Des de diferents mirades i interessos, els joves han plantejat diverses <strong>hip\u00f2tesis<\/strong> sobre l&#8217;origen d&#8217;aquestes obertures. L&#8217;indret de les Escletxes, conegut a la literatura cient\u00edfica i excursionista, es troba protegit per llei i documentat com a <a href=\"https:\/\/mediambient.gencat.cat\/web\/.content\/home\/ambits_dactuacio\/patrimoni_natural\/sistemes_dinformacio\/inventari_despais_dinteres_geologic\/consulta_de_les_fitxes_descriptives_dels_eig\/documentos\/338_descrip.pdf\">Ge\u00f2top 338<\/a>.<\/p>\n<p>Les Escletxes s\u00f3n un conjunt d&#8217;obertures, orientades aproximadament nord &#8211; sud, al vessant esquerra de la vall del Llobregat. El fenomen natural es troba al si d&#8217;unes roques calc\u00e0ries pr\u00f2ximes a la poblaci\u00f3. Els estudiants son coneixedors dels desastres naturals que amb freq\u00fc\u00e8ncia documenten els mitjans de comunicaci\u00f3, moltes vegades amb <strong>p\u00e8rdues humanes i materials<\/strong>. Per\u00f2 avui han viscut de prop <strong>sortir de l&#8217;institut<\/strong> per con\u00e8ixer i <strong>rec\u00f3rrer el seu interior<\/strong>. En visitar-les, s&#8217;han plantejat diverses <strong>hip\u00f2tesis<\/strong>, entre elles que s&#8217;hagin produ\u00eft per l&#8217;acci\u00f3 de <strong>terratr\u00e8mols<\/strong>, per antics <strong>cursos fluvials<\/strong> o per fosses <strong>submarines<\/strong>. Conjuntament, han reconegut els materials sedimentaris a on s&#8217;ubiquen: a la part inferior argiles vermelles i a la part superior, calc\u00e0ries fossil\u00edferes. Tamb\u00e9 han reflexionat de la resposta mec\u00e0nica tant diferent que tenen les argiles quan els arriba l&#8217;aigua de pluja, estovant-se, a difer\u00e8ncia de les calc\u00e0ries.<\/p>\n<p>Despr\u00e9s de recollir moltes m\u00e9s evid\u00e8ncies, els mateixos estudiants se n&#8217;han adonat que la interpretaci\u00f3 m\u00e9s factible podria ser la d&#8217;un <strong>lliscament de blocs en el vessant<\/strong>, facilitada per la disposici\u00f3 inclinada dels estrats calcaris sobre dels argilosos. Aquesta interpretaci\u00f3 l&#8217;hem aplicada amb la seg\u00fcent <strong>visita dels carrers de la poblaci\u00f3<\/strong>, identificant desnivells, esquerdes d&#8217;edificis i altres possibles conseq\u00fc\u00e8ncies als habitatges.
