Llavors s&#8217;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 de color blanquin\u00f3s i un d\u2019inferior vermell\u00f3s.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-full wp-image-14196\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2022\/02\/PHOTO-2022-02-16-15-29-01.jpg\" alt=\"\" width=\"238\" height=\"300\" \/>Per descobrir de quins materials es tractava han fet un seguit de proves en ambdues roques, com 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. <\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">A continuaci\u00f3 s\u2019han endinsat en 4 escletxes i han mesurat la direcci\u00f3, l\u2019amplada i la profunditat de cadascuna.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-14195 alignleft\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2022\/02\/IMG_20220216_122904.jpg\" alt=\"\" width=\"190\" height=\"300\" \/>Per concloure han fet una posada en com\u00fa de totes les dades i han dedu\u00eft com s\u2019havien format Les Escletxes. Han arribat a la seg\u00fcent conclusi\u00f3: com qu\u00e8 les roques calc\u00e0ries es degraden a causa de la lleugera acidesa que cont\u00e9 l&#8217;aigua de la pluja, aquest efecte durant milions d\u2019anys ha provocat que les esquerdes de les roques calc\u00e0ries s&#8217;anessin fent m\u00e9s grans i profundes fins a permetre a l&#8217;aigua<\/span><span style=\"font-family: helvetica, arial, sans-serif; font-size: 14pt;\"> arribar a les argiles inferiors. Com l&#8217;aigua fa que les argiles es tornin toves, aix\u00f2\u00a0 juntament amb la pendent ha provocat que les calc\u00e0ries llisquin vessant avall fins a formar les Escletxes que veiem avui dia. <\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">Finalment han conegut la problem\u00e0tica de les cases del Papiol, que tamb\u00e9 es troben afectades per esquerdes a les fa\u00e7anes i han fet d\u2019arquitectes proposant diverses solucions per evitar l\u2019aparici\u00f3 d\u2019aquestes.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\"> Enhorabona per la gran feina realitzada!
