Frost flowers mainly form over water or humid surfaces. When the cold humid air above a water surface becomes saturated, frost starts to form on any imperfections on the water surface. These imperfections are the rooting for these “flowers,” and the moisture from the air helps them rise.
It grows only on humid winter nights and usually melts in the day. Ice crystals form on rotten wood that has a presence of mycelium, which are the roots of a fungus that lives on rotting wood.
Pyura chilensis, also known in Spanish as piure, this “rock” is actually a saclike marine invertebrate filter feeder (aka sea squirt). These filter feeders have a characteristically bloodred hue to their insides which gave them their nickname of “bleeding rocks.” Locally, they are eaten raw like an oyster or cooked with salad and rice.
A colorless rainbow occurs in the same fashion as other rainbows, with sunlight passing through water droplets. But in this case, it happens when fog is forming. The droplets in the fog are much smaller. As a result, most color is lost while passing through them.
Well, here we have Eucalyptus deglupta, commonly known as the rainbow eucalyptus. Native to the Philippines and other tropical areas, it can grow up to 76 meters (250 ft).
This phenomenon is easier to observe at sundown and lasts only a second or two. That’s why this event is usually referred to as a flash. The atmosphere works as a kind of prism, breaking the light from the Sun into separate colors.
In Indonesia, the Kawah Ijen crater on the island of Java appears to spout blue lava instead of the traditional yellow and orange tones we are all used to. The most interesting part is the confusion this produces. The lava is not inherently blue. Instead, this event is produced by the combustion of a high concentration of sulfur in the area of the volcano. When sulfur ignites, it burns with a blue flame. So when the high concentration of sulfur comes in contact with the lava, the lava appears to turn blue.
The bloom happens between September and November and only in years when rainfall is unusually high. It is known locally as desierto florido (“the flowering desert”).
The Lake Natron has a high pH, making it caustic enough to burn the skin and eyes of unadapted animals. However, the lake has a nurturing ecosystem of animals that have adapted to life in this harsh environment.
This happens because the Atlantic Ocean tides meet the mouth of the Amazon River. The sound it produces can be heard 30 minutes in advance of its arrival. Since the wave contains debris from the river, which can be entire trees, it’s also the most dangerous wave to ride.
