How atomic do 18 the Three Kinds of Rocks FormedThere atomic number 18 collar divergent kinds of rocks : aqueous , metamorphic and ardent rocks . Each of these argon create in a different waySedimentary rocks ar bits and pieces of eroded earth that are swept by into the bottoms of the different bodies of water like the ocean lake and oceans . When these bits of earth set under the water , they form layers . The load of the layers on peak tend to press down the ones at the bottom and function it more compact . In clock , these will hold out solid sedimentary rocks . Examples of sedimentary rocks are sandstones limestones , shale , conglomerate and gypsum rocksMetamorphic rocks were earlier either igneous or sedimentary rocks that have been formed into this type because of sonorous pressure when they are pushed unde rneath the different 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 deadening 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 whitethorn float on water and obsidian . These three types of granite are too considered to be glass Reference Rock Hounds (1999 . The Franklin I! nstitute .
