Final answer:

Step-by-step explanation:
Punjab: The Land of Five Rivers
The region known as Punjab translates to "(Land of) Five Rivers" and refers to the five major tributaries of the Indus River. These rivers play a significant role in the regional geography of South Asia, traversing the border between India and Pakistan with headwaters in the contested area of Kashmir.
The Indus Valley Civilization was one of the great civilizations of the Bronze Age, existing from approximately 3300 BCE to 1700 BCE. Flourishing in the fertile plains created by the annual flooding of the Indus, it boasted highly developed cities, such as Harappa and Mohenjo-Daro, and advanced urban planning.
Today, the Indus River continues to be a lifeline for the people of Pakistan and India. The summer monsoon brings much-needed rain to the region, which is essential for replenishing the water systems and supporting agriculture. However, geopolitical tensions sometimes arise, such as those related to water sharing between India and Pakistan, especially in the context of the ongoing Kashmir conflict.
