The blog first presents a specific sample question on IELTS Academic Writing Task 1 based on Line Graphs. It is then followed by three model answers to the same specific question on Line Graphs which can be easily compared by the students to score a higher band score in the IELTS exam.

There will be a picture or diagram in IELTS Writing Task 1 of the academic version on which you must compose a report. The line graphs could be one of several graphic representations. An example of a line graph for IELTS Writing Task 1 that discusses the causes of air pollution in the UK over time is provided below. Let's use the ideas we have to determine how to structure the report.

IELTS Writing Task 1 – Line Graph Sample Answer 1

The line graph presents information on three causes of air pollution in the UK from 1990 to 2005.

It is evident that the total number of air pollutants has reduced over time. Industrial-related air pollution has largely decreased significantly.

Nearly 7 million tonnes of air pollutants were present in the UK overall in 1990. In 1999, this amount fell precipitously to 4 million tonnes. Following that, it continued to decline, reaching a little over 3 million tonnes at the end of the aforementioned period.

The industry emitted 5.5 million tonnes of air pollutants in 1990. This amount then decreased over the course of time, reaching 2 million tonnes by 2005, with a particularly rapid reduction occurring between 1993 and 1996. In contrast, the amount of air pollution from home and transportation sources was smaller.

From 1990 to 2005, the amount of air pollution caused by transportation remained essentially unchanged at 1 million tonnes. On the other hand, residential pollution dropped from about 1 million tonnes in 2005 to just under 0.1 million tonnes.

Significant air pollution sources in the UK between 1990 and 2005 are depicted in the graph.

The level of air pollution has mostly decreased throughout time, with the transportation sector being the lone exception, where it has increased.

With over 6 million tonnes, the industrial sector led all other sources of air pollution in the UK in 1990. The total was roughly 8 million tonnes when added to other sectors. Every family and the transportation industry produced 1 million tonnes annually.

The overall amount of pollutants released into the air during the following fifteen years steadily fell to 5 million tonnes, a decrease of roughly 2 million tonnes. Additionally, this was accomplished since the industrial sector likewise has shown a yearly decrease in emission rate.

This was just 2 million tonnes in 2005, a decline of around 4 million tonnes overall. When the household sector and the transportation sector are taken into account, there is a difference in the rate of air pollution.

From 1990 to 1999, the UK's household emittance rate stayed constant at 1 million tonnes. However, it dramatically decreased after 1999, reaching absolute zero in 2005. On the other hand, the amount of pollution by the transport industry has grown rapidly since 1999, reaching 3 million tonnes in 2005.

IELTS Writing Task 1 – Line Graph Sample Answer 3

The given graph shows the four UK industries and the amount of air pollutants they each released between 1990 and 2005. The four distinct colored lines indicate the overall amount of industrial, transport, and residential sectors. The measurements are presented in million tonnes.

If the whole picture is taken into account, we may observe a decrease in the weight of air pollutants between 1990 and 2005.

The graph above shows that in 1990, the industrial sector had the greatest impact on air pollution. It survives by releasing up to 6 million tonnes of atmospheric pollution. In the UK, homes and the transportation sector were both at the same threshold of only 1 million tonnes at the same time. It stayed at 1 million tonnes together with the home sector until 1999, with a minor blip in the transportation sector.

The overall amount of air pollutants released decreased significantly during the following fifteen years, and it continued to drop until it reached 5 million tonnes annually in 2005. Consequently, there was a 2 million tonnes difference in the amount of air pollutants released.

With a decrease of 2 million tonnes from 1990, when there were roughly 6 million tonnes, to 2005, the industry underwent a substantial transition in terms of the sector.

Additionally, after remaining consistent for a sizable portion of the fifteen years under consideration, families in the UK attained the zero-emission goal in 2005. In 1999, the decline got underway.

On the other hand, the number of air pollutants discharged into the atmosphere by the transportation sector increased rapidly in 1999. It was 4 million tonnes in 2005.
