What do Subsidence and sinkholes do?
a subsidence sink hole they are in common with two other types of sinkholes called solution and collapse sinkholes they have in common thick dirt
What are the differences between subsidence sinkholes and collapse sinkholes?
subsidence sinkholes are different from collapse sinkholes in two ways . first,subsidence sinkholes ocer when there is almost no overburn,or material,above the limestone. collapse sinkholes happen when there is thick overburn. secondly, subsidence sinkholes occur slowly, over time, while collapse foms quckly beacause of human activity , such as well drilling.
Is subsidence caused by flooding caves yes or no?
