What is Precipitation?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth
What is Humidity
The amount of moisture in the air at a given temperature
What is this and what does it measure?
Wind Vane: direction of wind
Why do farmers need to know the weather?
Prepare for bad weather conditions (hail storms, tornados, etc)
Tornados occur over the water
False: Hurricanes
warm water evaporates, rises with warm air, hits cold air at high elevations and condenses into clouds.As water vapour rises/falls/condenses, it swirls into a GIANT storm
Name 4 elements of weather?
Wind, sunlight, cloud cover, temperature, atmospheric pressure, humidity, precipitation
How does altitude effect temperature?
It gets colder the higher you are in altitude.
What is this and what does it measure?
thermometer: air temperature
A bear hibernating (sleeping over the winter) signals a change in what?
(weather, seasons, temperature, its cave)
Season
Earthquakes are a weather event
False: earthquakes are caused by the earth's tectonic plates shifting
Climate/Weather happens over a short period of time.
Weather
Name 3 global climate zones. There are 5.
Tropical, dry, temperate, continental, polar
What is this and what does it do?
Anemometer: measures wind speed
Bees returning to the hive signals a change in?
(weather, climate, seasons, honey)
Weather. Bees return when they sense the weather will change. (eg. storm)
Blizzards are caused by cold air, low pressure systems, mountains or another obstacle to help produce winds.
True
What causes wind?
Shifting air pressure: high to low pressure
What climate zone does Calgary reside in?
Continental
What is the device called that measures moisture in the air?
Hygrometer
What is conservation agriculture?
When farmers use methods to protect soil, and improve crop/plant production.
This includes: crop rotation, soil protection, reducing soil disturbance
Fog is caused by hot sun.
False: fog is caused when water droplets condense in the air that stay suspended from cold air.
Explain the main difference between weather and climate
What climate zone am I?
Low humidity, few plants and animals,
Low rainfall, varying temperature
Dry Climate: dessert
What is the device that measures air pressure called?
Barometer
Describe how a type of weather could be good or bad for farmers? (e.g. rain)
Enough rain helps plants grow. Too much, drowns plants/crops.
Thunderstorms form when cold, dry air rises into warm air. The cold air becomes warmer and forms small water droplets. The warm air drops, warms, and rises again. This rising and falling air creates a thunderstorm.
False:
Thunderstorms form when warm, moist air rises into cold air. The warm air becomes cooler and forms small water droplets. The cooled air drops, warms, and rises again. This rising and falling air creates a thunderstorm.
