phenomena<\/strong><\/p>\n<p><strong>Surface manifestations of the karst phenomenon<\/strong>&nbsp;can very easily be observed in the area of \u200b\u200bthe Geopark.&nbsp;<strong>Deep morphologies<\/strong>&nbsp;are less visible but very widespread and include caves, pot-holes, abysses, and springs. Among the&nbsp;<strong>surface karst forms,<\/strong>&nbsp;there are the microforms, also called&nbsp;<strong><em>Karren<\/em><\/strong>&nbsp;(grooves, rainpits, etc.) and macro forms, such as dolines, closed valleys, etc.<\/p>\n<p>All the forms related to karst are created by water, which, under certain conditions, can \u201ccorrode\u201d rocks, in particular, carbonate rocks, that is, those made up of calcium carbonate. The \u201ccorrosive\u201d activity is greater the lower the temperature and the higher the concentration of dissolved carbon dioxide.<\/p>\n<p>When conditions change, in particular temperature and pressure, the opposite phenomenon may occur, namely the deposition of calcium carbonate and thus concretions are formed including&nbsp;<strong>stalactites, stalagmites, columns, castings,&nbsp;<\/strong>and<strong>&nbsp;curtains<\/strong>.<\/p>\n<p>In addition to corroding rocks, the water also performs a mechanical erosive action. This is called \u201c<strong>modeling<\/strong>\u201d, which smoothes and excavates rocky walls.<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div><\/div><\/div><div id=\"pgc-w5ea194bc792e4-0-1\"  class=\"panel-grid-cell\" ><div id=\"panel-w5ea194bc792e4-0-1-0\" class=\"so-panel widget widget_sow-editor panel-first-child panel-last-child\" data-index=\"1\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-sow-editor so-widget-sow-editor-base\"\n\t\t\t\n\t\t>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n\t<p>\t\t\t\t<a href=\"https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/1.Rocce-carsif_Karren_CaseraBordaglia.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"704\" height=\"1024\" src=\"https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/1.Rocce-carsif_Karren_CaseraBordaglia-704x1024.jpg\" class=\"attachment-large size-large\" alt=\"\" srcset=\"https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/1.Rocce-carsif_Karren_CaseraBordaglia-704x1024.jpg 704w, https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/1.Rocce-carsif_Karren_CaseraBordaglia-206x300.jpg 206w, https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/1.Rocce-carsif_Karren_CaseraBordaglia-768x1117.jpg 768w\" sizes=\"auto, (max-width: 704px) 100vw, 704px\"><\/a><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><div id=\"panel-5182-0-1-2\" class=\"so-panel widget widget_siteorigin-panels-builder\" data-index=\"3\" ><div class=\"mb panel-widget-style panel-widget-style-for-5182-0-1-2\" ><div id=\"pl-w5ea194bc7b12b\"  class=\"panel-layout\" ><div id=\"pg-w5ea194bc7b12b-0\"  class=\"panel-grid panel-no-style\" ><div id=\"pgc-w5ea194bc7b12b-0-0\"  class=\"panel-grid-cell\" ><div id=\"panel-w5ea194bc7b12b-0-0-0\" class=\"so-panel widget widget_sow-editor panel-first-child panel-last-child\" data-index=\"0\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-sow-editor so-widget-sow-editor-base\"\n\t\t\t\n\t\t>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n\t<p>\t\t\t\t<a href=\"https:\/\/www.geoparcoalpicarniche.org\/0-copertina-sez_grotta-magico-alverman\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"681\" src=\"https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/0.COPERTINA-SEZ_Grotta-Magico-Alverman-1024x681.jpg\" class=\"attachment-large size-large\" alt=\"\" srcset=\"https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/0.COPERTINA-SEZ_Grotta-Magico-Alverman-1024x681.jpg 1024w, https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/0.COPERTINA-SEZ_Grotta-Magico-Alverman-300x199.jpg 300w, https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/0.COPERTINA-SEZ_Grotta-Magico-Alverman-768x511.jpg 768w, https:\/\/www.geoparcoalpicarniche.org\/wp-content\/uploads\/2018\/01\/0.COPERTINA-SEZ_Grotta-Magico-Alverman-272x182.jpg 272w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\"><\/a><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><div id=\"panel-5182-0-1-3\" class=\"so-panel widget widget_siteorigin-panels-builder\" data-index=\"4\" ><div class=\"mb panel-widget-style panel-widget-style-for-5182-0-1-3\" ><div id=\"pl-w5ea194bc7bf1e\"  class=\"panel-layout\" ><div id=\"pg-w5ea194bc7bf1e-0\"  class=\"panel-grid panel-no-style\" ><div id=\"pgc-w5ea194bc7bf1e-0-0\"  class=\"panel-grid-cell\" ><div id=\"panel-w5ea194bc7bf1e-0-0-0\" class=\"so-panel widget widget_sow-editor panel-first-child panel-last-child\" data-index=\"0\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-sow-editor so-widget-sow-editor-base\"\n\t\t\t\n\t\t>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n\t<p><strong>Karstic rocks<\/strong><\/p>\n<p>Within the Geopark, different types of karstic rocks are found on the surface.
