Erdoberfläche vs Boden
floor / ground
'der Boden' and 'die Erdoberfläche' can both refer to a surface that belongs to the earth. But 'Boden' is much more everyday and is thought of on a smaller scale: you stand on the 'Boden', wipe the 'Boden', or plant something in the 'Boden'. 'Erdoberfläche' means the outer surface of the entire planet, including land and bodies of water. The word fits more in geography, natural science, or large-scale contexts. They can be confused because both describe something beneath or around us. In everyday life, people usually say 'Boden'; for global or scientific topics, 'Erdoberfläche' is more common.
Erdoberfläche

Boden
