Water, Air, Weather & Climate — Chapter quiz · Science 6: Matter, Energy & Earth Systems, Grade 6
How do water, air, and energy processes connect weather with longer-term patterns? What can a matched five-day record tell us about weather, and what requires a different climate record?
Problem 1
- Every classroom model reproduces reality exactly.
- Every water particle follows one identical circular route.
- A cloud is simply a mass of visible water vapor.
- infiltration: Water entering spaces in soil or other ground material.
Answer and explanation
infiltration: Water entering spaces in soil or other ground material.
Water entering spaces in soil or other ground material. 35 + 25 + 20 = 80 mm, so the listed terms match the input under the model. Increased storage is not an outgoing flow. If unrecorded groundwater entered or left, the account would need that transfer; balance here does not prove every real pathway was measured.
Problem 2
Answer and explanation
No. Runoff, groundwater flow, evaporation, and other routes can bypass plant uptake. Show alternatives rather than one compulsory route.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 3
- weather: Atmospheric conditions at a particular place over a relatively short interval.
- A forecast is a guaranteed observation of the future.
- A noon temperature record automatically gives the whole day’s maximum.
- Every classroom model reproduces reality exactly.
Answer and explanation
weather: Atmospheric conditions at a particular place over a relatively short interval.
Atmospheric conditions at a particular place over a relatively short interval. Noon temperature decreases from 19 to 15 °C across the three records. Pressure drops to 1,006 hPa on the rainy day and rises afterward. This small table is consistent with changing weather, but it does not prove pressure alone caused rain, give daily maxima, or establish a rule for every storm.
Problem 4
Answer and explanation
Use the supplied weather records or safe indoor observations approved by a parent. Better notes do not require exposure to hazardous weather.

Problem 5
- Air has no mass because it is invisible.
- air pressure: Force per area associated with air’s interactions and atmospheric conditions.
- Uneven heating determines every wind direction without other influences.
- Every classroom model reproduces reality exactly.
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. The difference is 12 hPa. The simplified model predicts air responding from A toward lower-pressure B. This is not an exact real-wind forecast, because the actual path also depends on rotation, friction, terrain, and surrounding pressure patterns. Pressure is a comparison, not a cause inferred from one unlabeled arrow.
Problem 6
Answer and explanation
No. The same amount can occupy a larger volume in a flexible boundary. State the container conditions before inferring an amount change.

Problem 7
- Equal average temperatures mean identical daily conditions.
- A single weather event proves or disproves a whole long-term climate trend.
- climate: Long-term patterns and distributions of atmospheric conditions in a region.
- Every classroom model reproduces reality exactly.
Answer and explanation
climate: Long-term patterns and distributions of atmospheric conditions in a region.
Long-term patterns and distributions of atmospheric conditions in a region. The supplied summaries rise by 0.8 °C from first to last. They describe a regional seasonal pattern across the stated periods, not tomorrow’s temperature. The numbers alone do not identify the cause or describe every location, and daily variation remains within each period.
Problem 8
Answer and explanation
An event is short-term weather, while the trend concerns a distribution across many years. Evaluate the long-term evidence directly instead of replacing it with one selected event.

Problem 9
- Every classroom model reproduces reality exactly.
- The atmosphere is a perfectly sealed roof that blocks all outgoing energy.
- A classroom jar or one trend graph proves every cause and policy conclusion.
- mitigation: Reducing causes or drivers of a problem, such as greenhouse-gas emissions in a climate response.
Answer and explanation
mitigation: Reducing causes or drivers of a problem, such as greenhouse-gas emissions in a climate response.
Reducing causes or drivers of a problem, such as greenhouse-gas emissions in a climate response. The shade plan addresses exposure adaptation but exceeds the five-token limit. The redesign fits the cost condition and targets energy use; any emissions benefit would depend on the energy source and other information. A 3 °C change and 20 energy units are different quantities and cannot be added as one score. The records are illustrative, not a tested policy or a required preference.
Problem 10
Answer and explanation
No. A jar also changes convection and other conditions. It can illustrate selected energy ideas, but a full atmospheric explanation needs appropriate radiation evidence and explicit model limits.
