Explanation / Answer

The percentage of pore spaces in a rock that can contain or hold water is called porosity. Porosity is pore spaces or void fraction which is measured by the void spaces in a material, and is a fraction of the volume of voids over the total volume.

Karst topography is characterized by disappearing streams and rivers. It is formed when lower support has been removed by chemical weathering through which stream and river disappear.

Stalagmites can be found growing up from the floor of a cave. Stalagmites may be composed of lava, minerals, mud, peat, pitch, sand, sinter and amberat.
