Science Weather

The data table below shows apparent air temperature in degrees Fahrenheit (°F). Apparent air temperature is how hot the air feels at different air temperatures and different relative humidity.

If the air temperature is 90°F and the relative humidity is 70%, the apparent air temperature is

• 20°F

• 106°F

• 71°F

• 113°F

The photograph shows a satellite image of a

hurricane. A satellite image of a hurricane helps weather forecasters to

• warn residents of hazardous weather conditions

• explain the effects of global warming on the

  ocean currents

• predict the times of high tide and low tide

• predict the total number of storms to occur in

  one year

Base your answer on the weather map and on your knowledge of science. The center of a storm system (Low) over part of the United States and the frontal boundaries associated with this system are shown. Point A represents a location on the map.

Precipitation is most likely occurring at A because it is located

• on a cold ocean surface

• near the cold front

• on a warm land surface

• near the warm front
