Western Ghats

The Western Ghats, also known as the Sahyadri Mountains, are a mountain range along the western coast of India. They are older than the Eastern Ghats and have been formed over 150 million years ago. The Western Ghats are considered one of the eight hottest hotspots of biological diversity in the world.

Eastern Ghats

The Eastern Ghats are a discontinuous range of mountains along India's eastern coast. They are younger than the Western Ghats and were formed around 20 million years ago. The Eastern Ghats are not as high or continuous as the Western Ghats, but they still play a significant role in the region's ecology and biodiversity.

Comparison

- The Western Ghats are older than the Eastern Ghats, with a difference of approximately 130 million years in their formation.
- The Western Ghats are taller and more continuous than the Eastern Ghats, which are lower and fragmented.
- Both mountain ranges are important for their ecological significance, providing habitats for a diverse range of flora and fauna.
- The Western Ghats are known for their high levels of endemism, with many species found only in this region.
- The Eastern Ghats, although not as well-known as the Western Ghats, also have a rich biodiversity and are home to several endemic species.

In conclusion, the Western Ghats are older and more prominent than the Eastern Ghats, but both mountain ranges are vital for the conservation of biodiversity in India.
