Step-by-step explanation:
Ancient Egypt, much like modern-day Egypt, relies on the Nile rivers irrigation to help keep the soil around the river fertile and good for arable farming. It is also home to the Valley of Kings and the pyramids were also built along the Nile.
The ancient Indus Valley civilization is a vast area with the large Indus river flowing through it. This river begins in the Hindu Kush and flows to the Arabian Sea. The river offered good irrigation to grow grains.
One of ancient China’s most valuable exports was silk. They kept the silkworms and people would travel great distances to obtain the silk. This trade route was known as the silk road. This was difficult as China has the Himalayas to its South, the Gobi desert to cross to Europe and an ocean along its Eastern border.
