Yamato 791197

Yamato 791197 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 Yamato 791197 rather than just read about it. In short: Yamato 791197, official abbreviation Y-791197, is a meteorite that was found in Antarctica on November 20, 1979. It is the first lunar meteorite to be found on Earth, but was not identified as such until 1984, after the lunar origin of ALH 81005 was recognised.

Key takeaways

  • Yamato 791197 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Yamato 791197 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Yamato 791197 from memory before moving on to harder problems.

Reference excerpt

Yamato 791197, official abbreviation Y-791197, is a meteorite that was found in Antarctica on November 20, 1979. It is the first lunar meteorite to be found on Earth, but was not identified as such until 1984, after the lunar origin of ALH 81005 was recognised. It was collected by the National Institute of Polar Research, Japan.

Classification and characteristics Weighing 52.4 grams, it is a weakly shocked feldspathic regolith breccia believed to have come from the lunar highlands on the far side of the Moon. It is classified as lunar-anorthositic breccia, a lunar meteorite that is primarily anorthositic.

Worked examples

Example 1 — a first encounter with Yamato 791197

Start with the simplest possible case. Write down what Yamato 791197 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 Yamato 791197 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 Yamato 791197 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 Yamato 791197

In research
Yamato 791197 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 Yamato 791197 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
Yamato 791197 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Achondrite meteorites, Lunar meteorites, Meteorites found in Antarctica, so understanding it makes those chapters shorter.
In everyday life
Look for Yamato 791197 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.
