\"\"Divendres 26 de mar\u00e7 del 2021, l\u2019alumnat de 6\u00e8 B de Prim\u00e0ria de la classe “Mamma Mia” de l\u2019Escola Miquel Mart\u00ed i Pol de Sant Feliu de Llobregat, han treballat com aut\u00e8ntics espele\u00f2legs per descobrir les raons que han dut el territori del Papiol a tenir l\u2019estructura que avui dia podem observar.<\/p>\n

Dividits per equips de treball, han fet una petita introducci\u00f3 dels conceptes b\u00e0sics de geologia, com ara: escletxe, vessant, roca calc\u00e0ria, argila, etc. A partir d\u2019aqu\u00ed i observant el quadern de treball, han fet algunes hip\u00f2tesis de com podrien haver-se format aquestes escletxes. S\u2019han adonat que es trobaven en una vessant amb dos tipus de substrat o material: un m\u00e9s blanquin\u00f3s i un de m\u00e9s vermell\u00f3s.<\/p>\n

Despr\u00e9s s\u2019han dirigit cap a les zones on hi havia aquests materials i han fet tot un seguit de proves per tal de descobrir quin nom rebien aquests. Han treballat de valent per descobrir la consist\u00e8ncia, la permeabilitat i si hi havia reacci\u00f3 o no en contacte amb \u00e0cid. Han acabat concloent que els materials observats eren roca calc\u00e0ria i argila.<\/p>\n

Despr\u00e9s del descans, han iniciat l\u2019aventura de baixar a algunes de les escletxes i prendre mesures d\u2019amplada, fond\u00e0ria i orientaci\u00f3 de cadascuna d\u2019elles per despr\u00e9s poder comparar-les.<\/p>\n

Finalment, a la posada en com\u00fa, han trobat la resposta de perqu\u00e8 i com s\u2019havien format aquestes escletxes: Degut a la lenta degradaci\u00f3 que pateix la roca calc\u00e0ria amb la lleugera acidesa de la\"\" pluja, es van creant esquerdes cada vegada m\u00e9s grans fins que arriben al substrat argil\u00f3s. Quan aix\u00f2 passa, l\u2019argila es mulla i es torna pastosa, de manera que el moviment d\u2019aquest terreny pel pes de la roca calc\u00e0ria i la inclinaci\u00f3 de la vessant, fa que els blocs de roca es vagin despla\u00e7ant, provocant cada vegada m\u00e9s separaci\u00f3 entre ells i les escletxes.<\/p>\n

Degut a aquests fets, han descobert la problem\u00e0tica que pateixen les cases de la zona del Papiol que estan constru\u00efdes en aquesta mateixa vessant.<\/p>\n

Per despedir-se, i abans d\u2019anar a dinar, han fet el ball del Mamma Mia! que ha pogut gaudir d\u2019un ampli p\u00fablic!<\/p>\n
