Rocks, Weathering & the Rock Cycle — Drills · Grade 6 Science
Chapter: Earth Systems, Plates & Earth MaterialsWhat these drills covers
By the end of Rocks, Weathering & the Rock Cycle you should be able to:
- I can name the three rock groups and how each one forms.
- I can read cooling rate from the crystal size in an igneous rock.
- I can distinguish weathering from erosion and give an example of each.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: weathering, erosion, evidence, system boundary, uncertainty.
Problem 1
- weathering: Breakdown or alteration of material in place.
- The rock cycle forces every rock through one fixed sequence.
- Metamorphism requires complete melting of the rock.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
weathering: Breakdown or alteration of material in place.
Breakdown or alteration of material in place.
Problem 2
- Metamorphism requires complete melting of the rock.
- erosion: Transport of material by agents such as flowing water, wind, ice, or gravity.
- The rock cycle forces every rock through one fixed sequence.
- Repeating any method makes every causal claim true.
Answer and explanation
erosion: Transport of material by agents such as flowing water, wind, ice, or gravity.
Transport of material by agents such as flowing water, wind, ice, or gravity.
Problem 3
Answer and explanation
Its stated formation pathway includes solidification from melt, which is igneous; classification follows the relevant process.
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. The model has alternatives governed by conditions; time spent on each pathway also varies.
