Sha'er Lake coalfield

Sha'er Lake coalfield is a earth 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 Sha'er Lake coalfield rather than just read about it. In short: The Sha'er Lake is a large coal field located in the north of China in Xinjiang. Sha'er Lake represents one of the largest coal reserve in China having estimated reserves of 89.2 billion tonnes of coal.

Key takeaways

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

Reference excerpt

The Sha'er Lake is a large coal field located in the north of China in Xinjiang. Sha'er Lake represents one of the largest coal reserve in China having estimated reserves of 89.2 billion tonnes of coal.

Worked examples

Example 1 — a first encounter with Sha'er Lake coalfield

Start with the simplest possible case. Write down what Sha'er Lake coalfield claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Sha'er Lake coalfield 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 Sha'er Lake coalfield 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 Sha'er Lake coalfield

In research: Sha'er Lake coalfield appears in earth 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 Sha'er Lake coalfield 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: Sha'er Lake coalfield is common in secondary-school and first-year university syllabi. It links to neighbouring topics China geography stubs, Coal in China, Geology of Xinjiang, so understanding it makes those chapters shorter.
In everyday life: Look for Sha'er Lake coalfield 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.
