Here's why:
* "Terrarium" comes from the Latin word "terra", meaning "earth" or "ground". It refers to the enclosed space where plants are cultivated, resembling a miniature ecosystem.
* "Land" is a broader concept encompassing a wider area of ground, not necessarily focused on the earth itself.
While both terms relate to ground or earth, "terrarium" specifically denotes a controlled environment for plants, while "land" encompasses a broader geographic area.
