Water Cycle
What is precipitation?
When rain, sleet, or snow falls from a cloud
What is an air parcel?
A unit of air that moves together
What is air pressure?
the force of air molecules above/around something
What is weather?
atmosphere conditions over a short period of time
What is Mr. Lui's favorite sport?
soccer
What is evaporation? Explain using energy
The process of liquid (water) gaining energy and becoming a gas (water vapor).
Does the energy in an air parcel increase or decrease as it rises in the troposphere? (one word response)
decrease
Air moves from areas of ______ pressure to areas of ______ pressure
high, low
What is climate?
weather over a long period of time
9
What is condensation? Explain using energy
The process of a gas (water vapor) losing energy and becoming a liquid (water).
Does condensation increase or decrease as the difference between air parcel temp and surrounding air temp increases? (one word response)
increases
If it is HIGH pressure in San Francisco and LOW pressure in Dublin, what direction is the wind moving? (Hint: From Dublin to SF, you need to drive west).
East
the layer of the atmosphere closest to Earth’s surface
What college did Mr. Lui go to?
UC Irvine
As an air parcel rises HIGHER in the troposphere, ______ _______ to the surrounding air and the temperature of the air parcel ___________.
loses/transfers energy, decreases.
Why would warmer air parcels lead to more precipitation? Explain using energy, condensation, rise
Warmer air parcels means more energy in the air parcel and it would rise higher, lose more energy, have more condensation/precipitation.
Weather pattern A: pressure at parcel = pressure around parcel
Weather pattern B: pressure at parcel < pressure around parcel
Which weather pattern (A or B)would lead to more rainfall? (one letter response)
B
warmest, coldest
How many brothers does Mr. Lui have?
2 brothers
List 3 ways precipitation could be increased.
Increase surface water
Increase sunlight to surface
Increase water vapor in air parcel
Decrease surrounding air temp
Increase air parcel temp
Decrease pressure at the parcel
Increase pressure around the parcel
What settings would lead to the air parcel that rains the most? Use the abbreviated terms when answering (S, SW, PaP, ParP)
Sunlight (S): 1-5
Surface Water (SW): 1-5
Pressure at Parcel (PaP): 1-3
Pressure around Parcel (ParP): 1-3
S: 5
SW: 5
PaP: 1
ParP: 3
Why is there usually a greater chance of rain at "low pressure systems?" Explain using energy transfer, pressure, air parcel
Since air moves from high to low pressure, low pressure systems have wind from all around traveling towards it. This would push the air parcels at the low pressure systems higher than usual, lead to more energy transfer, more condensation and more precipitation.
When water gains energy, it ____(1)_____, and becomes ____(2)______, and rises into the troposphere. As the air parcel rises, it ___(3)____ energy to the surrounding air and cools. As the air parcel cools, it ______(4)_______ and becomes a ____(5)_____. A cloud is water, in the form of a ____(6)_____. If enough condensation occurs, the cloud gets heavier and heavier and eventually _____(7)_____ will occur.
1. evaporates
2. water vapor
3. loses/transfer
4. condenses
5. cloud/liquid
6. liquid
7. precipitation
