The Indus Valley had a very diverse environment. Some parts of the environment where Dessert, Mountain, Highland, Rainfall. They had to deal with unpredictable floods, droughts, monsoons, earthquakes. A monsoons is when there is a rainy season. But there are places where it is moist and humid. There are big forests with tigers, rhinos, elephants, sounds like a pretty scary place. In the western part of the Indus Valley there are sheep, goat, cattle, and wild ibex. The Thar Desert today is covered in sand, but there has been vegetation there in the past. The river was a great source of food too. The snow up in the mountains started to melt so there would be water and thats how it would flood, there was also rich soil that came from that soil. The Indus River begins in the Himalaya Mountains, and flows nearly 3,000 kilometres to the Arabian Sea. It's the biggest river in Pakistan
