Review: Land, Water and Surface Change
Distinguish Earth features and fast or slow changes.

Use the skills in a new task
Draw or write four parts for “Land, Water and Surface Change”—one pretend example from each lesson. In each part, show what happened, give your answer, and say which clue helped you. If the question gives numbers, show your working too. Finish with one thing the practice case does not tell us. You may say your answers aloud.
Work on paper or in your own document. Explain the choices you made.
- Choose one pretend example from each of the four lessons.
- Name what each example shows.
- If the example gives numbers, show your calculation and unit. Otherwise, say which clue explains your answer.
- Say that the case details are supplied for practice; they are not your own real-life observations.
- Say one thing the example does not tell us, or one change that could give a different answer.
Compare with a model response
Panel 1: Which scientific label fits the specifically described step or feature? Supplied case: Long flowing channel. Result: river. Reasoning: The answer is river. In the notes, it means “flowing water channel.” Maps represent selected features. A river is flowing surface water; a lake is a body of water surrounded by land. A map’s color key defines how features are drawn. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Which scientific label fits the specifically described step or feature? Supplied case: Rock splits into smaller pieces. Result: weathering. Reasoning: The answer is weathering. In the notes, it means “rock breaks into smaller material.” Weathering breaks down rock. Erosion moves rock or sediment; deposition leaves it in a new place. Several processes can occur in the same landscape. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 3: Which scientific label fits the specifically described step or feature? Supplied case: Slope collapses within a minute. Result: rapid. Reasoning: The answer is rapid. In the notes, it means “change described over seconds or minutes.” The timescale matters. Earth changes can occur quickly or accumulate gradually. Use the stated intervals, not a guess from how dramatic a picture looks. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 4: Which scientific label fits the specifically described step or feature? Supplied case: Need to reduce loose soil loss. Result: plant cover. Reasoning: The answer is plant cover. In the notes, it means “roots and cover can help retain soil.” A solution should address the process causing damage. These paper proposals are simplified models. Real flooding or slope hazards require qualified local advice. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified.
A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
