White (crater)

White (crater) 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 White (crater) rather than just read about it. In short: White is a lunar impact crater. It lies on the far side of the Moon from the Earth, to the southwest of the huge walled plain called Apollo.

Key takeaways

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

Reference excerpt

White is a lunar impact crater. It lies on the far side of the Moon from the Earth, to the southwest of the huge walled plain called Apollo. About one crater diameter to the south-southwest is the small crater Hendrix. White is positioned in the central region of the South Pole-Aitken basin. On the lunar geologic timescale, White dates to the Upper Imbrian period. This is a relatively fresh crater with a well-defined rim and interior that have not been significantly worn. There is a small, cup-shaped crater attached to the exterior along the western edge. The inner wall of White displays some slight terracing, and there is a low central ridge near the midpoint of the interior. The spectra of this orthopyroxene-rich peak fits an olivine-bearing gabbroic norite mineralogy, which originated from a depth of 3.9 to 5.8 km. The crater was named in 1970 by the IAU after astronaut Ed White, killed in the Apollo 1 fire. The nearby craters Grissom and Chaffee were named after the other two astronauts killed in the disaster, Gus Grissom and Roger Chaffee.

Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to White.

Worked examples

Example 1 — a first encounter with White (crater)

Start with the simplest possible case. Write down what White (crater) 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 White (crater) 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 White (crater) 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 White (crater)

In research: White (crater) 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 White (crater) 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: White (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ed White (astronaut), Impact craters on the Moon, LQ24 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for White (crater) 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.
