Amazon River
The world’s mightiest river is the Amazon, in South America. Only the Nile, in Aftrica, is longer than the Amazon.
But the Amazon carriers more water than any other river, its flow is greater than that of the Mississippi, the Nile and the Yangtze rivers combined.
The Amazon begins high in the Andes Mountains and empties into the Atlantic Ocean, 4,000 miles away. It sweeps across Brazil, gathering water from numerous streams.
At many places the Amazon is too wise to see across. In many places it is over 350 feet deep.
No river holds more kinds of fish. One of these is the man-eating piranha fish. The electrical also lives there, and alligators, dolphins and giant turtles are common.
The river was named after the Amazons, the women warriors of Greek mythology. An early Spanish explorer gave the river its name after a battle with some Indians in which the women of the tribe fought alongside the men.

Clouds
Pluffy dark clouds and fluffy white clouds—all clouds are made of the same thing. They are made mostly of tiny droplets of water drifting about on currents of air. Water to make clouds comes from oceans, lakes and streams.
Everywhere water is continually evaporating into the air in the form of an invisible gas called water vapor. Often the water vapor is carried upward by currents of warm, rising air.
As the moist air rises it cools. As it cools, some of the water vapor condenses, or changes back to liquid water, in the form of tiny droplets, like the ones you moist breath makes when it hits the cold air on a winter day.
Many millions of these droplets, too small to fall, cluster together and make up the clouds in the sky.
Sometimes a cloud looks fluffy and white because the sun is shining through it. Storm clouds may look dark and gray because they are too thick to let much sunlight through.

Good Water Deal, Ground Water, More Water, Ordinary Spring, Ordinary Well, Rain Water, Some Lower Point
Artesian Wells, Clay, Fountain, Gravity, Great Pressure, Ground, Ground like Fountain, Imprisoned Water, Lakes, Layers of Rocks, Lower Point, Melted Snow, Ocean, Pump, Rain, Spring, Streams, Underground Water, Water, Water Pressure
An artesian well needs no pump. It spurts out of the ground like fountain. There is more water in the world than in our oceans, lakes and streams. A good deal of water can be found beneath the ground. Springs are formed when water from rain and melted snow seeps deep into the ground. The underground water can fill the bottom of a well, or it can bubble out of the ground as a spring.
An artesian well is quite different from the ordinary well or spring. In an ordinary well, the water must be pumped out with a pump. An ordinary spring occurs when the underground water seeps downhill from the pull of gravity and bubbles out of the ground at some lower point. It is only where the water gets trapped between layers of rocks or clay that artesian wells are possible.
Ask the imprisoned water collects between the layers of rock, the weight of the water may become so great that it builds up a great pressure. When a well is dug, or if it finds a natural opening, the water gushes out without the aid of a pump or gravity.

Lights
The Northern Lights, or Aurora Borealis, are the magnificent display of colored lights that occurs near the earth’s north Magnetic pole. If you live far enough north, you may have seen the magnificent display of glowing, flickering colored lights high in the clear night sky. The northern lights are one of nature’s most dazzling shows. They begin as tiny flickering lights. They grow and grow until they seem to light up the whole sky. Sometimes they look like a great, fiery curtain with flames of red, orange, green and blue.
At other times they may flash here and there like giant search-lights, or the brilliant rays may spread upward in the shape of a gigantic fan. The northern lights are caused by the sun. On the sun there are often great storms. We call them sunsports. Streams of tiny electric particles shoot out toward the earth.
When these electric particles reach the rare gases high above the earth’s surface, they cause them to glow brightly, very much like a neon sign glow. People who live near the South Pole see glowing lights, too! These are the aurora australis, or southern lights. -Dick Rogers
