Cloud Formation

What are the ingredients necessary for a cloud to be created?

• wind, heat, water
• dust, water vapor, low pressure
• cool temperatures, water, vapor
• high pressure, water, wind

What prevents cloud formation?

• High pressure
• warm temperature
• wind
• Low pressure

How do you create high air pressure inside a capped plastic bottle?

• squeeze the bottle and let go
• cool the bottle
• remove the air inside the bottle
• squeeze the bottle

How do you decrease the pressure inside a bottle model for cloud formation?

• squeeze the bottle
• turn the bottle upsidedown
• shake the bottle
• squeeze the bottle then let go

Why do you need a plastic bottle to create a cloud?

• It is clear
• You can recycle it
• It is flexible
• It is not fexible

What happens to cloud formation when air pressure rises (high pressure)?

• amount of clouds decreases
• amount of clouds increases
• clouds scatter
• clouds come together

How are air (atmospheric) pressure and cloud formation related?

• Air pressure has no affect on cloud formation
• When air pressure expands,  cloud formation increases
• Higher air pressure increases cloud formation
• Low air pressure increases cloud formation

When the weather gets cloudy, that's a good sign that _____________________

• Higher air pressure is coming in
• Temperatures are going up
• Temperatures are moving down
• Lower air pressure is coming in

If atmospheric pressure increases, clouds will __________________________

• give rain
• increase
• go away
• produce snow

What three ingredients must you add to a cloud formation bottle model to create a cloud? 

• dust, water vapor, and low air presssure
• dust, water vapor and high air pressure
• water droplets, low air pressure, and heat
• coolness, dust and low pressure
