The diagram below shows how one type of desert, known as a rain-shadow desert, is formed. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram illustrates how a specific type of desert that goes by rain-shadow desert, is formed.
Overall, the development of this phenomenon takes place in two sides of mountains. The wind travels of the sea, over the summit from windward side to leeward side where it has lost its humidity, leaving inland areas dry.
At the beginning of the process, the wind approaches coast where it gets pushed up. The moist air then cools as the temperature is low at high altitudes and by which, clouds are formed. At this point, the wind pushes the clouds even higher. In the freezing temperatures of the summit, the rain finally falls.
At the leeward side, the dry air descending from the summit has travelled thousands of kilometres now. The wind which has lost its humidity, continues forward towards the slope. After reaching the inland areas, the wind leaves behind what is called, rain-shadow desert
What works: You have a clear overview that separates the windward and leeward sides and says the inland area ends up dry. You cover all seven stages in order, and your paragraphs follow the diagram.
Problems:
What works: Your four-paragraph structure (introduction, overview, two bodies) is clear. The windward and leeward split gives each body paragraph a clear focus. You use some sequencing language: At the beginning, then, At this point, After.
Problems:
What works: You use topic-specific words such as windward, leeward, summit, altitudes, descending and inland areas. These suit the task. The vocabulary is adequate and your meaning is mostly clear.
Problems:
I found no spelling mistakes in your answer.
What works: You attempt relative clauses (where it gets pushed up, The wind which has lost…), a participle phrase (leaving inland areas dry) and as-clauses. This shows a mix of simple and complex forms, and most sentences are understandable.
