Loch Anna

Loch Anna 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 Anna rather than just read about it. In short: Loch Anna is a small, upland, freshwater loch approximately 2.4 km (1.5 mi) north of Loch Alsh at Ardelve, in Lochalsh, Scotland. It lies in a northwest to southeast direction, is approximately 0.5 km (0.31 mi) in length, and is at an altitude of 317 m (1,040 ft).

Key takeaways

  • Loch Anna 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 Anna to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Loch Anna from memory before moving on to harder problems.

Reference excerpt

Loch Anna is a small, upland, freshwater loch approximately 2.4 km (1.5 mi) north of Loch Alsh at Ardelve, in Lochalsh, Scotland. It lies in a northwest to southeast direction, is approximately 0.5 km (0.31 mi) in length, and is at an altitude of 317 m (1,040 ft). The loch is irregular in shape, is on average 4 m (13 ft) deep, with a maximum depth of 8.2 m (27 ft). It was surveyed in 1904 by James Murray as part of Sir John Murray's Bathymetrical Survey of Fresh-Water Lochs of Scotland 1897-1909.

Worked examples

Example 1 — a first encounter with Loch Anna

Start with the simplest possible case. Write down what Loch Anna 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 Anna 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 Anna 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 Anna

In research
Loch Anna 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 Anna 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 Anna is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater lochs of Scotland, Highlands, so understanding it makes those chapters shorter.
In everyday life
Look for Loch Anna 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.
