Question

in your textbook, read about pressure systems. complete the table by checking the correct column for each statement. 19. characterized by sinking air 20. characterized by rising air 21. air flows toward center 22. air flows away from center 23. air moves clockwise in the northern hemisphere 24. air moves counterclockwise in the northern hemisphere 25. associated with fair weather 26. associated with clouds and precipitation

Explanation:

• 19. Characterized by sinking air: High - pressure systems are associated with sinking air. As air sinks, it compresses and warms, which inhibits cloud formation.
• 20. Characterized by rising air: Low - pressure systems are characterized by rising air. Rising air cools, and as it cools, water vapor can condense to form clouds and potentially precipitation.
• 21. Air flows toward center: In a low - pressure system, air flows toward the center. This is because the pressure is lower at the center, creating a pressure gradient that draws air in.
• 22. Air flows away from center: In a high - pressure system, air flows away from the center. Since the pressure is higher at the center, the pressure gradient causes air to move outward.
• 23. Air moves clockwise in the northern hemisphere: In the northern hemisphere, high - pressure systems have air moving clockwise. This is due to the Coriolis effect, which deflects moving air to the right in the northern hemisphere.
• 24. Air moves counterclockwise in the northern hemisphere: In the northern hemisphere, low - pressure systems have air moving counterclockwise. Again, the Coriolis effect is at play, deflecting the inward - moving air (toward the low - pressure center) to the right, resulting in a counterclockwise circulation.
• 25. Associated with fair weather: High - pressure systems are typically associated with fair weather. As mentioned earlier, the sinking air in high - pressure systems inhibits cloud formation.
• 26. Associated with clouds and precipitation: Low - pressure systems are associated with clouds and precipitation. The rising air in low - pressure systems cools, allowing water vapor to condense and form clouds, and under the right conditions, precipitation can occur.
