The data that best supports the scientist’s decision to issue the drought warning is:

Reservoirs and lake levels continue to drop significantly.

This data directly indicates a lack of water availability, which is a key factor in determining drought conditions.

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.

The response that best explains how a controlled burn limits the spread of wildfires is:

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

This strategy reduces the amount of available fuel for a wildfire, thereby helping to prevent its spread.
