nitrogen and oxygen
nitrogen and hydrogen
carbon dioxide and nitrogen
carbon dioxide and oxygen

• Q4
Ozone is
a form of nitrogen with three nitrogen atoms in each molecule
a form of nitrogen with two nitrogen atoms in each molecule
a form of oxygen with the three oxygen atoms in each molecule
a form of oxygen with two oxygen atoms in each molecule

• Q5
Water vapor is water in the form of
crystals
steam
a gas
droplets
60s
• Q6
Earth's atmosphere is important to living things because it
contains dust and other particles
provides all the gases that living things need to survive
is very thin compared to the size of the Earth
maintains a constant relative humidity
60s
• Q7
Earth's atmosphere traps energy from the sun, which
allows solar radiation to penetrate to the surface
allows ozone to form easily
allows water to exist as a liquid
causes meteors to burn up
60s
• Q8
Air has pressure because
temperature warms the air
air has mass
wind moves the air
the stratosphere is thick
60s
• Q9
Density can be determined using the formula
density = mass x volume
density = mass/volume
density = volume/mass
density = mass + volume
60s
• Q10
The less mass in a given volume of air, the
more dense the air
more the air weighs
greater the air pressure
less dense the air
60s
• Q11
Instruments used to measure air pressure are called
hygrometers
thermometers
barometers
hydrometers
60s
• Q12
An aneroid barometer is different from a mercury barometer in that it
does not contain a liquid
provides readings that increases as air pressure increases
measures temperaure
60s
• Q13
The air pressure acting on the roof of your house
comes from the air within a few feet of your rooftop
is much greater underneath your roof than on top of it
is much greater on top of the roof than below it
comes from all the air above your roof
60s
• Q14
As you rise upwards in the atmosphere, air pressure
increases
first increases, then decreases
doesn't change
decreases
60s
• Q15
When climbing a high mountain, you get out of breath easily because
there is more oxygen in the air.
there is less oxygen in each cubic meter of air
the air is more dense
air pressure is greater
