GEOLOGY

Detailed explanation-1: -Cave in Section – Due to the erosion caused by either running water or surface water, a cavity is formed in the rock which transforms into a cave. Sink Holes – It is one of the most common features in Karst Topography.

Detailed explanation-2: -Sinkholes, disappearing streams, and caves are all common features of karst.

Detailed explanation-3: -Features of karst landscapes include caves, springs, disappearing streams, dry valleys, and sinkholes. Acidic groundwater moves through fractures and spaces within the rock, slowly dissolving and enlarging spaces to create larger openings and connected passages.

Detailed explanation-4: -Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Detailed explanation-5: -Features such as lapiés, natural bridges, and pepino hills are characteristic of karsts. If a cave becomes large enough and the top extends close enough to the surface, the top collapses. This produces depressions called sinkholes, which are among the most characteristic features of karst topography.
