If atmospheric pressure is high, is the density high or low?
high
What way does wind move?
From areas of high pressure to areas of low pressure
What is water in the gas form called?
Water vapor
What tool is used to measure air pressure?
barometer
Describe the density of cold air compared to warm air.
Cold air is more dense than warm air
Why is atmospheric pressure lower at the top of a mountain than it is at sea level?
At higher altitudes, there is less particles (less weight/pressure)
Give one way wind affects the biosphere.
Birds fly, it can break trees, Wind makes us feel colder ...
How do plants contribute to the water cycle?
Transpiration- plants release water vapor through the air.
What does an anemometer measure
Wind Speed
Describe the "path" or direction water travels in the water cycle.
Water changes state from liquid, solid, and vapor through the different processes. There is no exact "direction"
Why is density of air greater at the surface of earth than on a mountain?
Gravity pulls heavier gasses and particles down
Areas of high and low pressure are connected by a circular pattern of air flow called____________
Convection cells or convection currents
What happens to water vapor as it rises higher in the atmosphere?
It cools and condenses, turning back to liquid
What units are used for absolute humidity?
g/m3
When does dew form?
When the relative humidity is 100%
or when the temperature reaches the dew point
What type of weather could you expect on a day with very high pressure?
Clear, calm, dry
Name the wind that Denver is experiencing.
North Westerly Wind
Where does water collect after it falls as precipitation (name 3)?
Rivers, lakes, oceans, groundwater, puddles
What is the name of the scale that helps us understand the effects of wind speeds on objects outdoors?
Beaufort Scale
What type of cloud can produce thunderstorms and tornadoes
cumulonimbus clouds
This is what happens to air molecules when air pressure increases.
They get closer together (pressure increases)
What effect would increasing the difference in air pressure have on a region?
strong winds
What 3 processes of the water cycle are driven by GRAVITY?
What is the name of the tool used to measure precipitation?
rain guage
A scientist measures an atmospheric pressure of approximately 995 millibars at an elevation of 153 meters. What would happen if the scientist took the reading at sea level?
the pressure would be higher at sea level
