Minecraft wiki entry for Survival, associated text: In Survival mode, the player is able to receive damage from the environment (fall damage, suffocation, lava, and freezing) and from hostile mobs (unless playing on Peaceful, where hostile mobs are disabled). A player who receives enough damage dies and returns to the world spawn, or to a previously slept-in bed, or in the Nether to a respawn anchor if the player set one.
