Geologically speaking, the Philippine archipelago was formed by volcanic eruptions from under the sea and the buckling of the earth’s crust when two tectonic plates collided about 65 million years ago.
How did the Philippine archipelago was formed?
The Philippines did not break out from Pangaea. Rather, the Philippine islands were formed by volcanic eruptions that occurred under the Pacific Ocean over millions of years. … Over millions of years and many eruptions, this hardened magma eventually formed the land of the Philippine islands.
