The National Park Service sometimes creates controlled burns to mitigate wildfires. How does a controlled burn limit the spread of wildfires?
1.) A controlled burn helps to remove plants and vegetation around buildings so a wildfire won’t destroy them.
2.) A controlled burn temporarily shuts down parks so people won’t start campfires.
3.) A controlled burn is used to make a path that helps a spreading wildfire arrive at a source of water.
4.) A controlled burn removes dead vegetation that might otherwise help a wildfire start and spread.
