10. THE CHOCOLATE HILLS, BOHOL
PHILIPINES

Chocolate Hills |
The
Chocolate Hills are probably Bohol's most famous tourist attraction. They look
like giant mole hills, or as some say, women's breasts, and remind us of the
hills in a small child's drawing. Most people who first see pictures of this
landscape can hardly believe that these hills are not a man-made artifact.
However, this idea is quickly abandoned, as the effort would surely surpass the
construction of the pyramids in Egypt. The chocolate hills consist of are no
less than 1268 hills (some claim this to be the exact number). They are very
uniform in shape and mostly between 30 and 50 meters high. They are covered
with grass, which, at the end of the dry season, turns chocolate brown. From
this color, the hills derive their name. At other times, the hills are green,
and the association may be a bit difficult to make.
Legend
has it that the hills came into existence when two giants threw stones and sand
at each other in a fight that lasted for days. When they were finally
exhausted, they made friends and left the island, but left behind the mess they
made. For the more romantically inclined is the tale of Arogo, a young and very
strong giant who fell in love with an ordinary mortal girl called Aloya. After
she died, the giant Arogo cried bitterly. His tears then turned into hills, as
a lasting proof of his grief.
However,
up to this day, even geologists have not reached consensus on how they where
formed. The most commonly accept theory is that they are the weathered
formations of a kind of marine limestone on top of a impermeable layer of clay.
If you climb the 214 steps to the top of the observation hill near the complex,
you can read this explanation on a bronze plaque.

9. MARIANA TRENCH, PASIFIC OCEAN
The
Mariana Trench is located in the Pacific Ocean, just east of the 14
Mariana Islands (11"21' North latitude and 142" 12' East longitude )
near Japan. As you probably already know, it is the deepest part of
the earth's oceans, and the deepest location of the earth itself. It was
created by ocean-to-ocean subduction, a phenomena in which a plate topped by
oceanic crust is subducted beneath another plate topped by oceanic crust. The
deepest part of the Mariana Trench is the Challenger Deep, so named after the
exploratory vessel HMS Challenger II; a fishing boat converted into a sea lab
by Swiss scientist Jacques Piccard.
On
this site, you will find information on the main characteristics of the
Mariana Trench, its exploration, and its ecosystem. The Biology section of
the site covers the fish and various (organisms and microorganisms) of the
deep, what makes these creatures unique, and the fascinating ways in which they
live and survive. The Oceanography section explores the data
pertaining to the Mariana Trench and other deep sea formations.The Exploration
section relates some of the events pertaining to the first survey of the MT,
and the history of deep sea exploration.
We
have also included a section on the Mariana Arc, from an article published
by NOAA (National Oceanic and Atmospheric Administration) Magazine
Online. In addition to this, we also added a nautical measurement
conversion table, so that you mayIn closing we have added two supplemental
sections so that you may continue your research into the fascinating world of
the deep. Whether you are seeking answers to questions about the Mariana
Trench, or are simply interested in Marine Biology, Oceanography, or related
subjects, we hope our site will help you better understand the mysteries of the
ocean floor.
8. PAMUKKALE SPRING, TURKEY
The
hot springs of Pamukkale can be found trickling down the white cliffs of
Pamukkale in southern Turkey. The cliffs cascade downward in a widening series
of steps from a plateau more than 100m (300ft) high on Cal Da?i mountain. Water
constantly bubbles up from thermal springs under the plateau and emerges into
the air at around 38°C (98.5°F). As it journeys underground to the surface,
this warm water passes through beds of limestone, dissolving calcium carbonate
from the rock.
