The Diagram Below gives information about the Hawaiian Islands chain in the centre of the Pacific Ocean.
Sample Response
The picture depicts information about the Hawaiian Islands chain, situated in the middle of the Pacific Ocean.
Overall, the Hawaiian island is the largest among the Islands of the Pacific Ocean, comprising some ancient volcanoes. However, the movement of tectonic plates to the western side of the Ocean each year causes several volcanic activities.
The Hawaiian island is the largest among the eight islands of the Pacific Ocean, with some tiny islands such as Nihau also being found in the Ocean. The Pacific Ocean experiences tectonic plate movement drifting apart around 7 to 9cm each year. This has resulted in many volcanoes being formed in one of the major islands, the Hawaiian Islands.
As illustrated in the diagram, Hawaiian Island had suffered major volcanic eruptions, with the oldest dating back some 80million years ago. The volcanic eruption process begins to form some 2883km below the solid, dense rock. Eventually, a spume is formed, which remains immobile on the Hot spot. Until tectonic plates drift to the north-western angle of the ocean some 7 to 9 centimetres, magma spume flows through the solid, dense rock, initiating another volcanic activity.
IELTS Writing Correction
- 1. Limit the comparison Original: the largest among the Islands of the Pacific Ocean Suggested revision: the largest of the eight major islands shown Why it matters: The diagram supports a comparison within the depicted chain, not with every island in the Pacific.
- 2. Clarify chain formation Original: comprising some ancient volcanoes Suggested revision: and the chain contains volcanoes of different ages Why it matters: The age pattern applies across the island chain rather than only to Hawaii.
- 3. Correct the direction Original: to the western side of the Ocean Suggested revision: towards the northwest Why it matters: The arrows show the Pacific plate shifting northwest.
- 4. Describe the result Original: causes several volcanic activities Suggested revision: creates successive volcanoes above the fixed hot spot Why it matters: The diagram shows repeated volcano formation as the plate crosses a stationary hot spot.
- 5. Fix tense and form Original: Hawaiian Island had suffered Suggested revision: the Hawaiian island chain has experienced Why it matters: The present-perfect form and full noun phrase correctly describe the chain's history.
- 6. Avoid unsupported scale Original: major Suggested revision: successive Why it matters: The visual shows numerous eruptions but does not classify them as major.
- 7. Remove time redundancy Original: dating back some 80million years ago Suggested revision: dating back about 80 million years Why it matters: Using both "dating back" and "ago" is redundant.
- 8. Fix verb structure Original: The volcanic eruption process begins to form Suggested revision: The eruption process begins Why it matters: A process begins at a location; it does not itself begin to form.
- 9. Format the depth Original: some 2883km below Suggested revision: about 2,883 km below Why it matters: The diagram labels the origin as approximately 2,883 kilometres below the surface.
- 10. Use precise terminology Original: a spume is formed Suggested revision: a magma plume rises Why it matters: A rising magma plume expresses the process more accurately and naturally.
- 11. Clarify the hot spot Original: remains immobile on the Hot spot Suggested revision: remains stationary above the hot spot Why it matters: The diagram indicates that the plume stays fixed while the plate moves.
- 12. Show simultaneous action Original: Until tectonic plates drift Suggested revision: As the Pacific plate drifts Why it matters: The volcano-forming process occurs as the plate moves, not only until it moves.

Why this response received Band 5.5
The response is clearly organised and communicates the basic relationship between plate movement, the stationary hot spot, and volcanic formation. Its main limitation is Task Achievement: it misplaces the oldest volcano on Hawaii, describes the plate as drifting apart or westward rather than shifting northwest, and does not clearly explain that island age increases away from the youngest volcano. Prioritise an accurate overview of this sequence before adding details.
IELTS Writing Criteria Scores
Task Achievement
The response identifies the plate, hot spot, magma plume, movement rate, and depth, but its overview and several details misrepresent the chain's formation and age pattern.
State that the Pacific plate shifts northwest 7–9 cm annually over a fixed hot spot, creating the youngest volcano at Hawaii and progressively older volcanoes to the northwest.
Coherence and Cohesion
Four purposeful paragraphs and clear sequencing make the description easy to follow, although repetition and an awkward final sequence weaken progression.
Organise the details as one continuous cause-and-effect sequence and avoid repeating the claim that Hawaii is the largest island.
Lexical Resource
Relevant geological vocabulary is attempted, but imprecise or unnatural choices such as “volcanic activities,” “drifting apart,” and “north-western angle” reduce accuracy.
Use precise process terms such as “plate shifts,” “magma plume rises,” “eruption occurs,” and “island chain forms.”
Grammatical Range and Accuracy
The response uses a mixture of simple and complex structures, but recurring article, agreement, tense, and clause-control errors reduce grammatical reliability.
Check subject–verb agreement and construct time clauses completely, especially when describing what happens as the plate moves over the hot spot.
