Blue hole

 Every one knows about black holes found in the space.


Now I am writing about Blue Hole.


What is a blue hole ??


A blue hole is a vertical cave typically carved out of eroded limestone that opens onto ocean floor with a rounded mouth.



How blue holes form  ??


Blue holes are formed due to the flooding and erosion during the last ice age  !!!!


The waters there are cold, slightly acidic and completely devoid of oxygen because of lack of photosynthesis.


Blue holes are the ocean synkhole pools. 


The deepest blue hole is nearly the length of eiffel tower, deep under!!!!
