Study Notes
Question 13 Analysis
- A team of engineers wants to identify hard, solid rock beneath the surface in the Indian Ocean and Sri Lanka.
- Option A suggests rock exists under both locations, citing the entire Earth's outer layer as hard, solid rock.
- Option B states that only under Sri Lanka (a continent) is there hard rock.
- Option C explains that water is present under both areas, which would inhibit drilling for rock.
- Option D claims the presence of sand and gravel prevents rock discovery.
