A Weather Forecasting System Review
Circle your answer as you go. Mark it right or wrong as you go.

2. 1.Earth’s weather occurs almost completely within what atmosphere layer?

This is where we live

4. 2.What is the boundary between two unlike masses of air?
A) station model
B) knot
C) front
D) prevailing wind

5. C) front
This is the boundary where air masses of different temperatures and humidities collide.
There are 4 types

6. 3.Examples of precipitation are
A) snow, fog, dust
B) clouds, rain, sun
C) tornadoes, hurricanes, blizzards
D) rain, sleet, hail

7. D) rain, sleet, hail
After water vapor condenses in a cloud it can fall in different forms depending on the temperature.

8. 4. On a weather map, a line with a row of triangles on one side shows the location of a ___________?
A) a cold front
B) a mountain range
C) lightning strikes
D) fog

9. A) A cold front
This is when a cold air mass moves in and overtakes a warm air mass.
It brings cold temperatures, clouds, and rain immediately.

10. 5. Weather stations collect data about all the following EXCEPT _________.
A) temperature and humidity
B) thermometers and barometers
C) cloudiness and precipitation
D) air pressure and wind

11. B) Thermometers and barometers
These are TOOLS used to measure data

12. 6. A front moving toward an area usually means _______
A) the greenhouse effect
B) changing weather
C) no change in weather
D) a tornado forming

13. B) Changing weather
When a weather front moves in it usually means weather will change because it is a different temperature of air mass.

14. 7. What does climate mean? A) daily weather B) high temperature
C) average weather over a long period of time.
D) cold front

15. C) Average weather of a long period of time
Weather is just the current daily weather while climate is an average over a long period of time.

16. 8. High, thin, wispy clouds that are made of ice crystals are_______.
A) cirrus
B) cumulus
C) stratus
D) nimbus

17. A) cirrus Cirrus clouds are the highest in the sky.
They have a feather or hair like appearance.
It’s a fair weather cloud.

18. 9. What would measure wind speed accurately?
A) a Celsius thermometer
B) a hygrometer
C) the beaufort scale
D) an anemometer

19. D) An anemometer
A Beaufort scale is only an observation to rate wind speed. An anemometer is a tool used to accurately detect the speed of wind.

20. 10. In sunny, dry weather, the air pressure is ______ and the relative humidity is ________.
A) low, high
B) high, low
C) high, high
D) low, low

21. B) high, low
Warm weather comes after a high pressure mass has moved in. Dry weather has low humidity.

22. 11. Two factors can cause clouds to form when water vapor cools
11. Two factors can cause clouds to form when water vapor cools. They are _______________.
A) humidity and high pressure
B) precipitation and convection
C) condensation and dust particles
D) evaporation and low pressure

23. C) Condensation and dust particles
The water vapor needs something to condense on like dust particles.
Think of the experiment “Make a Cloud” and how we used smoke for particles for the water vapor to condense on.

24. 12. The scientific study of weather and the atmosphere is called ____________________
A) Biology
B) Meteorology
C) Astrology
D) Climatology

25. Meteorology

26. 13. Puffy, cotton-like clouds are _________________.
A) Cumulus
B) Nimbus
C) Stratus
D) Cirrus

27. A) Cumulus Cumulus clouds are known as the fair weather clouds.
They often are puffy on the top and flat on the bottom.

28. 14. A line on a weather map connecting points with equal air pressure is a/an _____________.
A) Isotherm
B) weather front
C) Isobar
D) Spilled Milk

29. C) Isobar

30. 15. This instrument measure air pressure.
A) barometer
B) thermometer
C) anemometer
D) Steven’s Screen

31. A) barometer
A barometer measure air pressure in psi (pounds per square inch) and millibars.
If the barometric pressure falls, you can usually expect stormy weather,
If the barometric pressure goes up, you can expect warm dry weather.

32. 16. A prediction on weather conditions for a particular area and time period is ______________________.
A) a hypothesis
B) a psychic reading
C) a guess
D) a forecast

33. D) Forecast

34. 17. When a meteorologist collects data from high up in the atmosphere , it probably came from _______________.
A) a satellite dish
B) a weather balloon
C) An almanac
D) a surface map

35. B) Weather balloon

36. 18. Why does air get colder as you go up in elevation?
A) The sun heats the surface of the earth so as you get further from the surface it gets colder.
B) The air actually gets warmer because warm air rises.
C) The air temperature is the same near sea level as it is at higher elevations.

37. A) The sun heats the earth’s surface.
The sun does not heat air molecules; it heats the surface (solid) of earth (at sea level)
So the further you get from the surface of the earth the colder it gets.

38. 19. A condition of weather that we measure is _______________.
A) temperature
B) air pressure
C) wind speed
D) All the above

39. D) All the above
There are 5 conditions that are measured: temperature, air pressure, wind, humidity, and precipitation.

40. 20. Hurricanes and Tornadoes have centers with very low _____________.
A) temperatures
B) humidity
C) clouds
D) air pressure

41. D) Air pressure
The center of the hurricane or tornado is called the “eye of the storm”.
It is very calm.
