8.3-8.4 Notes Flashcards
What is the driving force of the water cycle
Suns energy
As the water evaporates what increases
Humidity
What type of air holds more water and what type of air holds less water
More: hot
Less:cold
The amount of water vapor present in the air is dependent on
The amount of water vapor that has been evaporated
The amount of water vapor in the air can possibly hold is totally dependent on
The temperature of the air itself
Direct proportion
As the temperature of the air increases the amount of water vapor that the air can hold will also increase
Relative humidity formula
Present air humidity/saturated air humidity and times 100
What determines the dewpoint
Relative humidity
Define dew point
The temperature at which air must cool to be saturated
Air temp dropping below the dew point causes what to form
Clouds
How does snow form
When temperatures are cold that water vapor changes to solid
Where does hail form
Cumulonimbus clouds
Rain gauge
Measures precipitation
Air mass areas are called
Source regions
When 2 masses meet what forms
A front
And high pressure areas what happens to the air
Descends and doesn’t form clouds
What happens in low pressure areas
Air rises and cools and makes clouds
What controls the movement of storms
Jet stream
What causes flash flooding 🔥
Runoff
Most powerful storms on earth🔥
Hurricane
Why don’t hurricane form at higher latitudes🔥
Water is too cold
How does a hurricane form🔥
Thunderstorm that splits by winds causing the storm to spin
Where do hurricane get there energy 🔥
Condensation of water vapor
In a hurricane what is around the eye🔥
Eye wall
In a hurricane what had the strongest winds 🔥
Eye wall
In a hurricane what does the most damage🔥
Storm surge
What is a storm surge🔥
A rise in local sea level near the shore due to strong winds from the hurricane
Angle of the sun during summer and winter🔥
Summer: 90°
Winter: less then 45°
Differential heating of the earth by the sun creates🔥
Convection
Cold front and example
Cold air moves under warm air
Thunderstorms
Warm front and example
Warm air moves over cold air
Rain
Occluded front and example
Warm air is caught between 2 cold air masses
Snow
Stationary front and example
Cold front meets warm front but is too weak to move it
Maybe rain
What can low pressure bring
Rain
What does high pressure bring
Light winds and blue sky’s
How do low pressure and high pressure look like
Low pressure
High pressure
Why does low pressure systems bring bad weather
As air rises, it moistens bringing rain
Why do high pressure systems bring good weather
Sinking air means the drying of air
How much is earth tilted in its axis
23.5 degrees
