Important Rivers Around The World

Here you will find intresting facts about rivers and how we can keep them clean!

To keep our rivers clean...
 
1. Don't throw you garbage in the water
2. Don't dump any hazardous materials into the water
3. Recycle

Where does all that water go?
All of the water that is discharged into the Atlantic Ocean is actually only about 1/3rd of the water that falls into the Amazon basin as rain. Where does the other 2/3rds go? Up to half of the rainfall in some areas may never reach the ground, being intercepted by the forest and re-evaporated into the atmosphere. Additional evaporation occurs from ground and river surfaces, or is released into the atmosphere by evapo-transpiration from plant leaves. All of this evaporated moisture re-enters the water cycling system of the Amazon, and a given molecule of water may be "re-cycled" many times between the time that it is evaporated from the surface of the Atlantic Ocean and carried by the prevailing westerly winds into the Amazon basin, to the time that it is carried back to the ocean by the Amazon River.

About the Amazon
 

Average rainfall across the whole Amazon basin is approximately 2300 mm (or 7.5 feet) annually. In some areas of the northwest portion of the Amazon basin, yearly rainfall can exceed 6000 mm (19.7 feet)!

DID YOU KNOW?

The Amazon basin is home to over 2,400 known species of fish, more species than are found in the entire Atlantic Ocean! Some scientists estimate that there may be as many as 5,000 species! These range from giant air-breathing fish (Arapaima gigas) and river catfish weighing up to 600-700 lbs, to tiny tetras, electric eels, sting-rays, needlefish, fresh-water flying-fish, and knife-fish. The fish fauna of many river systems is poorly known, and new species are discovered yearly, even in the "better-known" areas!

AND...
 
The mouth of the Amazon is over 320 km wide (approximately 200 miles), and contains the worlds largest freshwater island, Marajó Island, with an area of 48,000 km2.
