IELTS Writing Task 1 question
The diagram below shows how geothermal energy is used to produce electricity.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Student answer (Band 5.0)
The given diagram illustrates electricity production process using geothermal energy.
Overall, electricity generation is a multi stage process and includes various phases to generate an electricity. Initiating with cold water and ends with generator which spins using water steam.
To starts with, the stored cold water pumped down to the injection well which is located 4.5km beneath to the ground. After that , this water pass though the geothermal rocks which increase the water temperature and procced to the production well. Further this hot water pumped upwards to the Condenser.
Furthermore, Inside the condenser hot water take from of the steam that passthrough the turbine which spins a generator which later helps to generate an electricity. Lastly this produced electricity transfer for the further use via Electric towers.

Task Achievement / Task Response — Band 5.0
The response fails to meet the minimum word count requirement of 150 words, which significantly impacts the task achievement score. While you have identified the main stages of the geothermal process, the description is quite brief and lacks the necessary detail to fully explain the cycle. For example, you mention the injection well and the condenser, but you do not elaborate on the transformation of energy or the specific role of the geothermal rocks in sufficient detail. To improve, ensure you expand on each stage of the process and provide a more comprehensive overview of the diagram to meet the length requirement and demonstrate a deeper understanding of the information provided.
Coherence and Cohesion — Band 5.5
The essay is organized into logical paragraphs, which helps the reader follow the process. You use some cohesive devices such as 'To start with', 'Furthermore', and 'Lastly' to signal the progression of the stages. However, the flow is occasionally interrupted by awkward phrasing and minor errors in sentence structure. The transition between the injection well and the production well could be smoother. To improve, try to vary your linking words and ensure that each paragraph has a clear topic sentence that guides the reader through the sequence of events.
Lexical Resource — Band 5.0
Your vocabulary is generally adequate for describing a process, using terms like 'geothermal energy', 'injection well', and 'condenser'. However, there are several instances of word-choice errors and awkward phrasing, such as 'take from of the steam' instead of 'takes the form of steam' and 'procced' (a spelling error). The range of vocabulary is somewhat limited, relying on basic verbs like 'pumped' and 'spins'. To reach a higher band, focus on using more precise technical terminology and ensure correct spelling and collocation throughout your writing.
Grammatical Range and Accuracy — Band 5.0
There are frequent grammatical errors throughout the text, including missing articles ('the electricity', 'the generator'), subject-verb agreement issues ('water pass though'), and incorrect preposition usage ('beneath to the ground'). While you attempt to use complex sentences, these are often marred by errors that occasionally impede the flow of information. For example, 'Initiating with cold water and ends with generator' is grammatically incomplete. To improve, focus on basic sentence construction, particularly the correct use of articles and verb tenses when describing a continuous process.
