- The Deccan plateau belongs to the Archean system. It is made up of basalt, gneiss and schist rocks.
- Telangana is located in the Northern hemisphere.
- It is situated in South Asia.
- Physically, Telangana state is located on the Deccan Plateau. It is a part of Deccan plateau and the area where it is spread on the Deccan Plateau is called Telangana Plateau’. The general slope of the Deccan Plateau is from West to East. This plateau consists of three ranges of erosion surface. They are:
(a) Region above 600 meters from mean sea level
(b) Region from 300m- 600m above the mean sea level
(c) Region below 300m above the mean sea level
A) Region above 600 meters from mean sea level
- This erosion surface is spread mainly in the west side of the state. It lies in Hyderabad, Rangareddy,
- Medchal Malkajgiri, Vikarabad, Sangareddy, Medak, Siddipet southern region and Nagarkurnool.
- This region consists of peneplained surfaces made of rocks of archacan origin. Normally this region slopes towards the East.
- This area includes the east flowing rivers of fKrishna and Godavari.
B) Region between 300m-600m above mean seal level:
- This region lies between the highest region in the west and lowest region in the east. It is spread over the western districts of Telangana state- Vikarabad, Mahabubnagar, Nizamabad,Kamareddy and Warangal.
- The fault valleys of Godavari came into existence due to the subsidence process. Krishna and Tungabhadra valley is present at an altitude between 300 meters to 450 meters in the south.
- It is internally comnoseda Gneiss rock. This region has plenty of water resources such as lakes that support agriculture
C) Region below 300m above the mean sea level:
- This region occupies a large area in Telangana state and extends on both sides of Godavari river lt lie mainly in the erstwhile Nalgonda, Khamypam, Waranga, Karimnagar and Adilabad-districts.
- This region is also favorable for cultivation.
- Another name of Telangana is Ratnagarbha.
- The territory of Telangana looks like an Isosceles triangle. Telangana is a part of Peninsular India that was separated from Gondwana region. The 33 districts ofTelangana state are present in Deccan plateau. Many hill groups made up of granite in the shape of toes and boulders are distributed in Hyderabad, Rangareddy, Vikarabad, Medchal Malkajgiri districts.
- Region between United Rangareddy and Mahabubnagar districts- Peneplains formed with basalt lava. Nizamabad, Kamareddy, Medak, Sangareddy, Siddipet districts- gneiss and granite rocks.
- Nirmal, Mancherial, Jagtial, Peddapalli, Jayashankar Bhupalapally, Mulugu, Bhadradri Kothagudem districts- As these districts are in Godavari river valley, coal deposits were formed with ancient Gondwana rocks. Gondwana rocks are present in Telangana in Godavari basin.
- Telangana region is located at an altitude of480m-600m above sea level.
- Hyderabad lies at an altitude of 600 m above sea level
- The region between Krishna and Tungabhadra river valleys lies at an altitude of 300m-450m.
- The region between Bhima and Godavari rivers (The region encompassed by Hyderabad, Khammmam and Warangal) lies at an altitude of 730 m. The Eastern ghats on the eastern side and Western ghats of the southern side of Deccan plateau enter the Telangana region. Western ghats are also known as Sahyadri or Satnala range. The Western Ghats of Sahyadri range detached from Ajantha range entered Adilabad district from South East of Telangana region. The Eastern ghats spread to Telangana from Mahabubnagar in the form of Eastern hills. The Eastern ghats in Telangana form several discontinuous ranges of low hills which are called with different names in different regions.
- The highest peak in Eastern ghats in Telangana is Lakshmidevipalli hill. This is located in Siddipet district.
- The highest range in Western ghats in Telangana (Nirmal district)is Mahabub Ghat.
- The highest point in the Deccan plateau isSolamile (Jangaon).
- Telangana region can be divided into 3 regions based on topography.
