Band 8 sample answer
The provided flow chart illustrates the various environmental consequences resulting from the clear cutting of forests. Overall, it is evident that deforestation initiates a multi-faceted process of ecological damage, which branches into several negative outcomes, including soil degradation, hydrological disruption, and a loss of biodiversity.
One primary consequence of logging is the physical alteration of the land. The use of heavy equipment compresses the soil, causing it to become hard and baked. This prevents water absorption, leading to increased surface runoff and subsequent flooding. Simultaneously, the removal of trees means fewer roots are available to anchor the earth, which results in topsoil erosion. This eroded soil, combined with the destruction of waste wood and the loss of micro-organisms, contributes to the degradation of vegetation.
Furthermore, deforestation disrupts the water cycle. With fewer plants to return moisture to the atmosphere, precipitation levels decrease, which eventually leads to increased drought conditions. Both the degradation of vegetation and the onset of drought facilitate the arrival of pioneer species. Ultimately, these interconnected negative impacts culminate in a significant reduction in overall biodiversity within the affected forest ecosystem.

How to write about process diagrams
- Say how many stages there are and where the process starts and ends.
- Use the passive and sequencers: first, after this, once, finally.
- Keep every stage; a missing step costs task achievement.
- culminate
- to reach a climax or point of highest development
- disruption
- a disturbance or problem that interrupts an event
- interconnected
- having different parts linked or associated with each other
- subsequent
- coming after something in time or order
- multi-faceted
- having many different aspects or features
- facilitate
- to make an action or process easier

Frequently asked questions
What should the overview say?
The flow chart demonstrates that clear cutting forests triggers a complex chain of environmental degradation, ultimately leading to flooding, drought, and a significant reduction in biodiversity.
How long should an IELTS Task 1 answer be?
At least 150 words; 170 to 200 is the safe range. Spend about 20 minutes on it and leave 40 for Task 2, which carries twice the marks.
How do I describe process diagrams?
Say how many stages there are and where the process starts and ends. Use the passive and sequencers: first, after this, once, finally. Keep every stage; a missing step costs task achievement.
