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 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 reach 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 condensation. 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.

Task Achievement / Task Response — Band 6.0

The response covers the main stages of the rain-shadow desert formation process, identifying the key features such as wind movement, condensation, and the creation of the leeward side. However, the description is somewhat mechanical and lacks a deeper synthesis of the relationship between the stages. While the overview is present, it could be more descriptive of the physical transformation occurring. The mention of 'thousands of kilometers' is a specific detail, but the response would benefit from a more integrated comparison of the windward versus leeward conditions to fully satisfy the requirement for reporting main features and comparisons.

Coherence and Cohesion — Band 6.5

The essay is logically organized into an introduction, overview, and body paragraphs. The progression of ideas is clear, following the chronological order of the diagram. Cohesive devices such as 'In the first stage', 'Following this', and 'In the subsequent stage' are used to guide the reader. However, some transitions feel slightly repetitive or mechanical. Paragraphing is used appropriately to separate the overview from the detailed process. To improve, the student should vary the linking phrases to create a more natural flow between sentences and ideas.

Lexical Resource — Band 6.0

The vocabulary is generally adequate for the task, using subject-specific terms like 'condensation', 'precipitation', 'leeward side', and 'rain-shadow'. There are some minor inaccuracies in word choice, such as 'moist air rises and condensation' (which should be 'undergoes condensation') and 'it cools the vapor' (which is slightly redundant). The range is sufficient to convey the process clearly, but it lacks the sophistication or precision in collocation that would elevate it to a higher band. The vocabulary is functional but remains somewhat basic.

Grammatical Range and Accuracy — Band 6.0

The response uses a mix of simple and complex sentence structures. While the meaning is generally clear, there are several grammatical slips. For example, 'moist air rises and condensation' is grammatically incomplete, and 'dry winds reach inland areas which form the rain-shadow desert' could be punctuated more effectively. There are also minor issues with verb forms and article usage. While these errors do not impede communication, they indicate a need for more consistent control over complex structures to reach a higher band.
