8th Grade Earth Science Exam Review Chap 16 Crossword
|
Down:
1) conditions are favorable for severe thunderstorms, tornadoes, floods, blizzards, and hurricanes3) Severe weather conditions already exist. Take immediate action.4) water falling from clouds5) Sinking motion in these kinds of air masses make it difficult for air to rise and for clouds to form. This usually means good weather.6) a measure of the amount of water vapor present in the air compared to the amount needed for saturation at a specific temperature7) a line that connects points of equal temperature.9) air containing moisture cooled the temperature at which the air is saturated and condensation forms.11) violent, whirling windstorm that crosses land in a narrow path and can result from wind shears inside a thunderhead12) Colder air advances toward warm air and wedges under warm air like a plow.
As warm air is lifted, it cools and water vapor condenses, forming clouds. When the temperature difference between the cold and warm air is large, thunderstorms and even tornadoes may form.13) Regions of rising air cause clouds to form when air is lifted and cools. This usually means cloudy weather.15) when water droplets form around dust particles and become heavy enough to fall out of the clouds. |
Across:
2) a large body of air that has properties similar to the part of Earth’s surface over which it develops8) when air hold all the water vapor it possibly can.10) the state of the atmosphere at a specific time and place, determined by factors including air pressure, wind, temperature, and amount of moisture in the air. It is the result of the sun’s heat and Earth’s air and water.14) a large, severe storm that
1. forms over tropical oceans,
2. has winds of at least 120 km/hr, and
3. loses power when it reaches land16) 1. rain
2. snow
3. sleet
4. hail17) the build-up of positive and negative electrical changes in clouds;
when current flows between regions of opposite electrical charges (positive and negative) clouds become oppositely charged18) a form where cold and warm air masses meet;
boundary between two air masses with different temperatures, density, or moisture; can be cold, warm, occluded, and stationary |
