• Plateaus of Tamil Nadu can be grouped into two as Coimbatore plateau and Madurai plateau. 

The Western Ghats and Eastern Ghats meet at the Nilgiri Hills.

• At least 24 of the Nilgiri mountains' peaks are above 2,000 metres (6,600 ft), the highest peak being Doddabetta, at 2,637 metres (8,652 ft).

There are two types of plains in Tamil Nadu which are coastal plains and river plains. The coastal plains of Tamil Nadu extent from Publicat lake in the north to Kanyakumari  in the South, to a length of 1,000km at an average elevation of 50mt. The notable beaches found here are the Marina beach and the Rameshwaram beach.

The Coastline of Tamil Nadu is located on the southeast coast of Indian Peninsula, and forms a part of Coromandel Coast of Bay of Bengal and Indian Ocean. It is 1,000 km long and is the second-longest coastline in the country after Gujarat. 

The Eastern Ghats are not continuous when compared to the Western Ghats. They are dissected into isolated hill ranges extending from northeast to southwest through the districts of Vellore, Dharmapuri and Erode.

The Eastern and Western Ghats meet at the Nilgiris plateau. Four km from this plateau, it slopes gently downwards to about 1,800 m towards Coimbatore.

The Western Ghats has mountain peaks namely Doddabetta (2637 m) and Mukuruthi (2540 m).

The Bramahal plateau in Dharmapuri district is at an elevation of 300 to 700 m which merges with the Mysore plateau in the west.

The Nilgiris plateau extends from the Nilgiris to Dharmapuri plateau or Bramahal plateau and lies to the west of Shervaroy uplands. This plateau is found with extreme abruptness on all sides.
