Nā Laʻana o ka Pōhaku sedimentary 24 ʻano
24 ʻano / pahu, pahu nui 39.5x23x4.5cm
ʻO nā pōhaku he hōʻuluʻulu o nā minelala a ʻo ia nā mea nui e hana i ka pā o ka honua. Hiki ke haku ʻia ka pōhaku i kekahi ʻano mineral, e like me ka limestone i haku ʻia i hoʻokahi wale nō mineral o ka kaleka; hiki ke haku ʻia i nā minelala he nui, e like me ka granite, i haku ʻia i mau minelala he nui e like me ka quartz, feldspar, a me ka mica. ʻO ka hapa nui o nā mea e hana ana i nā pōhaku he mau mea inorganic. Hiki ke hoʻokaʻawale ʻia nā pōhaku i ʻekolu mau mahele e like me kā lākou genesis, akā no ka mea he hoʻomau ka kūlohelohe, paʻakikī e mahele maoli i ʻekolu mau lithology e like me kā mākou hoʻonohonoho ʻana. No laila, e loaʻa kekahi mau pōhaku hoʻololi, e like me ka tuff (ka lua pele a me ka hāʻule pōhaku). Hiki ke hoʻokaʻawale ʻia ʻo ia he pōhaku sedimentary a i ʻole pōhaku igneous, akā hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻāpana nui: ʻo nā pōhaku sedimentary kahi 66% o ka ʻili a ʻo nā ʻano nui o nā pōhaku ma ka ʻili. ʻO nā pōhaku i hana ʻia ma mua e lilo i detritus ma hope o ke anilā ʻana, a i ʻole nā koena o nā meaola, a pēlā aku, i kumu ʻia e ka ʻaʻai, ka lepo, a me ka petrification. Hoʻopili ʻia kēia ʻano pōhaku. ʻO ka waihona mua ma ka ʻaoʻao haʻahaʻa. ʻOi aku ka makahiki. ʻO ke kiʻekiʻe kiʻekiʻe, ʻo ka hou o ka makahiki. Kapa ʻia kēia ʻo ke kānāwai papa i hoʻopili ʻia. Ke waiho ʻia nā pōhaku, hiki ke mālama pinepine ʻia nā koena i loaʻa pinepine i nā meaola no ka manawa lōʻihi a lilo i mau mōʻalihaku ma hope o ke kanu ʻana; i nā pōhaku igneous, ʻaʻohe fossil ka hapanui.
