Zemu Glacier

Zemu Glacier is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Zemu Glacier rather than just read about it. In short: Zemu Glacier is the largest glacier in the Eastern Himalaya. It is about 26 kilometres (16 mi) in length and is located at the base of Kangchenjunga in the Himalayan region of Sikkim, India.

Key takeaways

Zemu Glacier belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Zemu Glacier to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Zemu Glacier from memory before moving on to harder problems.

Reference excerpt

Zemu Glacier is the largest glacier in the Eastern Himalaya. It is about 26 kilometres (16 mi) in length and is located at the base of Kangchenjunga in the Himalayan region of Sikkim, India. The Zemu Glacier drains the east side of Kanchenjunga, the world's third highest mountain. The glacier is the source of water for numerous rivers, as it feeds them when it melts. One of them is the Teesta River, which has garnered large attention in the past few years because of a proposed 3500 MW hydropower plant. At the moment the Government of Sikkim has only been able to run a 510 MW plant on the river. Owing to the location of the river in an earthquake prone area, the hydropower plants will be a run of the river project. Zemu Glacier remains a less studied and monitored glacier. Studying digital imagery shows that the glacier has receded 27 meters every year between 1967–1984. The retreat is not massive given the great length of the glacier. There is a thick layer of debris on the glacier, preventing ablation: there are, however, small lakes that have formed on the surface of these debris-covered sections of the glacier.

Changes and Threats Zemu Glacier has seen significant retreat in recent years. The lateral moraine ridges on either side of the glacier are on average 150 feet high. These ridges were created during the Little Ice Age advance. Lateral moraines never get higher than glacier surfaces that create them. This means that the underside of the glacier has thinned by 150 feet in the last century. Another problem on the glacier is the disappearance of its tributaries. Many of its tributaries no longer meet it. This deprives the glacier of a significant portion of its former ice sources. The head of the glacier is fed by debris from the Kanchenjunga slopes. The lower 18 km of the glacier is an ablation zone where melting is immense. Recent studies have shown that between 2000 and 2013 the surrounding glaciers of the Zemu have shrunk drastically, reducing the source for the main glacier and increasing the risk of its shrinkage.

Worked examples

Example 1 — a first encounter with Zemu Glacier

Start with the simplest possible case. Write down what Zemu Glacier claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zemu Glacier before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zemu Glacier ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zemu Glacier

In research: Zemu Glacier appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Zemu Glacier in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Zemu Glacier is common in secondary-school and first-year university syllabi. It links to neighbouring topics Glacier stubs, Glaciers of Sikkim, Glaciers of the Himalayas, so understanding it makes those chapters shorter.
In everyday life: Look for Zemu Glacier outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
