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 5.5)

The diagram illustrates how the formation of the rain shadow desert takes place involving thousands of kilometers of distance.

Overall, it involves seven stages, beginning with the winds approaching the sea and travelling upwards and ending with the dry winds reaching the inland areas .

First, the winds travel towards the sea coast and as a result are pushed upwards .Subsequently in the third stage as the wind is rising towards the peak of the mountains moisture content rises causing it to cool down. This cooling process taking place in stage 3 results in clouds being formed in stage 4 . As the clouds rise further towards the windward side causing rain to fall.

At the later stages ,starting from stage 6 the dry air resultantly continues over the leeward site of the mountain until the winds reach the inland area on the other side of the mountain eventually resulting in the formation of the rain shadow desert .

Task Achievement / Task Response — Band 5.5

The response provides a clear overview of the process, identifying the main stages from the sea to the inland area. However, the description is somewhat superficial. While you mention the seven stages, you do not fully explain the significance of the 'windward' versus 'leeward' sides in terms of the contrast between precipitation and aridity. The explanation of the cooling process and cloud formation is accurate but lacks the technical precision expected for a Band 7+ response. To improve, ensure you explicitly link the physical changes in the air (moisture loss) to the resulting climate on the leeward side to provide a more comprehensive summary of the 'rain-shadow' phenomenon.

Coherence and Cohesion — Band 5.5

The essay is logically organized, moving chronologically through the stages of the process. You use some cohesive devices such as 'First', 'Subsequently', and 'At the later stages' to guide the reader. However, the paragraphing is slightly unbalanced, with a very short second paragraph. Additionally, some transitions feel a bit mechanical. To reach a higher band, focus on using a wider variety of linking words and ensure that each paragraph has a clear thematic focus, such as separating the 'moist' phase from the 'dry' phase more distinctly.

Lexical Resource — Band 5.5

You have a sufficient range of vocabulary to describe the process, using terms like 'moisture content', 'windward side', and 'leeward site' (note: 'site' should be 'side'). However, there are some minor inaccuracies in word choice, such as 'resultantly' and 'site' instead of 'side'. The vocabulary is generally functional but lacks the sophisticated collocations or precise scientific terminology that would elevate the response to a higher band. Focusing on accurate terminology related to geography and meteorology will help improve your score in this area.

Grammatical Range and Accuracy — Band 5.5

You demonstrate a mix of simple and complex sentence structures. There are several grammatical errors, such as 'the formation of the rain shadow desert takes place involving thousands of kilometers of distance' (which is slightly awkward) and 'As the clouds rise further towards the windward side causing rain to fall' (a sentence fragment). Punctuation is also inconsistent, with unnecessary spaces before periods. While these errors do not impede communication, they occur frequently enough to prevent a higher score. Focus on ensuring every sentence has a clear subject and verb and proofread for minor punctuation slips.
