A Wonderleaf question

What is the longest river in the world?

What is the longest river in the world?

a real page from the book

Most reference books still name Africa’s Nile as Earth’s longest river, running about 4,132 miles to the Mediterranean Sea. Some scientists argue the Amazon is a little longer if you count its farthest mountain stream as the start, so the answer depends on the measuring rule.

That is the part kids often love: rivers are not tidy lines on a map. They grow from springs, rain, snowmelt, and side streams. The Amazon may lose the length contest in many books, but it carries more water than any other river.
