Final answer:
The Second World War differed from the First World War in terms of aerial bombing, scale, and technological advancements.
Step-by-step explanation:
Three fundamental ways in which the Second World War differed from the First World War:
- The Second World War involved the aerial bombing of important cities, resulting in large numbers of civilian casualties. This was a new element of warfare that was not present in the First World War.
- The Second World War had a much larger scale and involved a greater number of nations. The armed forces of the warring nations numbered about 30 million, and the total number of individuals killed, military and civilian, was likely between 35 and 40 million.
- The Second World War saw the introduction of new military technologies, such as increased air bombardment and projectile weapons like rockets. These technological advancements made the war even deadlier and more destructive than the First World War.
