Final answer:
The Easter Front was characterized by highly mobile warfare and large-scale movements, while the Western Front was defined by the static nature of trench warfare.
Step-by-step explanation:
The Easter Front and the Western Front were two major fronts during World War I. The Easter Front refers to the conflict between the Russian, German, and Austrian armies in Eastern Europe, while the Western Front refers to the conflict between the German, French, and British armies in Western Europe.
On the Easter Front, the armies were highly mobile and engaged in large-scale movements and outflanking maneuvers. The Russians initially had success against the Austrians, but were ultimately defeated by the Germans due to their superior maneuverability and lack of support. On the Western Front, trench warfare was the dominant form of combat, with both sides digging in and engaging in unsuccessful attempts to break through the enemy's trench lines. The Western Front became a stalemate that lasted for four years.
