b) Describe carbonation as a process of Chemical weathering

The rain falls on jointed limestone rocks
The percolating rain water reacts with limestone rock to form calcium bicarbonate (Ca(HCO3)2).

KCSE Geography Paper 1 2009 Section B Question 10.

The diagram below represents underground features in a limestone area. Use it to answer question (a)

The diagram below represents underground features in a limestone area. Use it to answer question (a) (a) (i) Name the features marked X, V and W (ii) Describe how the feature marked Y is formed (b) (i) What is an artesian basin?

(a) (i) Name the features marked X, V and W

X-Stalactite
V-Stalagmite
W-Cave

(ii) Describe how the feature marked Y is formed

Solution of solution carbonate trickles down slowly through the roof of a cave/ cavern
Solution droplets hang on the roof of the cave
Water evaporates and calcium carbonate it is precipitated
The precipitated calcium carbonate gradually builds downwards over a period of time as the solution continues to drip from the roof. This forms a stalactite
The solution splashes on the floor and water evaporates
The calcium carbonate in it precipitates and gradually builds upwards to form a stalagmite.
Over time, the stalactite and the stalagmite join to form a pillar/ column
