Answer 2

Answer:

By about 2500 BC, four Bronze Age civilizations emerged. These were:

i) the Harappan civilisation in the northern and western parts of India and Pakistan;

ii) the Mesopotamian civilisation on the banks of the river Euphrates and Tigris in modern Iraq;

iii) the Chinese civilisation in the valley of Hwang-ho and Yangtze rivers;

iv) the Egyptian civilization on the banks of the Nile river in Egypt

The Bronze Age is a prehistoric period that was characterized by the use of bronze. The Bronze Age marked the first time humans started to work with metal. Bronze tools and weapons soon replaced earlier stone versions.
