Lesson 3 - Physical Features, Geological-Geographical Foundation And Peopling Of The Philippines Flashcards
What are the three (3) identified hypothesis about the geological and geographical foundation of the Philippines
- Part of the Pacific Lost Continent
- Volcanic Origin
- Land Bridges
Believed that the Philippines was a remnant of a vast continent in the Pacific that had sunk during pre-historic times
Part of Pacific Lost Continent
What was the lost pacific continent called?
“Lemuria” or “Mu”
What were the other remnants of the lost pacific continent other than the Philippines?
- Borneo
- Celebes
- Java
- Sumatra
- other islands of the Pacific
The Philippines was born due to the eruptions of sea volcanoes in remote epochs.
Volcanic Origin
Who proposed the volcanic origin hypothesis?
Dr. Bailey Willis, geological engineer
Resulted in the formation of islands in the Philippines
Spewed magma piled up and cooled down
Why do other believe the volcanic origin hypothesis?
Because of the presence of several active volcanoes
The Philippines is within what is called the __ __
Seismic belt (Pacific Ring of Fire)
Theory suggests that the Philippines was once part of a landmass bridging
Land Bridges
What were the countries that was once part of a landmass bridging?
- China
- Asian Mainland
- Borneo
- Indonesia
- New Guinea
- Australia
When did the world’s ice sheet melt?
During the post-glacial age about 250,000 years ago
The two (2) extensions of continents, otherwise known as continental shelves, exposed during glacial periods
- Sunda Shelf
- Sahul Shelf
Extension of the coastal shelf of Southeast Asia
Sunda Shelf
What were included in the Sunda Shelf?
- Malay Peninsula
- Sumatra
- Java
- Borneo to Palawan
From Borneo, the Philippine was linked through a narrow projection of island now occupied by __, __, and __.
Balabac, Palawan, and Calamianes
An extension of the coastal self of Australia
Sahul Shelf
What were included in Sahul Shelf?
- New Guinea
- Aru Islands of Indonesia
What are the following plausible reasons supplying the Land Bridges theory?
- The similarity of fauna and flora in Asia and the Philippines.
- The similarity of rock structure.
- Existence of the shallow China Sea between the Asia Mainland and the Philippines.
- The presence of a foredeep at the eastern margin of the Philippines indicating the archipelago was once the edge of the Asia continental Platform.
