The Western Ghats also hold significant cultural, spiritual, and historical importance, having been inhabited by various indigenous communities for thousands of years.
Location
The Western Ghats are a mountain range located on the western coast of India, running parallel to the Arabian Sea. The range stretches from the state of Gujarat in the north, through Maharashtra, Goa, Karnataka, and Kerala, and ends at the southern tip of Tamil Nadu. The range covers an area of approximately 140,000 square kilometers, spanning a distance of around 1,600 kilometers. The Western Ghats are an important ecological and cultural region of India, and are recognized as a UNESCO World Heritage site.
Terrain and Topography
The Western Ghats are a rugged mountain range that runs parallel to the western coast of India. The terrain and topography of the Western Ghats are diverse and varied, featuring high peaks, deep valleys, plateaus, and rolling hills. The range comprises several distinct regions, each with its own unique geography.
The northern part of the Western Ghats is characterized by high peaks and steep slopes. The highest peak in the Western Ghats, Anamudi, is located in this region, reaching a height of 2,695 meters above sea level. The central region of the Western Ghats consists of a series of plateaus and rolling hills, with elevations ranging from 500 to 1,500 meters above sea level.

Geology
The Western Ghats, also known as the Sahyadri Mountains, is a mountain range that runs parallel to the western coast of India. The range is around 1,600 km long and covers an area of approximately 140,000 square kilometers. The geology of the Western Ghats is highly diverse, consisting of sedimentary, metamorphic, and igneous rocks. The Western Ghats are primarily composed of ancient rocks that were formed around 1500 to 2500 million years ago during the Archean and Proterozoic eras. The region is dominated by granites, gneisses, and schists, which are highly metamorphosed and deformed. These rocks were formed due to the high temperature and pressure conditions during the Precambrian period.
The sedimentary rocks of the Western Ghats include sandstones, shales, and limestones, which were formed during the Paleozoic and Mesozoic eras. These rocks are found in the valleys and lowlands of the mountain range. The Western Ghats also have extensive volcanic activity, which has led to the formation of various volcanic rocks such as basalt, andesite, and rhyolite. The Deccan Traps, which are one of the largest volcanic features on Earth, cover large parts of the Western Ghats.
The Western Ghats are also known for their rich mineral resources, including iron, manganese, bauxite, and gold. Overall, the geology of the Western Ghats is highly complex and diverse, making it an important region for geological research and exploration.
Climate
The Western Ghats have a tropical climate, characterized by high temperatures and high humidity throughout the year. However, due to the range’s elevation and varied topography, the climate can vary significantly depending on the location within the mountain range. The northern and central regions of the Western Ghats receive heavy rainfall during the monsoon season from June to September, with an average annual rainfall of around 2,500 to 5,000 millimeters. The heavy rainfall supports lush tropical rainforests and dense vegetation in these regions. The southern part of the range receives less rainfall, with an average of around 1,000 to 2,500 millimeters of rain per year.
During the winter months, from November to February, the Western Ghats experience cooler temperatures, with average temperatures ranging from 15 to 25 degrees Celsius. The summer months, from March to May, are hot and humid, with temperatures ranging from 25 to 35 degrees Celsius.
The climate of the Western Ghats plays a crucial role in supporting the region’s rich biodiversity, with the heavy rainfall and high humidity creating ideal conditions for the growth of tropical vegetation and providing important habitats for a diverse range of animal species.
