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 6.0)

the given diagram is in fact the simplest blue print of the geothermal energy production process in which the geothermal feature of Earth is used to heat up the cold water, turns it into steam which is then condensed to run turbines which produced electricity as the product.

this process starts on the surface of groung where the cold water, with the help of heavy duty pumps, is pumped down stream till the geothermal zone of our globe which is 4.5km in depth, through an inlet. the tempreture down there is more than the boiling point so the water beacomes extremly hot and ready to turns into steam.

After this, there is an outlet from where this boiling water pumped up and turns into steam. on the top of this outlet there is a condensor which simply condense all the steam and puff it towards the turbine through a narrow passage, as this steam hits the fans of turbine it begin to rotate and generator which powered with this turbine starts and begin to produce electricity.

this electricity from these big generators then transmited to trimission tower and it reaches our homes through transmission lines.

Task Achievement / Task Response: Band 6.5

You cover the main sequence from pumping cold water underground to generating electricity, and you include the key depth of 4.5 km. The opening also attempts an overview of how heat from the geothermal zone drives the process. However, some details are misreported: the water is heated underground and pumped back up as hot water; the condenser then produces steam, rather than condensing steam and sending it onward. The final claim that electricity reaches homes is not shown in the diagram, which only depicts transmission lines and a pylon. Your account is relevant and covers the stages, but clearer, more precise descriptions of the conversion points and a concise overview would make it more complete.

Coherence and Cohesion: Band 6.5

The response follows the process in a generally logical order, moving from the underground wells to the surface equipment and then electricity transmission. Paragraphing also separates the initial overview from the detailed sequence. Linking phrases such as “this process starts,” “After this,” and “from where” help show progression, although some connections are awkward or unclear. For example, “After this” does not clearly distinguish the production well from the condenser, and the final sentence adds an outcome beyond the diagram. To strengthen the organisation, give each paragraph a clear function and use precise references to each stage, so the reader can follow the flow without having to infer what “this” or “it” refers to.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “geothermal zone,” “inlet,” “outlet,” “turbine,” and “generator,” and make some attempts at more descriptive language. However, several choices are inaccurate or informal for a technical report. “Puff it towards the turbine” is not an appropriate description of steam flow, while “fans of turbine” and “trimission tower” are unclear. There are also noticeable spelling errors, including “groung,” “tempreture,” “beacomes,” and “condensor,” which reduce precision. Aim for standard technical collocations and check spelling carefully; accurate terms such as “steam is directed through a pipe” will communicate the process more clearly than vivid but imprecise wording.

Grammatical Range and Accuracy: Band 5.0

You attempt both longer sentences and sequencing clauses, but control is uneven, and errors sometimes make the process difficult to follow. For example, “the water beacomes extremly hot and ready to turns into steam” has problems with verb form and sentence construction; “this boiling water pumped up” is missing an auxiliary verb; and “generator which powered with this turbine starts” has errors in the relative clause and verb form. Capitalisation after full stops is also inconsistent. Practise forming complete passive clauses for process descriptions, such as “The water is pumped up” and “It is then converted into steam.” Shorter, accurately punctuated sentences would help you retain some complexity without losing grammatical control.
