Step 1: Understanding the map.
The map represents the geographical divisions of the state of Andhra Pradesh. The state is traditionally divided into three major regions based on geographical, cultural, and economic characteristics.
Step 2: Telangana region.
The north-western part of the map represents the Telangana region. This region consists of districts that lie on the Deccan Plateau and is known for dry farming, mineral resources, and river basins of the Godavari and Krishna.
Step 3: Coastal Andhra region.
The eastern part of the map along the Bay of Bengal represents the Coastal Andhra region. This area is highly fertile because of the deltas of the Godavari and Krishna rivers. Agriculture, especially rice cultivation, is very prominent here.
Step 4: Rayalaseema region.
The southern part of the map represents the Rayalaseema region. It consists of districts located in the southern interior part of Andhra Pradesh. This region is comparatively dry and depends on irrigation projects for agriculture.
Step 5: Conclusion.
Thus, the three major regions shown in the map of Andhra Pradesh are Telangana, Coastal Andhra, and Rayalaseema.
