Across
- 2. Forms at the surface of Earth when a warm, moist air mass overtakes a cool, dense, and dryer air mass.
- 3. An air mass with greater atmospheric pressure than the surrounding air masses, air moves away from the high pressure, traveling in a clockwise direction.
- 6. An air mass with less atmospheric pressure than the surrounding air masses, air moves toward the low pressure, traveling in a counterclockwise direction.
- 9. Atmospheric air pressure is the force exerted on Earth's surface by the weight of the air above the surface
- 10. The day-to-day state of the atmosphere.
- 11. Forms at the surface of Earth when a cold, dry air mass overtakes a warmer, humid air mass.
Down
- 1. An instrument that measures the amount of atmospheric pressure.
- 4. Global air circulation patterns within the atmosphere held to Earth by gravity and warmed as heat radiates from Earth; influenced by convection of warm less dense air (rises and spreads out) and cold dense air (sinks).
- 5. An air mass is a body of air extending over a large area (1000 miles or more) that develops and retains specific characteristics of pressure, temperature, and humidity.
- 7. A weather map or chart shows the weather conditions at a specific point in time over a specific region.
- 8. Specialist who studies the science of Earths atmosphere and the causes of weather conditions.
