Rivers begin as fast-flowing streams high up on mountainsides. Some streams bubble up from underground. Others flow from lakes or trickle from the tips of icy glaciers when they start to melt. The start of a river is called its source.
Amazing! The world’s shortest river is D River in Oregon, USA. It’s a titchy 37 metres long. Is the Nile or the Amazon the longest river?
The Nile in Egypt is the longest river on Earth. It flows for 6,695 kilometres. The Amazon in South America is just 295 kilometres shorter.
How high are waterfalls?
The highest waterfall in the world is Angel Falls in Venezuela. It plunges 979 metres down the side of a mountain. Angel Falls are 20 times higher than the famous Niagara Falls in North America.
Is it true? Rivers flow into the sea.
Yes. Most rivers flow into the sea at their deltas. But some rivers flow into lakes and a few flow into deserts.
