Question

the national park service sometimes creates controlled burns to mitigate wildfires. how does a controlled burn limit the spread of wildfires? (1 point)

a controlled burn removes dead vegetation that might otherwise help a wildfire start and spread.

a controlled burn is used to make a path that helps a spreading wildfire arrive at a source of water.

a controlled burn helps to remove plants and vegetation around buildings so a wildfire wont destroy them.

a controlled burn temporarily shuts down parks so people wont start campfires.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Controlled burns remove dead vegetation (fuel) that wildfires need to spread, which is a key way to limit wildfire spread.
• Option 2: Controlled burns don't guide wildfires to water; their purpose is to reduce fuel, not direct fire.
• Option 3: Controlled burns for building protection are not the primary way they limit wildfire spread (they target broader fuel reduction, not just around buildings).
• Option 4: Controlled burns don't shut down parks to prevent campfires; they manage fuel for wildfire mitigation.

Answer:

A. A controlled burn removes dead vegetation that might otherwise help a wildfire start and spread.
