When limestone is weathered via carbonation by acidic water and ERODED by that water causing the land above to collapse.

|
A pile of sediment and rocks that has been eroded then DEPOSITED by a glacier (ICE)

|
the sudden movement of rock and soil down a slope caused by GRAVITY, heavy rains (WATER), cutting down trees, construction on steep slopes, and/or earthquakes.

Pollution (sulfuric acid) from factories dissolves in precipitation; a cause of CHEMICAL weathering when the acid eats away at rocks and buildings.

Detailed explanation-1: -A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone.
Detailed explanation-2: -Sinkholes are formed when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the voids. Drought, along with resulting high groundwater withdrawals, can make conditions favorable for sinkholes to form.
Detailed explanation-3: -sinkhole, also called sink or doline, topographic depression formed when underlying limestone bedrock is dissolved by groundwater. It is considered the most-fundamental structure of karst topography. Sinkholes vary greatly in area and depth and may be very large.
Detailed explanation-4: -Solution sinkholes are formed by local chemical weathering of the rock, where water accumulates around a fissure or joint in the rock. This may be underneath the soil or on the ground surface. The hollow that is formed is drained of water through the fissure or joint, but not before it has dissolved some of the rock.
Detailed explanation-5: -The formation of sinkholes involves natural processes of erosion or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion.
