The kanji and the word are exactly the same. That means they share meanings as well.

地 is often used in formal contexts or literature to refer to the Earth's surface, the ground, or land in a more abstract or overarching sense. To say "earth" or "ground" casually, use 地面. For "land," it's 土地.

Although this is a single kanji all alone, it uses the on'yomi reading. This is the reading you learned with the kanji, you lucky duck.
