What changed between WW1 and WW2

What changed between WW1 and WW2

WW1 and WW2 were constantly being fought over Land and rulership.
Even though many wars are the same there are many differences between
the two. During 1914 and 1945 these wars were continuously being fought.
And because of the impact of the first world war, many things have changed.

While WWI was fought in the trenches, by using machine guns and
poisonous gas to defeat the enemy. WW2 was much, much different. WW2
was fought using modern artillery and machines. They also used more
airplanes, ships, tanks, and submarines to attack the other side. In WW1
they used completely different weapons to defeat the enemy compared to
WW2. During WW2 they used a lot of machinery and air bombing. 

Unlike WW1, WW2 didn't use trenches and there was a lot more deaths
because of this. During WW2 lots more people died because of the lack of
shelter and protection. But in WW1 they had trenches to protect their
soldiers. Even though the soldiers during WW2 didn't have as good
protection as the soldiers who fought in WW1. They didn't have to deal
with all the nasty diseases like trench foot and deadly gases that entered the
trenches.

WW2 was fought because of the German leader Adolf Hitler, who was
trying to take over the world. Unlike WW2, WW1 was fought because of
the attempted assassination of Archduke Franz Ferdinand. The reasons for
these two wars being fought are completely different. The reason they are
so different is because of the causes. Because of this, they used different
methods. For example, WW1 used trenches to their advantage and used gas
to defeat the enemy. The reason for them using this is because of the cause.
It was more like a plan of revenge, rather than a war.

In conclusion, now you can see why WW1 and WW2 are very different.
The way they used weapons and the methods they used to protect
themselves are not the same. Some had to deal with illnesses. Others sadly
just died of injuries in war.
