d) BU – (TLA-PCA)
Answer: a [Reason:] The total land area of a city (TLA) which is available for expansion is found out by deducting the total area of protected/conservation areas (PCA) and the existing built-up areas (BU). All these are taken in hectares.
4. Urbanisation and occupation of river banks and flood plains leads to:
a) Periodic exposure to inundation
b) Greater flow velocity
c) High run off
d) Increased soil erosion
Answer: a [Reason:] The population of town on river banks are periodically exposed to inundation from the rivers. Then slowly these extensions increase as there is less space for water to flow. Removal of natural vegetation leads to the other 3 options.
