The response covers all seven stages and gives an overview. Some relationships are imprecise: winds are said to generate moist air, and rainfall is described as heavy without a stated intensity. The thousands-of-kilometres scale is present in the diagram, but the essay should relate it to geographical locations rather than to moist and dry air.

The progression of stages is broadly clear with sequencing devices like 'subsequently' and 'following this', but cohesion is mechanical, reference is sometimes unclear, and sentences repeat 'process' and 'subsequent' awkwardly.

The response uses adequate topic-related vocabulary such as 'windward side', 'leeward side', and 'moisture', but frequent spelling errors like 'porcess', 'begining', 'swirched', and 'kilometeres' and imprecise word choices reduce its range and accuracy.

A mix of simple and complex structures is attempted, yet errors are frequent, including 'winds including moisture approach coast', 'rised become cool', and 'go to downwards', which sometimes obscure meaning.

The response follows all seven stages and includes an overview and the distance scale. However, describing winds as transforming into moist air and droplets as changing into dry air misrepresents the process: moist air rises and cools, rain falls, and dry air continues over the mountain.

The stages progress logically with clear sequencing devices such as 'at the first stage' and 'in the following stage', with only occasional awkward cohesion in the final paragraph.

Vocabulary is generally adequate for the process, using terms like windward, leeward and moist air, but some choices are imprecise or awkward, such as 'decreases' for descending air and 'the approaching of winds'.

A range of structures is attempted, including passives and subordinate clauses. Errors include missing articles in “to coast” and “rain-shadow desert”, the prepositions in “in the windward side” and “reaching ... to inland areas”, and the nonparallel “beginning ... to ending” construction.

All seven stages are covered in order, with a clear overview identifying moisture loss as the cause and accurate references to the windward and leeward sides. However, the scale shows the coast-to-inland distance, so it does not support the claim about the desert's size.

The response progresses logically through the process with well-managed cohesive devices such as as, consequently, by the time, and these dry winds, giving a smooth and effortless sequence.

Vocabulary is flexible and precise, including natural process language like strips moisture, parched, windward slopes, leeward side, and barren belt, with no inappropriate usage.

A wide range of complex structures, including participial and relative clauses, is used with strong control. Sentences such as 'As this moist air rises it cools' clearly express the relationships between stages.

All seven stages are covered, with a clear overview contrasting the windward and leeward sides. The distance scale is generalised as a long distance, while continued cooling after cloud formation and the absolute absence of further rainfall go beyond the explicitly labelled stages.

The process is sequenced coherently, with separate paragraphs for the windward and leeward stages and clear causal links. Some stage-opening expressions are formulaic, and placing the statement that air becomes dry after its descent slightly blurs the transition.

Vocabulary is precise and topic-appropriate, using terms such as moist air, windward, leeward, precipitation and moisture flexibly with no noticeable inaccuracy.

Complex sentences, passives and participial clauses are controlled accurately. Clauses introduced by as, while and since express time or cause, and there are no clear grammatical errors in this response.

The response covers all seven stages in accurate sequence with a clear overview of the process start and finish; only the treatment of 'thousands of kilometres' as a rainfall span rather than a distance scale slightly reduces precision.

The account progresses logically through the stages with cohesive devices such as 'Upon encountering' and 'Having lost the moisture' used naturally, showing strong control of sequencing with no visible strain.

Vocabulary is precise and naturally applied to a process, with terms like 'condensation of water vapour', 'depletes the air of its moisture', and 'devoid of moisture' demonstrating flexible, topic-appropriate usage.

A wide range of structures, including participial clauses and complex sentences, is used flexibly and accurately, with errors rare and non-impeding throughout.
