The document summarizes the key geographic features and regions of the Philippines. It describes the major landforms of plains, plateaus, and mountains. It also discusses the country's coastal features like coral reefs and internal bodies of water. The 18 administrative regions of the Philippines are then outlined based on factors like landforms, location, and population density. Regional studies are important for regional development and balanced national growth.

10. An important event in geologic history which took
place some 200 million years ago. It was
characterized by a world wide mountain building
movement.
It was during this period that the outline of the
Philippines was believed to have been brought for
the first time above sea level.
This marked a period of mineralization in the
country that gave rise to the deposits of gold, silver,
and copper ores of which the diorite is the parent
rock.

13. The salient physiographic or topographic features of the
Philippines are briefly summarized as follows:
 The irregular configuration of the Archipelago and its fragmentary
character consisting of about 7 ,107 islands and islets;
 The mountainous character of the islands running on a general north to
south trend and in close proximity to the coastline;
 The great extent of the coastline reaching a total of 17,460 kilometers,
which is twice as long as that of the United States;
 Sulu Sea which lies between Palawan and Mindanao is the largest internal
body of water of the country;
 The structural plains lying between mountain systems and the narrow and
interrupted coastal plains;
 The few large rivers and many streams which are short and swift, that
descend to the sea;
 The great variety of lake that are of diverse origin of which Laguna de Bay
being the largest;
 The big number of active, dormant, and extinct volcanoes among which
Taal Volcano has the most violent eruptions;
 The presence of coral reefs fringing the shores of most of the islands, and
many islets are made up of corals; and
 The vast extent of the territorial waters within the international treaty
limits which comprises more than five times the land area.

16. The Lanao-Bukidnon plateau and the Tiruray
table land are the principal plateaus while
the Cotabato Valley and the Agusan-Davao
Lowland are the principal plains.
The coastal plains through-out Mindanao
are also suitable for agriculture and are
centers of settlements.

17. Plains, under proper climatic
conditions, provide the most favorable
sites for economic and social progress.
Plains are the lowlands of the
continents
History tells us that the cradles of
ancient civilization started in the delta
of the Nile River and in the valleys of
the Tigris-Euphrates Rivers

18. The topography of the land likewise affects the
climatic condition of the place. The orientation and
height of the mountain system affects the distribution
of rainfall, local air currents, and temperature of the
region
The topography of the land is the most important
factor that limits its productivity
Landform is an important factor in human settlement
and development.
Slope, which is an element of landform, is a critical
factor. It is the angle of inclination of the land
measured from the horizon.

19. A geographic region is an area in which
there is some conspicuous unity in the
expression of the natural and cultural
setting.
. In the determination of the geographic
regions of the Philippines several factors
were considered such as landforms,
location, culture and the political
subdivisions of the country.

20. The Philippine Statistics present the
statistics and relevant information of
the regions of the country. The 18
regions of the Philippines are divided
according to major island groups,
landforms, and location of the
provinces.

22. Regional studies will provide the basis for regional
development which will in turn enhance national growth
and progress.
. This will provide opportunities for employment in the
countryside and may reduce the so-called “brain drain”
problem of the nation.
This will also minimize migration to the National Capital
Region which is already very thickly populated. Moreover,
consumer goods that will satisfy human needs may be
made available locally.
This will minimize the country’s imports and thus,
conserve our foreign exchange which can be utilized in the
importance of more vital needs for the nation.
