Believe it or not, this is planet Earth!


                                                                Snow Roller

Rare weather phenomena, in which large rolls of snow form naturally. It is formed by wind blown in the snow that goes rolling and collecting more and more snow along the path. Unlike the snowballs created by humans, these circles of snowflakes have a cylindrical shape, and are usually hollow in the center. This is because the inner layers are the first to form when the wind is blown.


                                                           Mammatus Clouds

Mammatus, mamma or mammatocumulus is a meteorological term that refers to the pattern of clouds similar to "bags". These clouds are mainly made up of ice and can extend for thousands of miles in all directions. This training can be seen from 10 minutes to an hour. This formation of clouds is associated with strong storms.


                                                                  Ice flower


This ice structure is formed in strong frost below zero, around the plants, where the plant in turn, is hotter than the ambient temperature. In a process very similar to sweating, the water of the "sweat" of the plants is frozen in fragile layers of ice.


                                                                     Ice Stalactite


This type of formation usually happens at the poles of the Earth where sea salt water freezes. The sea saltwater mixture tends to be denser on the surface, causing the frozen water above to slowly sink and create a pockmarked appearance with stalactites (formations that grow from top to bottom).


                                               Cloud Perforated, Clouds Falling Illusion

Circular or elliptical shape that can appear in Cirrocumulus or Altocumulus cloud formations. These holes arise when the temperature of the water particles are below freezing, but they have not frozen because of the lack of ice nucleation. As a chain effect, and generally circular in shape, the droplets around the ice crystals are evaporated, creating this dropping effect in the center.




                                                                           Basalt columns
Unique format. The basalt emerges cracked. We can say that this is a result of the cooled lava flows.


                                                                      Penitents
Ice structures formed in areas of high altitude and with low humidity, as in the glaciers of the Andes. In these formations the exposure of the solar rays are extremely strong, and they evaporate the ice without forming liquids, creating the sharp tips.
