Density
What is the equation for density?
D=m/v
What does a meteorologist study?
Weather
What are the permanent gases in our atmopshere?
Nitrogen and Oxygen
Which process allows plants to help make the atmosphere better for humans?
Photosynthesis
Which units do we use for atmospheric pressure so we notice small differences?
millibar
What are the units for mass?
g
What is a tornado?
A rapidly rotating column of air that extends from the thunderstorm to the ground
What are the percentages of each permanent gas in our atmosphere?
78% Nitrogen and 21% Oxygen
What goes into photosynthesis?
Water, Carbon Dioxide and Sunlight
Why does weather happen in the troposphere?
Air is more dense in the troposphere
What are the units for volume?
mL
What is a hurricane?
A storm that rotates around a low pressure system or an eye
Why are some gases variable in our atmosphere?
It depends on the activities of humans on Earth
What goes out of photosynthesis?
Oxygen and Sugar
Between which two places on Earth is it the hottest?
Between the Tropic of Cancer and the Tropic of Capricorn
What would the density of an object be if it had a mass of 30g and a volume of 10mL? Show all work and hand in to the teacher. Write this on a post-it
3g/mL
What happens when humidity is 100%?
Precipitation (it rains)
Why is it harder to breathe on top of a mountain compared to the bottom of the mountain?
Air is less dense
What causes wildfires to happen?
A drought and wind that can make it spread
What is thunder?
The sound made from gas expanding from lightning.
What would the density of an object be if it has a mass of 18g and a volume of 9mL? Show all work and write this on a post-it to receive full credit.
2g/mL
What causes lightning?
Electrical charge from the thunderstorm to the ground
Why do planes fly in the stratosphere?
They ant to use the jet streams and the air is less dense than the troposphere
If humans remove forests, how does that affect the carbon dioxide and oxygen in the atmosphere?
There would be more carbon dioxide and less oxygen
How does air move in a Hadley Cell? Draw a picture if it helps you explain it.
Warm air rises since it is less dense. Then it cools and sinks since it is more dense. Then it gets replaced by new air and then heats up again.
