Krieger (crater)

Krieger (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 Krieger (crater) rather than just read about it. In short: Krieger is a lunar impact crater on the eastern part of the Oceanus Procellarum. It is located to the north-northwest of the flooded crater Prinz, and north-northeast of the prominent ray crater Aristarchus.

Key takeaways

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

Reference excerpt

Krieger is a lunar impact crater on the eastern part of the Oceanus Procellarum. It is located to the north-northwest of the flooded crater Prinz, and north-northeast of the prominent ray crater Aristarchus. To the northwest lies the small Wollaston. The crater was formally named in 1935. In the past the floor of Krieger has been flooded by basaltic lava, leaving only a low, circular, somewhat polygonal ridge formed by the rim. The southern rim is broken across by the small Van Biesbroeck, and there is a small gap in the western rim. A meandering rille leads away from this break toward the northwest. Krieger is a crater of Upper (Late) Imbrian age.

Nearby craters Two tiny craters next to the eastern rim have been designated Rocco and Ruth. Rocco was previously designated as Krieger D before being named by the IAU.

The nearby surface to the southwest contains a number of rilles belonging to the Rimae Aristarchus and Rimae Prinz rille systems. Further to the east-southeast are the Montes Harbinger mountains.

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 Krieger.

The following craters have been renamed by the IAU.

Krieger B — See Van Biesbroeck (crater).

Worked examples

Example 1 — a first encounter with Krieger (crater)

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

In research: Krieger (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 Krieger (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: Krieger (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ10 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Krieger (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.
