Surface fires burn along the soil surface, consuming fuels that lie on or very near the ground—such as grasses, leaves, and low shrubs. This makes them the right description for a fire that stays on the surface and uses those ground-level fuels. It’s different from a ground fire, which burns organic matter beneath the surface, like duff or peat, and from a crown fire, which spreads through the tree canopy. A line fire isn’t describing the fuel layer—it's a term often used for spreading along a prepared line to stop or guide a fire, not for a ground-cover burn.
