Answer to Question 1

In order for limestone to develop into karst topography, it must contain 80 or more of calcium carbonate, it must have a complex patterns of joints and an aerated zone; and vegetation must be present. Common features of karst topography include sink holes (dolines), karst valleys; cockpits and cones; caves and caverns; and (within caves and caverns) the varied spleothems.

Answer to Question 2

Hydration involves little chemical change in the rock and doesn't form new chemical compounds. However, it does involve a change in the structure of the rock. Hydrolysis is the decomposition of a chemical compound by reaction with water. Hydrolysis chemically breaks down a mineral, thereby producing a different mineral through a chemical reaction.
