1. Northern Karst

2. Northern Karts Rocky Region located between the interior mountain ranges and the northern coastal plain. Its is made up of limestone https://www.youtube.com/watch?v=1tYY6hA2rPwhttps://www.youtube.com/watch?v=1tYY6hA2rPw Over time rain and rivers eroded parts of the northern Karst limestone creating pointy hills (similar shape to egg carton) called Mogotes. Caves Formed by the movement of water through underground rocks. Water dissolve slowly the limestone creating tunnels (vaults). https://www.youtube.com/watch?v=3f5EjdrvX0g

3. Caves formations Sometimes, water wears down the limestone's in the caves This causes rocks to fall down and form sinkholes. Water drips through the roof of these caves and creates cone-shaped formation that hang from the room known as stalactites. https://www.youtube.com/watch?v=Y1B2tEqazPI Stalagmites are also shaped as a cone but they grow upwards. When stalactites and stalagmites run into each other form columns.
