True/False
___11. The unit that is commonly used to express atmospheric pressure on a weather map is the millibar.
___12. Lines on a weather map that connect places of equal air pressure are called isotherm.
___13. The Coriolis effect deflects winds to the right of their path of motion in the Southern Hemisphere.
___14. Cyclones are low pressure centers, and anticyclones are high pressure centers.
___15. In the midlatitudes, between 30 and 60 degrees latitude, the general west to east flow of air is interrupted by the migration of cyclones and anticyclones.
___16. Standard sea-level pressure is 1013.2 millibars, which equals 29.92 inches of mercury.
___17. With increasing altitude, air pressure increases rapidly at first, then much more slowly.
___18. Winds blow from areas of higher pressure toward areas of lower pressure.
___19. Cloudy conditions and precipitation are often associated with the passage of a low-pressure center.
___20. Warm, dry winds called Chinooks are common on the eastern slopes of the Rocky Mountains.
