Defintions
the study of atmosphere conditions and their effect on the weather
Meterology: It is based on what is happening in the atmosphere and how that influences our weather.
someone who studies weather and atmosphere conditions
Meterologist
Meterologists are always 100% accurate.
False
On what day did God create the firmament (atmosphere)?
a) day 2
b) day 5
A) Day 2
Air masses _____
a) can be both cold and hot
b) can only be cold
a) can be both cold and hot. When two different air masses (one cold and one hot) meet, it is a called a front.
the amount of water vapor in the air
Humidity
the area where two air masses meet
front-- usually it is said that a cold front (a large area of air with colder temp and less humidity) is meeting a warm front (a large area of air with warmer temp and more humidity)
Water covers 3/4 of the earth's surface. (meaning: if you divided the earth into four parts, three of them would be water and one of them would be land)
True
Job called air pressure _________.
a) strong wind
b) a hurricane
c) weight for the wind
C) Weight for the wind
Fresh water has
a) more salt in it than ocean water
b) less salt in it than ocean water
c) same amount of salt as ocean water
b) less salt in it than ocean water
any form of water that falls to the ground (water, snow, ice, etc.)
Percipitation
area where meterologists record their weather predictions for the next few days
weather map
Earth's air is made up of only oxygen gas.
False. Earth's air is made up of MANY different gases.
Some creation scientists believe that before their was rain on the earth, it was ____________.
a) dry and barren
b) covered by a water canopy
When you are hiking up a mountain, the air pressure will
a) decrease because the air is losing weight and becoming lighter
b) increase because the air is getting heavier and pushes down more
a) decrease because the air is losing weight and becoming lighter
This is why it gets harder to breathe the further up the mountain you go. It is becoming more spread out and therefore, harder to take in.
Huge bodies of air with about the same temperature and humidity
air masses -- they are large areas of air that have about the same temp and amount of water vapor (humidity)
a tool used to measure air pressure (or weight of the air)
barometer
Climate (or weather) can be affected by water and heat but NOT by air.
False. Our climate is affected by water, heat, and air.
When moist air rises and then cools, what happens?
a) water forms
b) clouds form
c) tornadoes form
d) strong winds
b) clouds form. This process is called condensation. The water vapor, which was heated, is now cooling, and the water droplets start to collect together forming a cloud. When the water droplets get too heavy for the cloud, it percipitates back to the ground below.
In our memory verse, Psalm 135:7, "He causes the vapors to ascend from the ends of the earth ...," the psalmist is mentioning which part of the water cycle?
a) evaporation
b) condensation
c) precipitation
d) run-off
a) e-vapor-ation
Something that determines the direction of the wind
(usually seen on top of barns in the shape of an animal with the four directions (N, E, W, S) on it)
Wind vane
a tool used to measure wind speed
anemometer-- Just think Anna's mom is measuring the wind speed
Frozen water is less dense than the same amount of liquid water. (Think: Does ice fall or float? Dense means it is heavier for its size.)
True. Frozen water (ICE) is less dense (is not heavier for its size) and that is why ice floats in a glass of water.
Remember: Normal liquids condense when they get colder (all their molecules get closer and move slower). HOWEVER, frozen water expands and breaks this rule.
Where do hurricanes form?
a) North Pole
b) over hot deserts
c) over cool lakes or oceans
d) over warm ocean waters
d) over warm ocean waters. Those heated waters start to evaporate and then cause more cool water to swoop in to replace the warm water that moved causing a spiraling of water-- a hurricane.
A tool used to measure wind speed is called a:
a) barometer
b) wind vane
c) anemometer
c) anemometer. Remember:Anna's mom is measuring the wind speed.
A wind vane shows the direction of the wind.
a barometer measures the air pressure. Remember: Barry's Mom measures the air pressure.
