Explanation:

The Chota Nagpur Plateau consists of three steps. The highest step is in the western part of the plateau, where pats, as a plateau is locally called, are 910 to 1,070 metres (3,000 to 3,500 ft) above sea level. The highest point is 1,164 metres (3,819 ft). The next part contains larger portions of the old Ranchi and Hazaribagh districts and some parts of old Palamu district, before these were broken up into smaller administrative units. The general height is 610 metres (2,000 ft). The topography in undulating with prominent gneissic hills, often dome-like in outline. The lowest step of the plateau is at an average level of around 300 metres (1,000 ft). It covers the old Manbhum and Singhbhum districts. High hills are a striking part of this section - Parasnath Hills rise to a height of 1,370 metres (4,480 ft) and Dalma Hills to 1,038 metres (3,407 ft). The large plateau is subdivided into several small plateaux or sub plateaux.
