WEATHERING
AROUND Me
Weathering is a term which describes the general process by which
rocks are broken down at the Earth’s surface into such things as
sediments, clays, soils and substances that are dissolved in water.
Gravel from my Backyard – most of the rocks here have a smooth
texture and have jagged edges because of abrasion from water. The
process of erosion brought them here.
Odloman Cave in Negros Oriental –
is the 2nd longest cave system in the
Philippines. It was formed through
the dissolution of limestone through
carbonic acid from rainwater over
the course of millions of years.
Callao Cave in Peñablanca, Cagayan
– a popular limestone cave in the
Philippines. It is formed when carbonic
acid seeps into the limestone,
dissolving it and after a million years,
creates beautiful limestone caves like
this.
Boracay Beach in Malay, Aklan – the
fine-grained sand is formed from the
breaking down of rocks by water into
smaller particles. The sand mostly
contains iron which produces a
yellowish color when oxidized.
Pinagbuyutan Island in El Nido, Palawan the white sand from this beach is formed
through the weathering of rocks and minerals
such as calcium carbonate and limestone.
Kapurpurawan Rock Formation in Burgos,
Ilocos Norte – a famous tourist attraction in
Ilocos Norte that is composed of white
limestones and was continuously sculpted by
the ocean and the wind for millenia.
Underground River in Puerto Princesa,
Palawan – it is considered to be a World
Heritage Site by UNESCO. It was formed
when carbonic acid seeps into the
limestone, dissolving it slowly and forming
networks of undeground caves.
Cape San Agustin Rock Formation in
Davao Oriental – it was shaped to its
current appearance through the process
of weathering by waves and strong
winds from storms.
Biri Rock Formation in Biri, Northern
Samar – yet another majestic rock formation
that was weathered by the waves and the
wind for thousands of years to create its
interesting shape today.
