8. Philippine Bodies of Water
• The north is bordered by the Babuyan
Channel.
• The west by the South China Sea
• The south by the Celebes Sea.
• The Philippines' eastern coast faces the
Pacific Ocean.

9. Philippine Bodies of Water
• Inland lakes and rivers exist within
the islands, formed through time by
different geologic activities.

10. What is a bay?
• a large body of water connected to
an ocean or sea formed by an inlet of
land due to the surrounding land
blocking some waves and often
reducing winds.

11. Example of a Bay in
the Philippines :
• Subic Bay is a bay forming part of
Luzon Sea on the west coast of the
island of Luzon in Zambales,
Philippines, about 100 kilometers
northwest of Manila Bay.

12. What is a river?
• A river is a natural watercourse usually
freshwater, flowing towards an ocean, a lake,
a sea, or another river.
• In few cases, a river simply flows into the
ground or dries up completely before reaching
another body of water.

13. Example of a River in the
Philippines :
• The Pasig River (called Ilog Pasig
in Filipino) - is a river in the
Philippines that connects
Laguna de Bay to Manila Bay.

14. Example of a River in the
Philippines :
• Pampanga River (formerly known as Rio Grande de
Pampanga) -is the second largest river in the island of
Luzon, next to Cagayan River and the third largest but
most important river in the Philippines. It is located in
the Central Luzon region and traverses the provinces of
Pampanga, Nueva Ecija, Bulacan, Tarlac and Quezon.

15. What is a waterfall?
• A waterfall is a place where water flows over a
vertical drop in the course of a stream or river.
• Waterfalls also occur where meltwater drops
over the edge of a tabular iceberg or ice shelf.

16. Example of a Waterfall
in the Philippines :
Maria Cristina Falls is a waterfall that can
be found in Iligan City. Sometimes called
the "twin falls" as the flow is separated by
a rock at the brink of the waterfall.

17. What is a sea?
• A sea is a large body of saline water that may
be connected with an ocean or may be a large
saline lake that lacks a natural outlet.

18. Example of a Sea in the
Philippines :
Camotes Sea - is a small sea within the Philippine
archipelago, between the Eastern Visayas and the
Central Visayas. It is bordered by the islands of
Leyte to the north and east, Bohol to the south,
and Cebu to the west.

19. What is a hot spring?
• A hot spring is a spring that is
produced by the emergence of
geothermally heated groundwater
from the Earth's crust.

20. Example of a Hot Spring
in the Philippines :
The Tangub Hot Spring can be found in Camiguin.
It is in the sea at normal water level. At low tide,
the warm water comes out between the rocks.

21. What is a gulf?
• A gulf is a body of water that is
connected to a sea or ocean. There will
be land partially surrounding the
water, but it is larger than a bay. A gulf
is often a long or large landlocked part
of the sea that opens at a strait.

22. Example of a Gulf in the
Philippines :
Davao Gulf is a gulf found in Mindanao in the
Philippines. It has an area of 308,000 hectares.
Davao Gulf cuts into the island of Mindanao from
Philippine Sea. It is surrounded by all four
provinces in the Davao Region.

23. What is a strait?
• A strait is a narrow, typically
navigable waterway that connects
two larger, navigable bodies of
water.

24. Example of a Strait in the
Philippines :
• San Juanico Strait is a narrow strait
in the Philippines. It separates the
islands of Samar and Leyte.

25. What is a stream?
• A stream is a body of water with a
current, confined within a bed and
stream banks.
• A stream is a body of running water
moving to a lower level in a channel
on land.

26. Example of a Stream in
the Philippines :
• Tandawan Stream is a
stream in Davao, Philippines.

27. What is a lake?
• A body of relatively still water of
considerable size, localized in a basin,
that is surrounded by land apart
from a river, stream, or other form of
moving water that serves to feed or
drain the lake.

28. Example of a Lake in the
Philippines :
• Laguna de Bay - is the largest lake in the
Philippines located east of Metro Manila
between the provinces of Laguna to the south
and Rizal to the north.

29. TAAL LAKE

30. TAAL LAKE
Taal Lake is found in the
province of Batangas, on the
island of Luzon in the
Philippines.

31. TAAL LAKE
• Taal Lake was once just an arm of
Balayan Bay.
• However, after a series of major
eruptions in the 18th century, Taal
Lake's sole connection to the sea
narrowed down into its sole draining
river, the Pansipit River.

32. TAAL LAKE
• Several centuries of precipitation
have diluted the lake's once saline
waters into freshwater.
• Because the lake was until
recently connected to the sea, it is
home to many endemic species
that have evolved and adapted to
the desalination of the lake's
waters.

33. Examples of species in
Taal Lake :
• Harengula Tawilis
a freshwater sardine found exclusively in the
Philippines. It is unique in that it is the only
member of the family Clupeidae that is
known to exist entirely in freshwater.

34. Examples of species in
Taal Lake :
• Mullets or Mugilidae
are distinguished by the presence
of two separate dorsal fins, small
triangular mouths, and the
absence of a lateral line organ.

35. TAAL LAKE
• Taal Lake’s soil is Fine Sandy Loam.

36. TAAL LAKE
• It is the deepest lake in the Philippines
(172 m) and the third largest in area
(234.2 km2).
• It is a caldera lake, having been formed
partly by the collapse of a large
volcanic crater and partly by
subsidence.

wonderful day!
