Earth’s Spheres & System Interactions — Drills · Grade 6 Science
Chapter: Earth Systems, Plates & Earth MaterialsWhat these drills covers
By the end of Earth’s Spheres & System Interactions you should be able to:
- I can name the four Earth systems and give an example of each.
- I can trace a single water molecule or carbon atom across more than one system.
- I can explain why the boundaries between the systems are chosen rather than found.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: geosphere, biosphere, evidence, system boundary, uncertainty.
Problem 1
- geosphere: Earth’s rocky material, landforms, and interior in a system model.
- Earth’s spheres are independent sealed boxes.
- Every arrow in a system model represents the same kind of transfer.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
geosphere: Earth’s rocky material, landforms, and interior in a system model.
Earth’s rocky material, landforms, and interior in a system model.
Problem 2
- Every arrow in a system model represents the same kind of transfer.
- biosphere: Living organisms and their biological relationships within Earth’s systems.
- Earth’s spheres are independent sealed boxes.
- Repeating any method makes every causal claim true.
Answer and explanation
biosphere: Living organisms and their biological relationships within Earth’s systems.
Living organisms and their biological relationships within Earth’s systems.
Problem 3
Answer and explanation
They explain different quantities and processes. An unlabeled single arrow can blur material transport with the energy driving it.
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. It suggests a mechanism to investigate, but numerical prediction needs site conditions and measurements.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
