the amount of water vapor in the air
the speed of wind caused by the air

Humidity measures the amount of water vapor in the air.

Answer 2

What technique had been used by Native Americans for thousands of years and is now used today by agencies such as the U.S. Forest Service to prevent the spread of wildfires?
Thinning
Global Positioning Satellite (GPS)
Controlled burns
Use fire-resistant outdoor furniture

Answer 3

The technique that had been used by Native Americans for thousands of years and is now used today by agencies such as the U.S. Forest Service to prevent the spread of wildfires is controlled burns.

Answer 4

How does Global Positioning Satellite (GPS) help to make the effects of wildfires less severe?
GPS lowers air temperature and winds during times of high risk for wildfire.
GPS is the emergency notification system that alerts communities when it is safe to re-enter their homes after the threat of a wildfire. GPS identifies the borders of the wildfire and use data to predict where the fire will spread.
GPS is the material that homes and other items are constructed from that make them fire-resistant.

Answer 5

Global Positioning Satellite (GPS) helps to make the effects of wildfires less severe by identifying the borders of the wildfire and using data to predict where the fire will spread.
