Step-by-step explanation:
The Western Front during World War I was located in France, Belgium, Great Britain, and Germany.
The Western Front was a key battleground in World War I, stretching from the English Channel to the Alps. It was characterized by the extensive use of trenches, where soldiers dug in to defend their positions.
France and Belgium were heavily impacted by the fighting on the western front, with major battles such as the Battle of the Marne and the Battle of Verdun taking place there. Great Britain also played a significant role, in providing troops and support to the Allied forces.
Germany, as one of the Central Powers, was on the opposing side of the western front. They initiated the war by invading Belgium and then advancing into France but were eventually halted by Allied forces.
