Weather
What is weather?
A specific event---like a rainstorm
True or false: air is made of particles too small to see
True. We can't see air.
In which layer of the atmosphere do meteors burn up? Shooting stars are also seen here.
Mesosphere
Which is heavier: gold or feathers?
They are the same in weight
What is radiation?
the transfer of heat energy through empty space
What is meteorology?
The study of weather
True or false: Air is in many places, but not in closed containers
False. Air is everywhere!
This layer of the atmosphere is closest to us. Weather happens here. It is also the thinnest layer.
Troposphere
Say you have two cups filled with different items (cotton balls and sand). The cup of sand weighs more than the cup of cotton balls. Why?
The sand is more dense than the cotton balls
What is conduction?
The transfer of heat energy through materials
What is climate?
Average weather conditions over a long period of time
True or false: air takes up space
True
This layer of the atmosphere gradually becomes space. What layer is it?
Exosphere
Think back to the 4 different colors of water experiment. What did you learn about density? How did density play a role in the layering phenomena?
The most dense liquid was at the bottom
What is one example of conduction?
-Getting burned by taking the cookies out of the oven and not using oven mittens
-touching a hot metal spoon that's been sitting in boiling water
Bonus!!! Extra 100 points + 400 points
Woohoo!
True or false: air is made up of two gases--oxygen and carbon dioxide
False! It is made of nitrogen, oxygen, and argon: water vapor, CO2, ozone, and other gases
This layer experiences the hottest temperatures and is the thickest layer (is 85-560km long). What layer is it?
Thermosphere
What is convection?
the transfer of heat through a fluid (liquid or gas)
What is one example of radiation?
-getting sunburned
-microwaving ramen
Why is weather different in different places around the world?
-sun's rays hit at different angles
-closer to the equator = warmer weather
-latitude plays a role
What happens to air when it is pushed into a smaller space?
Compressed
This layer contains a layer of ozone (high-energy UV rays). What layer is it?
Stratosphere
What role does heat play in the layering phenomena? Think back to the blue ice cube and red hot water experiment.
Heat rises, which means it is less dense than cool temperatures.
What is one example of convection?
-hot air balloon
-air conditioner
-boiling water --- the hot water touches the cold water and warms it up
-fridge
