1. Rainbow eucalyptus trees
Eucalyptus deglupta, commonly known as the rainbow eucalyptus, is an ornamental tree cultivated in tropical and subtropical climates. The phenomenon is caused by patches of bark peeling off at various times, with different colors representing different ages. A newly shed outer bark reveals bright greens which darken over time into blues and purples and then orange and red tones.
4. Confluence of two rivers in Geneva, Switzerland
The river on the left is the Rhone, which is just exiting Lake Lehman. The river on the right is the Arve, which receives water from glaciers in the Chamonix valley. The Arve has a much higher level of silt, which accounts for the contrast.
5. Striped icebergs
Striped icebergs form when iceberg layers melt and refreeze quickly; green stripes are created by the freezing of krill and algae in the water. Brown, yellow and black striped can be created by sediment collected by the ice as it moved down a hillside towards the sea.
7. Spotted Lake, British Columbia, Canada
Most of the water in the so-called “spotted lake” evaporates over the summer, leaving behind all the minerals. The spots are made mainly of magnesium sulfate, which crystallizes in the summer. In the summer only the minerals in the lake remain, and they harden to form natural “walkways” around and between the spots.
