Answer:
For starters, the terrain, the people, the weapons.
Explanation:
North Africa was rocky and mountainous in some places, and more easily acessed in other places. It is a desert region, and arid year round. The islands on which the war in the pacific was held were mountainous in some areas, and comprised mostly of jungle and wetlands.
While the war in North Africa was fought by the Nazis, Arab sympathizers of the Nazis, the British and their various allies, and the American troops, the war in the Pacific was fought by the Imperial Japanese, the British navy and marines, and the American navy and marines.
The war in North Africa was fought heavily with tanks, but the Pacific was too inaccessible to the allies for them to be practical. In their stead were amphibious vehicles like those that are used today by the modern Marine Corps, and flame throwers were used to a great extent to flush the Japanese out of their fortifications, usually caves and systems of tunnels.
