IELTS Academic Task 1: How to Describe a Process Diagram

Describe the stages in order using the passive voice and sequencing language; no numbers needed.

Structure

1. Introduction — paraphrase what the visual shows.
2. Overview — the 2–3 biggest features or trends (essential for Band 7+).
3. Detail paragraph 1 — describe and compare the main data with figures.
4. Detail paragraph 2 — cover the rest.

Useful language

• first / next / after that / finally
• is then transported to
• once this is complete
• the … is carried out

Watch real processes, then describe them

Process-diagram tasks reward clear sequencing language: first, next, after this, finally. Each simulation below runs a natural or scientific process step by step, which makes good practice material for describing stages in your own words.
