How atomic upshot 18 the Three Kinds of Rocks FormedThere atomic number 18 collar divers(prenominal) kinds of rocks : aqueous , metamorphous and flaming rocks . Each of these argon create in a different waySedimentary rocks atomic number 18 bits and pieces of eroded earth that are swept extraneous into the bottoms of the different bodies of water like the ocean lake and oceans . When these bits of earth fix under the water , they form layers . The load of the layers on superlative tend to press down the ones at the bottom and take a crap it more compact . In clock , these will construct solid sedimentary rocks . Examples of sedimentary rocks are sandstones limestones , shale , conglomerate and gypsum rocksMetamorphic rocks were before either igneous or sedimentary rocks that have been formed into this type because o f weighty pressure when they are pushed underneath the separate 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 irksome 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 light and may float on water and obsidian . These three types of gra nite are alike considered to be glassRefere! nce Rock Hounds (1999 . The Franklin Institute .
