Raul is on vacation at location X on the map below. His classmate, Cassy, is at location Y. Raul's location has a temperature of 14 C and a pressure of 1035 m.

Cassy takes pressure and temperature measurements at the same time as Raul, and she also adjusts her measurements to correct for her elevation above sea level. Which of the following tables could be her data?

•

The image was generated by the National Oceanic and Atmospheric Administration (NOAA) to monitor weather systems that could evolve into tropical cyclones. Satellite images and weather data have been entered into a computer model, which has identified three systems that might become tropical cyclones. Each system is associated with a different likelihood of turning into a tropical cyclone.

The figure suggests that there is _______ in the computer models used to make weather predictions.

• perfect accuracy

• some uncertainty

• zero accuracy

• no error

To prepare for the first day of school, Jeremy watches the weather forecast on television. The weather map he sees is shown. "H" indicates a high pressure system, "L" indicates a low pressure system, the blue line with triangular symbols indicates a cold front, and the red line with semicircular symbols indicates a warm front. A mixture of the two indicates a stationary front.

If Jeremy lives at point _______, he can expect mild weather conditions for his first day of school.

• W

• Z

• X

• Y

• warmer and more dense

• colder and less dense

• colder and more dense

• warmer and less dense
