Choosing the right word
  • 地ちJLPT N3approx.Common
    noun, noun (suffix)Ground, land, or soil in a general sense rather than dirt as a material. It is seldom the word you want on its own, serving mainly as an element inside larger words.
  • 土つちJLPT N3approx.Common
    nounSoil, dirt, or clay: the tangible material you dig, plant in, or get on your hands. This is the common word for actual soil, not for the planet or broad land.

  • アースCommon
    noun, suru verb, intransitive verb, transitive verbThe electrical sense only: the earth or ground of a circuit, and earthing or grounding. Use it for wiring and electrical safety; it has nothing to do with soil or the planet.

Use 土 for soil or dirt as material, 地球 for the planet, 大地 for the vast land underfoot, 「アース」 for electrical grounding, and 地 chiefly as an element in larger words for ground and land.
