What is the main type of rock that made up. the region? Account for the formation of the charomatic
features A and B. Name the features you would expect to see underground at B
ANSWER :
a. Name of the rock.
The area. is mainly made up of limestone . Formation of the characteristic features. A- Spring.
It is a vauelusian spring formed where limestone overlies anda impermeable rock layer: such as clay or shale. The joints of the overlying.limestone are easily opened up.

It is partly due to
its previous nature
and partly its

alightly acidic as carbon dioxide in the air has been dissolved, acts actively upon the rock, Joints are
therefore widened by (solution and caves and underground channels are thus developed down to the imper- meable base of the formation. The latter bolds up the water allows it to drain out as a spring on the cacarp slope.
