Loch A'an

Loch A'an 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 Loch A'an rather than just read about it. In short: Loch A'an is a remote freshwater loch set deep within the central Cairngorms plateau, in the Cairngorms National Park, located in the eastern Highlands of Scotland. Loch A'an, also called Loch Avon, is the source of the River Avon.

Key takeaways

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

Reference excerpt

Loch A'an is a remote freshwater loch set deep within the central Cairngorms plateau, in the Cairngorms National Park, located in the eastern Highlands of Scotland. Loch A'an, also called Loch Avon, is the source of the River Avon. Loch A'an is oriented southwest–northeast and is bounded on three sides by precipitous mountains, cliffs and crags, with the North-East opening out to provide an outflow for the river through Glen Avon.

Geography

To the north of the loch, rising almost vertically, lies the Cairn Gorm, the sixth highest mountain in the United Kingdom. Southwest of Cairn Gorm, at the head of the loch, lies the imposing peak of Ben Macdui, the second-highest mountain in the UK, and to east lies Beinn Mheadhoin, the thirteenth-highest mountain in the UK, again rising almost vertically from the Loch A'an basin. Lying 1.2 kilometres (3⁄4 mile) south of the loch and 202 m (663 ft) higher up the range at an elevation of 927 m (3,041 ft), lies Loch Etchachan.

Poem Nan Shepherd wrote a short poem about the loch in her 1934 anthology In the Cairngorms.

Worked examples

Example 1 — a first encounter with Loch A'an

Start with the simplest possible case. Write down what Loch A'an 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 Loch A'an 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 Loch A'an 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 Loch A'an

In research
Loch A'an 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 Loch A'an 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
Loch A'an is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cairngorms, Freshwater lochs of Scotland, Highland (council area) geography stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Loch A'an 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.
