In Minecraft, ores are valuable resources found underground that players can mine to gather materials. Each type of ore has unique properties and uses, such as crafting tools, weapons, and armor. Common ores include Coal, Iron, Gold, and Diamond, each requiring specific tools to mine effectively. Ores are typically found in specific layers of the game world, with some being more abundant than others. For example, Coal is often found near the surface, while Diamond is located deeper underground. Players can use these ores to enhance their gameplay experience and progress through the game.
