acquire solid sedimentary rocks . Examples of sedimentary rocks are sandstones limestones , shale , conglomerate and gypsum rocksMetamorphic rocks were primarily either igneous or sedimentary rocks that have been formed into this type because of forbidding pressur e when they are pushed underneath the another(prenominal) rocks . When these rocks are forced to become so compact because of the heavy pressure above them , heat builds up and causes the deformation .

Examples of metamorphic rocks are schist and gneissGranite rocks come from volcanic debris that transform into rocks because of behind cooling . This snappy change in temperature happens when lava suddenly flows on the ground and traps cooling pockets of magma underneath . The cold temperature cools the lava slowly and forms the granite rocks . Examples of granite rocks are scoria , pumice which are genuinely li ght and whitethorn float on water and obsidi! an . These three types of granite are as well considered to be glassReference Rock Hounds (1999 . The Franklin Institute .
