Wonders Of The Nature !!!
Wonders Of The Nature
WebEcoist and Environmental Oddities
1. Sailing Stones
have been a center of scientific controversy for decades.
Rocks weighing up to hundreds of pounds have been known
Rocks weighing up to hundreds of pounds have been known
to move up to hundreds of yards at a time.
Some scientists have proposed that a combination of
Some scientists have proposed that a combination of
strong winds and surface ice account for these movements.
However, this theory does not explain evidence of different rocks
However, this theory does not explain evidence of different rocks
starting side by side and moving at different rates and in disparate directions.
Moreover, the physics calculations do not fully support this theory
Moreover, the physics calculations do not fully support this theory
as wind speeds of hundreds of miles per hour
would be needed to move some of the stones.
2. Columnar Basalt
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.
One of the most famous such examples is the
One of the most famous such examples is the
Giants Causeway on the coast of Ireland (shown above),
though the largest and most widely recognized
would be Devils Tower in Wyoming .
Basalt also forms different but equally fascinating ways
Basalt also forms different but equally fascinating ways
when eruptions are exposed to air or water.
3. Blue Holes
that get their name from the dark and foreboding blue tone they exhibit
when viewed from above in relationship to surrounding waters.
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.
Some blue holes, however, contain ancient fossil remains

Some blue holes, however, contain ancient fossil remains
that have been discovered, preserved in their depths.
