Weather and Atmosphere Weather Instruments Clouds and Precipitation Air Masses and Fronts Extreme Weather rd Quarter- 6 th Grade Science Jeopardy- Test #2

10 points Question: Identify the four characteristics of the weather. Answer: Temperature, pressure, moisture, and wind

20 points Question: When air moves from areas of high pressure to areas of low pressure, what is this called? Answer: Wind

30 points Question: The state of the atmosphere at any specific time is known as… Answer: Nitrogen = 78% Oxygen = 21%

40 points Question: Explain how the temperature of air is affected by your position on Earth. Answer: If you are closer to the north and south pole, it is cold. If you are closer to the equator, it is warmer.

50 points Question: What causes the differences in temperature on the Earth, which ultimately also creates the wind? Answer: The uneven heating of Earth by the sun.

10 points Question: What are the two most common units used to measure the temperature of the atmosphere? Answer: Fahrenheit, Celsius

20 points Question: What does a rain gauge measure? Answer: The amount of liquid precipitation during a rain storm.

30 points Question: What does a sling psychrometer measure and anemometer measure? Answer: Sling Psychrometer = Relative Humidity Anemometer = Wind Speed

40 points Question: How is a hygrometer different than a slign psychrometer? Answer: A sling psychrometer measure the humidity in the air relative to the temperature, while a hygrometer measures the absolute moisture.

50 points Question: Identify the weather instrument and the units we learned about for those weather instruments. Answer: mm/hr, millibars, fahrenheit, and knots

10 points Question: What does the word ‘cumulus’ describe about a cloud? Answer: Shape

20 points Question: Identify the three types of cloud shapes. Answer: cumulus, stratus, and cirrus

30 points Question: What characteristic of the atmosphere controls what type of precipitation falls? Answer: Air temperature

40 points Question: How does the amount of time precipitation lasts for in a cold front compare to that of a warm front? Answer: Precipitation lasts for a short time in a cold front, and a long time in a warm front.

50 points Question: Why does it rain? Answer: When warm, moistj air rises over cool air, water vapor will undergo condensation. As condensation continues, the water droplets inside of the cloud grow too large and fall.

10 points Question: What are the two properties of air masses? Answer: moisture and temperature

20 points Question: What words are used to describe the amount of moisture and temperature in an air mass? Answer: Continental/Maritime, and Tropical/Polar

30 points Question: What type of front results when two air masses slide past each other? Answer: Stationary Front

40 points Question: Describe where each of the air masses originates form, and what type of front might be associated with each: continental polar, martime tropical. Answer: Continental Polar: over land at high latitude, and a cold front Maritime Tropical: over the ocean at lower latitude, and a warm front

50 points Question: In at least four unique ways, how do cold front differ from warm fronts? Answer: Temperature, precipitation, storms produced, duration of precipitation, shape of front

10 points Question: What is two (2) ways hurricanes different than tornadoes? Answer: In size, shape, wind speed, area of formation

20 points Question: How many categories can hurricanes be divided into? Answer: Five (5)

30 points Question: As a cold air mass moves into an area during a hot summe day, what happens to the warm air as thunderstorms are created? Answer: The warm air rises and condenses to form thunderstorm clouds

40 points Question: Identify at least four (4) of the five (5) severe weather hazards as stated by the National Weather Service? Answer: Hail, straight-line wind, lightning, floods, and tornadoes

50 points Question: Explain in detail the process by which hail forms in a thunderstorm. Answer: Rain gets sucked into an updraft in a powerful thunderstorm, and as it rises higher in the atmosphere, it cools down and freezes. The frozen rain moves around in the cloud over and over again, and layers form around it. When it gets too heavy foor the updrafts to hold it, it falls to the ground as a layered ice ball.
