Els alumnes de Ci\u00e8ncies de la Terra de 2n de Batxillerat de l\u2019Institut Llu\u00eds de Requesens<\/strong> de Molins de Rei i l\u2019Institut Frederic Mompou<\/strong> de Sant Vicen\u00e7 del Horts van visitar les Escletxes del Papiol el dia 20 de febrer per estudiar els processos de vessant i els riscos naturals<\/a>.<\/p>\n

\"\"<\/a>En primer lloc van fer un plantejament de problemes que podien comportar les escletxes i van formular hip\u00f2tesis per explicar aquest proc\u00e9s. Van situar-les geogr\u00e0ficament i van diferenciar entre el material superior i l\u2019inferior. A partir de l\u2019estudi de la resist\u00e8ncia i la consist\u00e8ncia d\u2019aquests o la reacci\u00f3 amb l\u2019\u00e0cid clorh\u00eddric van identificar els materials com calc\u00e0ries i argiles respectivament. Tamb\u00e9 les van representar en una columna estratigr\u00e0fica, situant-les sobre el s\u00f2col Paleozoic de pissarres.<\/p>\n

\"\"<\/a>Per l\u2019estudi m\u00e9s detallat van obtenir diverses dades com la direcci\u00f3, la inclinaci\u00f3, la profunditat i el despla\u00e7ament horitzontal i vertical\u00a0 de sis escletxes. Amb totes les dades recollides van poder elaborar\u00a0 un model te\u00f2ric sobre com s\u2019havien format, i \u00e9s que, degut a la lleugera acidesa de les pluges les calc\u00e0ries reaccionen i s\u2019erosionen m\u00e9s f\u00e0cilment, produint-se esquerdes en aquestes. Aquestes esquerdes s\u2019han anat fent m\u00e9s profundes fins a arribar a les argiles, i el comportament d\u00factil d’aquestes provoquen un lliscament de les calc\u00e0ries.<\/p>\n

D\u2019altra banda van observar alguns arbres amb una morfologia del tronc corbada i \u00a0van poder deduir un altre moviment de vessant: el de reptaci\u00f3 o creep<\/em>.<\/p>\n

Finalment, van observar algunes esquerdes en les fa\u00e7anes de les cases del Papiol i van avaluar el risc d\u2019aquestes tenint en compte el valor dels bens exposats, la vulnerabilitat i la probabilitat de danys. Tamb\u00e9 van proposar mesures preventives per evitar les esquerdes en les cases del Papiol.<\/p>\n

Han gaudit d\u2019un dia molt maco i han apr\u00e8s molt sobre geologia i els riscos dels processos de vessant!<\/p>\n","protected":false},"excerpt":{"rendered":"
