Air, Pressure & Uneven Heating — Drills · Grade 6 Science
Chapter: Water, Air, Weather & ClimateWhat these drills covers
By the end of Air, Pressure & Uneven Heating you should be able to:
- I can explain what causes atmospheric pressure and why it falls with height.
- I can explain how uneven heating produces a pressure difference and therefore wind.
- I can describe how a sea breeze forms and why it reverses at night.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: air pressure, circulation, evidence, system boundary, uncertainty.
Problem 1
- A sample with missing measurements has proved those values are zero.
- Air has no mass because it is invisible.
- Uneven heating determines every wind direction without other influences.
- air pressure: Force per area associated with air’s interactions and atmospheric conditions.
Answer and explanation
air pressure: Force per area associated with air’s interactions and atmospheric conditions.
Force per area associated with air’s interactions and atmospheric conditions.
Problem 2
- circulation: A connected pattern of fluid movement with exchange and return pathways.
- Uneven heating determines every wind direction without other influences.
- Air has no mass because it is invisible.
- Repeating any method makes every causal claim true.
Answer and explanation
circulation: A connected pattern of fluid movement with exchange and return pathways.
A connected pattern of fluid movement with exchange and return pathways.
Problem 3
Answer and explanation
It helps account for moving air and makes the circulation model coherent instead of showing air accumulating indefinitely.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
No. Rotation, friction, terrain, and the larger pressure pattern can alter the actual flow.
