Image for topic: The diagram below illustrates how a river delta formed. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Our system will evaluate the answer based on this AI-generated description.

The image features a diagram titled "How is a delta formed?" presenting a three-step sequential process labeled with numbered points 1 to 3. Step 1 displays a river flowing between landmasses into a large body of water, accompanied by the text: "1 Velocity slows dramatically when a river meets a large body of water." Step 2 illustrates sediment fragments appearing at the mouth of the river entering the water, labeled: "2 Because of the decrease in velocity, sediments are deposited." Step 3 shows an extensive network of branching sediment channels extending into the water body, labeled: "3 Over time, the sediments build up, forming a delta."

Given the complexity of the image, the above description may not be entirely accurate.

The diagram illustrates the process by which a river delta develops and start collects own form.

Overall, delta formation is a natural process involving three main periods. This process is gradually deposited develops and gathering at the river mouth, when it accumulates and reasons a divide into smaller channels, consequently to turn a delta.

First of all, the river sediments coming from mountain towards the sea. Sediment which is coming from mountain involving sediments like sand,slit and clay, they are going to a river mouth gradually. As well,the sediment deposited towards the sea that can causes toward in accumulates channels.

Meanwhile, transforming in a accumulation channel which happen gradually , it is turning into a smaller channels. That is flows slow down and lost own energy and power, also happen a natural process. As well, smaller channels freezes creating a delta.Consequently, is characterised by a network of distributary channels and small islands.

Task Response

The report attempts to describe the process of delta formation but contains several inaccuracies and unclear expressions. It mentions the key stages (velocity decrease, sediment deposition, and delta formation) but the description is often confusing and includes irrelevant or incorrect details (e.g., 'freezes creating a delta', 'start collects own form'). The overall structure is present, but the language and clarity need improvement. Focus on using precise vocabulary and ensuring each step is logically connected and accurately described.

Coherence & Cohesion

The report attempts to organize the process into stages, but the flow of ideas is often difficult to follow due to unclear referencing and abrupt transitions. The use of cohesive devices is limited and sometimes inaccurate (e.g., 'As well,' 'Consequently,' 'Meanwhile'), which disrupts the logical progression. Paragraphing is not effectively managed, and the overall structure would benefit from clearer topic sentences and smoother linking between stages.

Lexical Resource

The vocabulary range is limited and repetitive, with some inappropriate word choices (e.g., 'start collects own form,' 'reasons a divide,' 'freezes creating a delta'). There is an attempt to use topic-specific terms like 'sediments,' 'deposited,' and 'channels,' but these are not always used accurately. The report would benefit from a wider range of precise vocabulary and more natural collocations to describe the process.

Grammatical Range & Accuracy

The report contains numerous grammatical errors and awkward phrasing that significantly impede understanding. There are issues with subject-verb agreement (e.g., 'the river sediments coming'), missing articles, incorrect verb forms, and incomplete sentences. Punctuation is also problematic, with run-on sentences and missing commas. To improve, the writer should focus on constructing clear, simple sentences and ensuring grammatical accuracy before attempting more complex structures.
