Notes
GENERAL INFO
Terre is a feminine noun meaning "earth" (the planet), "land," or "soil."
USAGE
It's used for the planet ("La Terre tourne"), ground/soil ("cultiver la terre"), or a specific piece of land ("ses terres agricoles"). You can also say "par terre" (on the ground).
TRAPS
Distinguish between "La Terre" (the planet, capitalized) and "une terre" (soil/land). Do not confuse it with "monde" (world/people), which has a broader meaning than just the physical ground.
