Parry (crater)

Parry (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 Parry (crater) rather than just read about it. In short: Parry is a lunar impact crater that is attached to the southeast rim of the walled plain named Fra Mauro. Attached to the west and southwest rim of Parry is the crater Bonpland.

Key takeaways

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

Reference excerpt

Parry is a lunar impact crater that is attached to the southeast rim of the walled plain named Fra Mauro. Attached to the west and southwest rim of Parry is the crater Bonpland. Due south of Parry is the small crater Tolansky, and farther to the south-southwest is Guericke. The rim of Parry is heavily worn and slightly distorted due to the co-joined formations. The wall is the most prominent along the northwest, and crossed along the southwest by the small Parry B. The floor has been flooded by lava, and is relatively flat. At the midpoint is a pair of small craters. This crater was named after British explorer William Parry (1790–1855). The designation was formally adopted into lunar nomenclature by the International Astronomical Union in 1935. A rille system, called the Rimae Parry, crosses the region in a series of graben. One rille crosses the southeast rim of Parry in a northeast direction before crossing the east rim and continuing a short distance across the surrounding mare. Another extends from Tolansky crater across the west side of Parry and into Fra Mauro crater. One other crosses the north rim of Bonpland crater and into Fra Mauro where it intersects with another rille.

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 Parry.

The following craters have been renamed by the IAU.

Parry A — See Tolansky (crater).

Worked examples

Example 1 — a first encounter with Parry (crater)

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

In research: Parry (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 Parry (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: Parry (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ19 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Parry (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.
