SCI10-Q1-LESSON3 MOUNTAIN BELTS IN PHILIPPINES Mountains are usually formed by different geological processes like the movement of tectonic plates. These landforms are present all over the Philippine archipelago. Groups of these mountain ranges that are similar in form, structure, and alignment are referred to as mountain belts. Mountain Ranges in the Philippines The most prominent range in the country is the Central Cordillera, the central mountain chain of Luzon which cuts across the north to the Luzon Strait from the northern boundary of the central plain. The Central The Sierra Madre Mountain Range is the longest Cordillera is an orogen. An orogen is a belt of Earth’s crust mountain range in the country.

The Zambales Mountains lie on the western island of Luzon. It is an ophiolite, an abducted slice of oceanic crust emplaced during subduction. It separates Luzon’s central plain from the South China Sea. It extends from western Pangasinan province, the whole length of Zambales, to the tip of the Bataan Peninsula in the south. Its most noticeable feature is the Cabusilan Mountain Range comprising Mt. Pinatubo, Mount Negron, and Mount Cuadrado.
