Across
- 1. the boundary between two air masses that have different temperatures and densities. There are four types of fronts: cold front, warm front, stationary front, and occluded front.
- 3. front: a weather front where a cooler air mass replaces a warmer air mass. Cold fronts often bring rain and thunderstorms
- 7. zone: the climate zone near the equator, where average temperatures are warm.
- 11. A person who studies weather and its patterns.
- 14. Zone: are areas with distinct climates, which occur in an east-west direction around the Earth, and can be classified using different climatic parameters.
- 16. the sound caused by the rapid expansion of air during a lightning strike.
- 19. an electrical discharge between positively and negatively charged surfaces, either between clouds or between a cloud and the ground.
Down
- 2. zones: the climate zones between the polar zones and the tropical zone. Average temperatures in temperate zones have a wide range, and are warmer near the tropical zone and cooler near the polar zones.
- 4. the distance north or south of the equator.
- 5. front: a weather front where a warm front is between two cold fronts. Occluded fronts may bring continuous rain or snow.
- 6. Disaster: a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.
- 8. zones: the climate zones near the north and south poles, where average temperatures are very cold.
- 9. front: a weather front where a warm air mass is replacing a cold air mass. The less dense warm air mass moves over the denser, cold air. Warm fronts often bring light rain followed by clear, warmer weather.
- 10. the pattern of weather over a long period of time (like 30 years)
- 12. the current conditions of the atmosphere at a particular place and time.
- 13. movement of air caused by differences in air pressure.
- 15. any moisture that falls to Earth (rain, snow, hail, sleet, or mist)
- 17. a collection of tiny water droplets or ice crystals suspended in the air.
- 18. front: a weather front where a cold air mass and a warm air mass move toward each other. Stationary fronts often bring extended periods of rain.
