Answer:
Most major rivers in Southeast Asia seem to flow in the same direction. By studying the physical geography of this region, we can tell that these rivers flow from north to south because the major mountain ranges run from north to south. The rivers formed naturally between them in valleys.
They are close to the equator, another reason is because of the tropical maritime location, temperature changes throughout the region are generally small.
Volcanoes can form underwater thats how Hawaii was made
