What were the natural conditions in ancient India?

Ancient India covered vast territories, so the climatic conditions there were very diverse. In the Indus Valley, the climate was drier, and moisture mainly came from the river itself, which influenced the entire region. In the Ganges valley, the climate was very humid, monsoon. There was a dry desert zone between these rivers. The weather was very humid in South India.

Savannas and woodlands grew in the Indus Valley, and tropical rainforests in the southern part and in the Ganges Valley, as they do today.
