Homework Check
Questions page A 464) Would you expect the air pressure in a valley that’s
below sea level to be higher or lower than air pressure at sea level? Explain.
6) The eardrum is a thin sheet of tissue that separates air in the middle part of our ear from air outside your ear. What could cause your eardrum to make a popping sound as you ride up a tall building in an elevator?
How did you do?
Answers to questions:4) Air pressure would be higher in the valley because
air pressure decreases as altitude increases.
6) The higher pressure inside the ear pushes the eardrum outward as the air pressure in the elevator decreases.
Combination Notes
In your notebook or a word document create a 2-column chart for notes and pictures.
Read the title and first subheading from section 2.1 in your textbook p. A43.
Then summarize the section by writing 4 key points in bullet format in your own words (don’t copy word-for-word from text).
Combination notes
Summarizing
Read the rest of the pages about air pressure. Summarize each section by writing at least 4 key points in bullet format in your own words (don’t copy word-for-word from textbook.) Section 2.1 The Atmosphere’s air pressure changes• Air exerts pressure• Air pressure is related to altitude and
density• Pressure and Air Motion• Barometers and Air Pressure
McDougall Text p. 44A
Summarizing
Read the pages about wind patterns. Summarize each section by writing at least 4 key points in bullet format in your own words (don’t copy word-for-word from textbook.) Pages A 47-48 & 53 Section 2.2 The Atmosphere has wind patterns.• Uneven heating causes air to move.• Patterns of heating and cooling cause
local winds• Local winds
McDougall Text p. A53
How wind forms
McDougall Text p. A48
Air moves from high pressure toward low pressure
Temperature differences create
pressure differences which produce wind.
