Air-ology
This is the most abundant gas in the air, making up approximately 78% of its composition.
Nitrogen
This force pulls everything toward the earth due to gravity
What is Weight?
Hot air rises because its molecules are more spread out, which makes the air this.
What is less dense?
Aviation is considered the fastest way for travelers to cross this.
What is the ocean?
Airplanes output large amounts of this gas, which is known for causing climate change and global warming.
What is carbon dioxide (CO2)?
his property allows air to be squeezed together, a process often used to inflate bicycle tires.
Compression
This English inventor and aviator was the first to identify the four main forces of flight.
This was the year the first human-carrying hot air balloon was invented.
What is 1783?
These aircraft have large fuselages used specifically for importing and exporting goods like clothing and food.
What are cargo planes?
This health issue has been correlated specifically with airport noise pollution.
What is high blood pressure?
This happens to air pressure the higher you go into the atmosphere.
decreases
This force is caused by air resistance and acts against thrust.
What is Drag?
A pilot does this to the burner's flame to make the balloon descend.
What is reduces the heat?
These vehicles are used in health care to airlift injured people to hospitals quickly.
What are helicopters?
Aircraft engines can be extremely noisy, sometimes exceeding this many decibels.
What is 140 decibels?
These move more quickly when air is heated
What are air particles?
This force moves an object forward and can be provided by muscles, engines, or gravity.
Unlike hot air balloons, these stay airborne because they are naturally lighter than the surrounding air.
What are helium balloons?
This is one environmental benefit of aviation related to agriculture.
What is watering crops or spraying fertilizer?
International air travel can be a cost to safety because it allows for the transport of these two harmful things between countries.
What are diseases and invasive species?
Air is primarily made of these three gases
What are Nitrogen, Oxygen, and Argon?
For a plane to fly, this force must be greater than weight.
What is Lift?
This is the location of the burner on a hot air balloon.
What is directly below the bottom of the balloon?
These are three examples of jobs provided by the aviation industry.
What are pilots, flight attendants, traffic controllers, luggage handlers, or travel agents?
Besides ticket prices, these are two other major financial costs of aviation.
Building new airplanes and repairing them
