Air Masses Collide – Earth’s Atmosphere Section 3.1
In class each pair had the opportunity to observe the effects of cool air mass and lar air masses meeting.
In general the results were ver good based on the following procedure and chages that I note below:
Remember that we added clay to the materials list to
help form curved edges that match the beaker.
~10mL of salt with 40mL of COLD water
RESULTS AFTER PULLING CARDBOARD STRAIGHT UP:
Notice the angle of the
photo and how the blue
stand out more here
RED
BLUE
~40mL of HOT water
You want your beaker
to be split in half with a
left and right side
before allowing the two
liquids to collide
This picture was taken looking directly
at the side of the beaker, showing a clear
division of red on top and blue on bottom
What’s the Point?
THE TWO LIQUIDS MODEL AIR MASSES VERY WELL BECAUSE THE DENSE SUBSTANCE WILL MOVE
DOWN AND SUBSTANCE THAT IS LESS DENSE WILL MOVE UPWARD, JUST AS AIR MOLECULES DO.
