What are the three main physical regions of Andhra Pradesh?

Andhra Pradesh is divided into three primary physiographic regions:

• The Coastal Plain: Located to the east, this region extends from the Bay of Bengal to the mountain ranges. It is a fertile area, particularly in its central portion where the Godavari and Krishna rivers form extensive deltas.1
• The Eastern Ghats: These mountain ranges form the western flank of the coastal plain. They are not a continuous chain but rather a series of discontinuous hill masses that run parallel to the coast.12
• The Plateau: Situated in the southwestern part of the state to the west of the Eastern Ghats, this region is part of the Deccan plateau. Often referred to as Rayalaseema, it is characterized by graded valleys, isolated hills, and red sandy soil.1
