Phenomenal Wonders Of The Natural World
WebEcoist and Environmental Oddities
When a thick lava flow cools, it contracts vertically
but cracks perpendicular to its directional flow with remarkable geometric regularity
– in most cases forming a regular grid of remarkable hexagonal extrusions
that almost appear to be made by man.
They can be hundreds of feet deep
and while divers are able to explore some of them
they are largely devoid of oxygen that would support sea life
due to poor water circulation – leaving them eerily empty.
While many see these apparently perfect ice circles
as worthy of conspiracy theorizing,
scientists generally accept that they are formed
by eddies in the water that spin a sizable piece of ice in a circular motion.
Fire whirls can be spawned by other natural events
such as earthquakes and thunderstorms,
and can be incredibly dangerous,
in some cases spinning well out of the zone of a fire itself
to cause devastation and death in a radius not even reached by heat or flame.
The bottommost image above is true to the hues of the moon
but has enhanced colors to more clearly show the differences in shade
that illustrate the mixed topography and minerology
that tell the story of the moon’s surface.
