Weather & Climate: Time Scales and Comparisons — Practice · Grade 6 Science

Chapter: Water, Air, Weather & Climate

What this practice covers

By the end of Weather & Climate: Time Scales and Comparisons you should be able to:

8 questions, written answer and multiple choice, each with a worked explanation.

Vocabulary used: climate, variation, evidence, system boundary, uncertainty.

Problem 1

Does a week’s record establish a region’s long-term climate?
Answer and explanation

No. It samples short-term conditions; a long-term pattern needs a suitable much longer record.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 2

What does the common mean leave out?
Answer and explanation

The first set varies from 10 to 30 while the second varies from 18 to 22. Spread is additional information.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 3

Which conditions should be checked?
Answer and explanation

Season, site, exposure, timing, instrument method, and the interval represented by each record.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 4

Why can a cold event coexist with warming?
Answer and explanation

A changing average does not eliminate day-to-day variation or seasonal differences; one event does not represent the whole distribution.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 5

Develop a complete response: Describe the change and distinguish it from tomorrow’s weather or a cause claim. Include relevant evidence and one method or model limit.
Answer and explanation

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.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 6

Apply the unit independently: A single snowstorm is used to say a long-term temperature trend cannot exist. What scale distinction is missing? Give a reason and a relevant qualification.
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.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 7

Which statement correctly uses climate in Weather & Climate: Time Scales and Comparisons?
  1. climate: Long-term patterns and distributions of atmospheric conditions in a region.
  2. A single weather event proves or disproves a whole long-term climate trend.
  3. Equal average temperatures mean identical daily conditions.
  4. One illustrative result establishes every real condition and needs no further evidence.
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

Which statement correctly uses variation in Weather & Climate: Time Scales and Comparisons?
  1. A single weather event proves or disproves a whole long-term climate trend.
  2. variation: Differences among observations that a single average may not describe.
  3. Equal average temperatures mean identical daily conditions.
  4. One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation

variation: Differences among observations that a single average may not describe.

Differences among observations that a single average may not describe. 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.
