Han comen\u00e7at parlant de diversos aspectes del relleu de la zona i dels fen\u00f2mens naturals relacionats amb el terreny.<\/p>\n

Despr\u00e9s de revisar el material necessari per investigar s’han posat mans a la feina. Primer han observat que Les Escletxes es troben en un vessant i han diferenciat dos tipus de materials: un de superior blanquin\u00f3s i un d\u2019inferior vermell\u00f3s.<\/p>\n

Per descobrir de quins materials es tractava han fet un seguit de proves en ambdues roques com ara comprovar la consist\u00e8ncia, la permeabilitat o veure si reaccionava amb l\u2019\u00e0cid clorh\u00eddric. Han confirmat que el material superior s\u00f3n roques calc\u00e0ries i l\u2019inferior s\u00f3n argiles.<\/p>\n

Despr\u00e9s d’esmorzar s\u2019han endinsat en 4 escletxes i han mesurat la direcci\u00f3, l\u2019amplada i la profunditat de cadascuna.<\/p>\n

\"\"Per concloure han fet una posada en com\u00fa i han dedu\u00eft com s\u2019havien format. Com que les roques calc\u00e0ries es van degradant a causa de la lleugera acidesa que cont\u00e9 la pluja, durant milions d\u2019anys les esquerdes de les roques s\u2019han anat fent m\u00e9s i m\u00e9s grans i profundes fins a permetre a l’aigua arribar a les argiles inferiors. Aquestes esquerdes cada vegada s\u00f3n m\u00e9s amples perqu\u00e8 les argiles fan que les roques calc\u00e0ries llisquin vessant avall. Aquesta \u00e9s la problem\u00e0tica de les cases del Papiol, que tamb\u00e9 es troben afectades per esquerdes a les seves fa\u00e7anes. Han fet una gran tasca, fins aviat!<\/p>\n","protected":false},"excerpt":{"rendered":"
