BEUTY OF NATURE

 A rainbow is an arc of color in the sky that can be seen when the sun shines through falling rain. The pattern of colors, called a spectrum, starts with red on the outside and changes through orange, yellow, green, blue, indigo, and violet on the inside. Sometimes a second, larger, dimmer rainbow is seen.

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun.

  A  river  is a natural flowing  watercourse , usually  freshwater , flowing towards an  ocean ,  sea ,  lake  or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as  stream , creek, brook, rivulet, and  rill . There are no official definitions for the generic term river as applied to  geographic features , [1]  although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, " burn " in Scotland and northeast England, and "beck" in northern England.
