“Rivers are the arteries of our planet; they are lifelines in the truest sense.”
– Mark Angelo
World Rivers Day is celebrated every year on the last Saturday of September. “World Rivers Day is a celebration of the world’s waterways. It highlights the many values of rivers and strives to increase public awareness and encourages the improved stewardship of rivers around the world.”
How Rivers are Formed
Mountains and hills tend to slow rain clouds down, squeezing the water from them. These high points usually get more rainfall than the surrounding areas. When rain falls, it has to go somewhere. Gravity causes it to run down the hills. As it runs down the hills and onto the surrounding area, it gathers in an area called a watershed, which is a valley with lots of little streams. The little streams run together to make rivers. Small rivers join to make larger rivers. Finally, a river runs all the way to the ocean or into lakes. Clouds over the ocean and lakes collect water. The water moves onto land and is dumped as rain. The process starts all over again.
