The Indian subcontinent has some really important geographic features. First, there are the mighty Himalayas, which are the tallest mountains in the world and separate India from Tibet. The Ganges River is a major river that is sacred to many people and flows across northern India. There are also the Thar Desert, which is hot and dry, and the fertile plains of the Indo-Gangetic region, where lots of crops are grown.
As for the climate, it varies a lot! Most of India has a tropical climate, which means it's warm and can be humid. There are four main seasons: a hot summer, a rainy monsoon season, a cooler winter, and a spring season. The monsoon brings heavy rain to many areas, especially from June to September, making it really important for farming.
