IELTS Writing Task 1 question

The diagram below shows how one type of desert, known as a rain-shadow desert, is formed.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The formation of rain-shadow deserts

Student answer (Band 6.0)

The diagram illustrates the stages involved in the natural process of the formation of a rain-shadow desert.

Overall, the process consists of seven main stages, starting with the winds approaching the coast from the sea. The process terminates with the dry winds reaching inland areas which form the rain-shadow desert.

In the first stage of the process, winds approach the coast from the sea. Following this, they move in an upward direction. As a result of this, moist air rises and condenses. Following this, it cools the vapor and forms clouds. Clouds undergo a transformation and release precipitation onto the mountain over a period of time.

In the subsequent stage of the process, the leeward side forms as dry air continues onto the mountain. Finally, dry winds reach the inland areas and they form a rain-shadow desert. Additionally, the distance from the coast to inland is estimated to be thousands of kilometers.

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

The response provides a clear overview of the rain-shadow desert formation process. It identifies the main stages, from the initial wind movement to the final formation of the desert. However, the description of the process is somewhat mechanical and lacks detail regarding the specific geographical features shown in the diagram, such as the windward versus leeward slopes or the specific altitude changes. While the main features are reported, the analysis could be more insightful by linking the stages more effectively to the visual data provided. The inclusion of the 'thousands of kilometers' detail is a good attempt at incorporating data, but overall, the development of the process description remains somewhat superficial.

Coherence and Cohesion — Band 6.5

The response is logically organized, with a clear introduction, overview, and body paragraphs that follow the chronological order of the process. Cohesive devices such as 'In the first stage', 'Following this', and 'In the subsequent stage' are used to guide the reader through the sequence. However, the use of these devices is slightly repetitive and mechanical at times. Paragraphing is used appropriately to separate the overview from the detailed process description. The progression of ideas is clear, but the flow could be improved by using a wider variety of linking phrases to connect the stages more naturally.

Lexical Resource — Band 6.0

The vocabulary is adequate for the task, with terms like 'condenses', 'precipitation', 'leeward', and 'transformation' used correctly. However, the range is somewhat limited, and there is a reliance on simple verbs and repetitive phrasing (e.g., 'process' is used frequently). To reach a higher band, the student should incorporate more precise academic vocabulary to describe the meteorological and geographical changes, such as 'moisture-laden winds', 'orographic lift', or 'arid conditions'. The current lexical range is sufficient to convey the meaning clearly, but it lacks the sophistication and flexibility required for higher bands.

Grammatical Range and Accuracy — Band 6.0

The response demonstrates a mix of simple and complex sentence structures. Most sentences are grammatically accurate, and errors are rare and do not impede communication. For instance, 'As a result of this, moist air rises and condenses' is a well-constructed complex sentence. However, the range of structures is somewhat limited; there is a lack of more advanced grammatical features such as passive voice constructions, which are often useful when describing scientific processes. The punctuation is generally correct, and the overall control of grammar is solid, though it does not show the full flexibility required for a higher band.
