This is the thin envelope of gases that surrounds a planet
What is the atmosphere
100
This is the definition of density
What is the amount of matter (particles) in a given volume (space) of air
100
This is the most abundant gas in the atmosphere
What is Nitrogen
100
This is the formula for Density
What is Density=mass/volume
200
This current affects (warms/cools) the air above it
What are surface currents
200
What gases make up Earth's atmosphere?
What is Nitrogen, Oxygen, Carbon Dioxide, Water Vapor and other trace gases such as Argon
200
This is the force that pushes on an area or surface
What is air pressure
200
This gas at around 1% is also known as a Greenhouse Gas
What is Carbon Dioxide
200
This is the force that causes currents to curve
What is the Coriolis effect
300
This current affects climate
What are surface currents
300
This instrument is used to measure air temperature
What is a thermometer
300
This is the distance above sea level
What is altitude
300
This gas is only present in wet air
What is water vapor
300
This is the direction currents curve in the southern hemisphere
What is counterclockwise
400
This causes deep ocean currents
What is changes in water's density?
400
This is the term used to describe water as an invisible gas
What is water vapor
400
This is why air pressure doesn't crush you.
What is molecules push in all directions
400
This term is used to describe the condition of Earth's atmosphere at a particular place and time
What is weather
400
The properties of air include __________ and ____________ and are affected by ______________.
What is density, pressure, and altitude
500
This is why deep ocean currents are important
What is deep ocean currents mix water around the world- spreads oxygen that marine life requires
500
This instrument is used to measure air pressure
What is a barometer
500
This is the relationship between altitude, density and air pressure.
What is as altitude increases, the density of air and the pressure decreases. As altitude decreases, the air becomes more dense and the pressure increases.
500
This is the composition of the atmosphere
What are gases such as Nitrogen, Oxygen, Carbon Dioxide, water vapor, and other trace gases along with particles such as dust, smoke, salt, and chemicals
500
This is how the metal can was crushed in our demonstration
What is heated air is less dense, so when can was removed from heat source and lid placed on top, less dense, hot air was trapped inside, more dense cold air could not get in to equalize the pressure, so the more dense cold air squeezed the can until the volume inside match the lower density and pressure inside the can and out were equal.
