The formation of rain-shadow deserts

What works: You wrote an overview, and you correctly noticed that the diagram splits into a windward side with five stages and a leeward side with two. Your introduction paraphrases the title rather than copying it. You also picked up the "thousands of kilometres" scale.

Problems:

1. The overview describes the structure of the diagram but not the main idea. It never says that the moist air loses its rain on the windward side, so the air reaching the other side is dry and creates a desert.
   • ❌ "On the sea-side, there are 5 stages from ocean winds blowing toward the coast to rainfall releasing from the clouds. In contrast, on the other side of the mountain, 2 stages make rain-shadow desert creation happen."
   • ✅ "On the windward side, moist air is forced upwards and loses its moisture as rain, whereas on the leeward side the remaining air is dry, so a desert develops inland."

1. You added information that is not in the diagram. Nothing in it mentions "no cool weather" or says that the environment is "completely dry". "Thousands of kilometres" is the distance from the coast to the inland area. It is not a stretch of dry land across the mountains.
   • ❌ "Over thousands of kilometres across the mountains, there is no cool weather. The environment is completely dry so the dry air progresses over the mountain downward."
   • ✅ "Having lost its moisture, the dry air continues over the mountain (stage 6) and moves down the leeward side."

1. You misread the first stages. The winds approach the coast from the sea, and they are pushed upwards, presumably by the rising land. They do not approach "the sea".
   • ❌ "winds which are approaching the sea move upward toward the mountain"
   • ✅ "winds from the sea approach the coast and are then pushed upwards by the mountains."

1. The body compresses stages 1–4 into one sentence and a half, and the stage order is not clear. Stage 3 (moist air rises and cools) and stage 4 (clouds form) are blended together, and stage 5 is described vaguely.
   • ❌ "Near the top of the mountain, because of clouds, rain starts to fall."
   • ✅ "This cooling causes clouds to form, and rain finally falls on the windward side of the mountains."

What works: You have four clear paragraphs (introduction, overview and two bodies), and the order of ideas follows the diagram. "In contrast" and "Once" are used sensibly.

Problems:

1. Sequencing language is thin. "In the first stage" is the only ordering phrase, and nothing follows it (no "then", "subsequently", "finally"). For a process, the reader should be able to follow each step.
   • ❌ "In the first stage, winds which are approaching the sea move upward..."
   • ✅ "The process begins when winds from the sea approach the coast. These winds are then pushed upwards..."

1. The link between ideas is unclear or illogical in places. "so" in the final paragraph suggests the dryness causes the air to move over the mountain, which is not the relationship in the diagram.
   • ❌ "The environment is completely dry so the dry air progresses over the mountain downward."
   • ✅ "Having lost its moisture, the dry air continues over the mountain and moves down the leeward side."

1. The overview is mechanical. It counts stages ("5 stages", "2 stages") instead of linking the two sides by cause and effect, so the reader does not see why a desert forms.
   • ❌ "In contrast, on the other side of the mountain, 2 stages..."
   • ✅ "Whereas on the leeward side, the remaining air is dry, so a desert develops inland."

What works: Your vocabulary is adequate for the task and the meaning is always clear. You use topic words such as "windward", "leeward", "moist air" and "inland", and you avoid copying the diagram labels word for word.

Problems:

1. Some word choices are unnatural or imprecise.
   • ❌ "rainfall releasing from the clouds"
   • ✅ "rain falling from the clouds"

1. "Make … creation happen" is awkward, and the noun phrase is hard to read.
   • ❌ "2 stages make rain-shadow desert creation happen"
   • ✅ "…which results in the formation of a rain-shadow desert."

1. Other imprecise phrases:
   • ❌ "the sea-side" → ✅ "the windward side"
   • ❌ "inland sites" → ✅ "inland areas"
   • ❌ "progresses over the mountain downward" → ✅ "descends the leeward side"

There are no real spelling errors in this answer, so no spelling table is needed.

What works: You mix simple and complex sentences, including a relative clause ("winds which are approaching"), a because of phrase, an as clause and a once clause. Most sentences can be understood.

Problems:

1. Missing articles (repeated):
   • ❌ "a kind of desert called rain-shadow desert" → ✅ "a kind of desert called a rain-shadow desert"
   • ❌ "2 stages make rain-shadow desert creation happen" → ✅ "two stages lead to the formation of a rain-shadow desert"
   • ❌ "the formation process of a kind of desert" → ✅ "the process by which a rain-shadow desert is formed"

1. Punctuation and spacing:
   • ❌ "toward the mountain.As this moist air rises"
   • ✅ "toward the mountain. As this moist air rises"

1. Present continuous used where simple present or passive fits better in a process description:
   • ❌ "winds which are approaching the sea move upward"
   • ✅ "winds approach the coast and are pushed upwards"

1. Numerals under ten should be written as words, and "5 stages" would read better as "five stages". This is a minor style point.

1. You use almost no passive forms ("are pushed", "is formed", "is released"), which are normal in process descriptions. Adding them would extend your range.

1. Make the overview explain the process. State that the windward side loses its moisture as rain, so the air reaching the leeward side is dry and creates a desert. Do not just count the stages.
2. Report only what the diagram shows. Remove "no cool weather" and "completely dry", and check each stage label (1–7) against your sentences.
3. Add sequencing language and passives. Use first, then, subsequently, finally and forms like are pushed, is formed, and fix the missing articles and the spacing after "mountain."
