Several parts combine into one character.

Phonetic-semantic compound: 土 (earth, the previously discussed altar/soil character) + 也 (a phonetic component). Where 土 means physical dirt and 大地 means abstract earth-as-place, 地 alone covers the location/ground/region sense — a more abstract sibling of 土. Identical across 繁體 / 新字体 / 简体.

Mandarin has TWO crucial readings for 地: — dì (4th tone): ground / earth / region / place. 地球 (dìqiú, Earth — the planet), 地图 (dìtú, map), 地方 (dìfang, place — neutral final tone, very high frequency), 地铁 (dìtiě, subway — "earth iron"), 地址 (dìzhǐ, address), 土地 (tǔdì, land). — de (neutral tone): a grammatical particle that turns adjectives into adverbs. 慢慢地走 (mànmàn de zǒu, "walk slowly"), 高兴地说 (gāoxìng de shuō, "happily said"). This pattern — adjective + 地 + verb — is one of the foundational Mandarin grammar structures. Learners must distinguish dì (the noun) from de (the particle); the same character does double duty.

Japanese: TWO on-readings. チ (chi) is dominant — 地球 (chikyū, Earth/planet), 地理 (chiri, geography), 地方 (chihō, region), 地下 (chika, underground). ジ (ji) appears in 地面 (jimen, ground / surface), 地震 (jishin, earthquake — every Japanese resident's essential vocabulary), 地味 (jimi, plain / understated — culturally important Japanese aesthetic adjective). Kun-readings are essentially absent — 地 is exclusively on-reading in Japanese practice.

The Japanese cultural keyword 地震 (jishin, earthquake) — given Japan's position on the Pacific Ring of Fire — is among the first essential vocabulary for visitors. Every Japanese building displays 地震対策 (earthquake preparedness) signs.

Memory aid: earth-soil (土) + phonetic — the abstract "ground" beneath everything.
