The Palghat Gap (or Palakkad Gap), a region about $30\:km$ wide in the southern part of the Western Ghats in India, is lower than the hilly terrain to its north and south. The exact reasons for the formation of this gap are not clear. It results in the neighbouring regions of Tamil Nadu getting more rainfall from the South West monsoon and the neighbouring regions of Kerala having higher summer temperatures.
What can be inferred from this passage?
- The Palghat gap is caused by high rainfall and high temperatures in southern Tamil Nadu and Kerala
- The regions in Tamil Nadu and Kerala that are near the Palghat Gap are low-lying
- The low terrain of the Palghat Gap has a significant impact on weather patterns in neighbouring parts of Tamil Nadu and Kerala
- Higher summer temperatures result in higher rainfall near the Palghat Gap area
