Examiners love the “worms and derelict sites” topic for several reasons:

Derelict sites—such as abandoned factories, former quarries, and disused landfills—present a severe environmental challenge. Centuries of industrialization have left behind vast tracts of land that are completely hostile to plant life. These sites typically suffer from:

To maximise your learning, treat this passage as a diagnostic test. Read the passage once for general understanding (no more than 3–4 minutes). Then answer the 13 questions without looking at the answer key. Once complete, review your responses against the answer key and explanations provided above. For every incorrect answer, trace back to the passage line indicated and ask yourself: “Why did I miss this?” Common errors include misreading the question requirements (especially the “NO MORE THAN TWO WORDS” instruction), failing to notice paraphrasing, and spending too much time on a single question. By addressing these patterns, you will build the speed and accuracy needed for a high IELTS Reading band score.

The internal environment of an earthworm is a highly active bioreactor. The mucus and fluids inside the worm's gut stimulate dormant soil microbes. When earthworms excrete casts, they deposit concentrated populations of beneficial bacteria and fungi back into the soil. This microbial spike accelerates the natural decomposition of organic matter, establishing a self-sustaining nutrient cycle.

6. In research at Bell College, worms were used that quickened: soil recomposition 8. The soil at Hallside will be enriched by adding air and: 9. Contaminants will be removed from the soil by: (specifically their root systems). Course Hero Brief Explanation of Key Facts Species Used : About 21,000 " garden lobworms black-headed worms " were released . Without them, natural recovery could take up to The Process

The digestive process breaks down complex organic matter, converting locked nutrients into accessible forms of nitrogen, exchangeable calcium, and soluble phosphorus. 3. Boosting Microbial Activity

Worms dig deep vertical tunnels. This breaks up compacted, industrial soil.

: Focus on identifying keywords like species names or specific chemical contaminants. Study Guide Strategy Focus on Paraphrasing Project Goal What is unique about the earthworms

The text describes a pioneering, low-cost project to reclaim 30 hectares of contaminated land. Because the site was poisoned with heavy metals like chromium, lead, and cadmium, traditional building was impossible. The solution involved covering the land with a layer of sewage and colliery waste, then introducing thousands of deep-burrowing earthworms (specifically Lumbricus terrestris Aporrectodea longa ) to accelerate soil regeneration. Studocu Vietnam Key Reading Answers & Explanations

Naturally, this soil restoration could take up to 60 years . However, with the aid of these deep-burrowing worms, the timeline is reduced to just 5 to 10 years . 3. Biological Mechanisms of Restoration

⚠️

Accelerates the chemical breakdown of toxic industrial residues into harmless compounds.

While the benefits of earthworms are clear, introducing them to a derelict site is not as simple as dropping them onto the dirt. A highly toxic or completely barren site can quickly kill introduced populations. Successful restoration requires a strategic, phased approach. The Role of Pioneer Plants
