秘鲁彩虹山：大地披上七彩霓裳
In Peru, there is a strange mountain. It looks like a rainbow on the ground. People call it Vinicunca, or Rainbow Mountain. It sits high in the Andes, over 5,000 meters up.
The mountain's colors are from minerals. Minerals are natural things in the ground. Iron makes red. Copper makes green. Sulfur makes yellow. Millions of years ago, these layers formed. Rain and wind uncovered them. Now the mountain looks like a rainbow.
