Image for topic: the diagram below shows the process of greenhouse effect on the earth

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

The image depicts the Sun emitting visible light towards Earth; part of this light is reflected back, while the rest is absorbed by Earth's surface. The absorbed energy is then re-emitted as infrared (IR) radiation, which is partially absorbed and re-radiated by the atmosphere.

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

The diagram illustrate how greenhouse effect on earth works.

Overall, the process involves multiple processes with the sun as the main source of heat and light with infrared radiation as a result.

Greenhoouse effect happens when there is too much heat absorbed by the earth. Sun is the main source of light and heat in our planet and plays a major part with this phenomena. To describe the process, the visible light from the sun is radiated to earth wherein some of it is absorbed by the surface and some bounces back to space as a reflected light. The light absorbed in the planet will be used for its purpose and in return it will be deduced as an infrared light. The infrared light will then decipitate away from the earth but some are re-radiated to the land. The re-radiated light combined with the visible light coming from the sun will result to a hotter weather which will then fall as a greenhouse effect.

Task Response

The report addresses the main stages of the process described in the visual information. However, the response relies heavily on some imprecise terminology (e.g., 'deduced', 'decipitate') and makes some logical leaps regarding the cause of the greenhouse effect that are not explicitly detailed in the diagram. To improve, focus on using more precise scientific verbs (such as 'emitted', 'absorbed', or 'trapped') and ensure the relationship between the different types of radiation is described clearly and accurately according to the visual data.

Coherence & Cohesion

The report follows a logical progression, but the cohesion is weakened by repetitive sentence structures and a lack of sophisticated linking devices. While the sequence of events is understandable, the transitions between the absorption of light and the re-radiation of heat could be smoother. To improve, try using more varied cohesive devices (e.g., 'Subsequently,' 'Following this,' 'As a consequence') to connect the stages of the process more naturally.

Lexical Resource

The vocabulary used is somewhat limited and occasionally inaccurate. For instance, words like 'deduced' and 'decipitate' are used incorrectly in this scientific context; 'emitted' or 'released' would be much more appropriate for radiation. Additionally, there are spelling errors such as 'Greenhoouse.' To reach a higher band, aim to use more precise scientific terminology (e.g., 'absorption,' 'emission,' 'reflection,' 'atmosphere') and ensure that word choices align with the technical nature of the diagram.

Grammatical Range & Accuracy

There are several grammatical issues that affect the overall flow. These include subject-verb agreement errors (e.g., 'The diagram illustrate' instead of 'illustrates') and issues with article usage (e.g., 'the greenhouse effect' instead of 'greenhouse effect'). The sentence structures are mostly simple. To improve, practice using a wider range of complex sentence structures, such as relative clauses (e.g., 'The light that is absorbed by the surface...') and passive voice, which is highly effective for describing processes.
