Inside Earth: Layers & Indirect Evidence — Drills · Grade 6 Science
Chapter: Earth Systems, Plates & Earth MaterialsWhat these drills covers
By the end of Inside Earth: Layers & Indirect Evidence you should be able to:
- I can explain how earthquake waves reveal what Earth is made of.
- I can explain why the inner core stays solid although it is hotter than the outer core.
- I can distinguish layers defined by composition from layers defined by how they behave.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: lithosphere, indirect evidence, evidence, system boundary, uncertainty.
Problem 1
- The entire mantle is a liquid ocean.
- lithosphere: The rigid outer layer including the crust and uppermost mantle.
- The crust and the whole lithosphere are identical layers.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
lithosphere: The rigid outer layer including the crust and uppermost mantle.
The rigid outer layer including the crust and uppermost mantle.
Problem 2
- The entire mantle is a liquid ocean.
- The crust and the whole lithosphere are identical layers.
- indirect evidence: Observations used to infer a feature that is not directly inspected.
- Repeating any method makes every causal claim true.
Answer and explanation
indirect evidence: Observations used to infer a feature that is not directly inspected.
Observations used to infer a feature that is not directly inspected.
Problem 3
Answer and explanation
No. It is evidence to interpret with geometry, multiple stations, and other records rather than a complete map by itself.
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
Only if it is explicitly to scale. Otherwise it illustrates order and relationships rather than exact dimensions.
