Moving Plates, Boundaries & Earth Evidence — Drills · Grade 6 Science
Chapter: Earth Systems, Plates & Earth MaterialsWhat these drills covers
By the end of Moving Plates, Boundaries & Earth Evidence you should be able to:
- I can describe the three kinds of plate boundary and what happens at each.
- I can use the global pattern of earthquakes as evidence for plate boundaries.
- I can explain how magnetic stripes on the sea floor record plate movement.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: plate boundary, subduction, evidence, system boundary, uncertainty.
Problem 1
- A boundary map predicts the exact time of the next earthquake.
- Every coastline is necessarily a plate boundary.
- plate boundary: A region where tectonic plates interact through relative motion.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
plate boundary: A region where tectonic plates interact through relative motion.
A region where tectonic plates interact through relative motion.
Problem 2
- Repeating any method makes every causal claim true.
- A boundary map predicts the exact time of the next earthquake.
- Every coastline is necessarily a plate boundary.
- subduction: One lithospheric plate sinking beneath another at a suitable convergent boundary.
Answer and explanation
subduction: One lithospheric plate sinking beneath another at a suitable convergent boundary.
One lithospheric plate sinking beneath another at a suitable convergent boundary.
Problem 3
Answer and explanation
A relationship between seismic activity and a boundary region, not an exact earthquake prediction.
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
It marks land meeting water, not necessarily a change between moving lithospheric plates.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
