science and technology played a major role in developing new weapons
because weaponised machinery had not been used on such a large scale before as it had been in ww1?
WW I was bigger than previous wars, because all the powerful nations of the world were involved on one side or the other, in two vast, opposed alliances (the Triple Entente vs. the Central Powers). No previous war had involved the whole world.
I Believe that we had world wars because the countries didn't agree on something or just that some maniac like Hitler in WW2 want to start a fight because they lost a previous war and they had to clean up the mess that was left.
These wars are known as World Wars because many countries of the world fought in the war
Because everyone had to make major changes to adjust to all the technological advances during the war
that theres different contrys in each war
Some wars were called World Wars because they were fought with a variety of countries all around the world in different places. An example would be World War 1.
Because it was involved of the whole world at war, America, Europe, Asia, Oceanic and Africa had effects from the wars
no
Too many to count.
the 2 wars (world war1 and world war2 are related because there was a lot of dist ruction and many people died
The French 75, the machine gun and the aircraft.
