5. This is the process, also known as spotting, by which winds and vertical convection columns carry hot wood embers and other burning materials through the air over roads, rivers, and other barriers.
8. Clouds form when water vapor in the air condenses around these small particles in the atmosphere.
10. In the United States, typically more than six times the number of wildfires are caused by _____________________.
11. Is a period of below-average precipitation in a given region, resulting in prolonged shortages in its water supply. In most parts of the world, this is a normal recurring feature of the climate.
12. The long-term variations in weather for a particular area.
15. The constant movement of water between the atmosphere and Earth’s surface is known as the _______________________.
16. This type of air mass will rise, and in doing so might produce enough energy for precipitation. For example, a warm air mass under a cooler one.
17. This wave of an earthquake has the highest velocity and is therefore the first wave to be recorded, which acts as a warning to those within the earthquakes danger zone.

2. These types of droughts affect crop production due to poorly planned agricultural endeavors.
3. This is created when friction between the updrafts and downdrafts within a cumulonimbus cloud separates electrons creating an electrical imbalance.
6. Violent downdrafts that are concentrated in a local area are called _________________.
7. An uncontrolled fire in an area of combustible vegetation that occurs in the countryside area (like a forest).
9. These waves are very destructive, and are made up Rayleigh or Love waves.
13. The short-term variations of the in the atmosphere.
14. This type of air mass will typically not rise, such as a cool air mass under a warmer one.
