Warner (crater)

Warner (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 Warner (crater) rather than just read about it. In short: Warner is a lunar impact crater that is located in the southern part of the Mare Smythii, near the eastern limb of the Moon. In this location the crater is viewed almost from the edge from Earth, and is sometimes hidden from sight due to libration.

Key takeaways

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

Reference excerpt

Warner is a lunar impact crater that is located in the southern part of the Mare Smythii, near the eastern limb of the Moon. In this location the crater is viewed almost from the edge from Earth, and is sometimes hidden from sight due to libration. The crater lies just to the south-southeast of the very similar Runge. To the southwest is Widmannstätten, and to the south is the merged Kao–Helmert crater pair. This crater has been almost completely submerged by lava flows, leaving only a shallow outer rim projecting up through the surface. The surviving rim is nearly circular, and has low sections along the northern and southern faces. The interior floor is similar in appearance to the surrounding lunar mare, and is marked only by a few tiny craterlets. There is a small, shallow crater just to the southwest of the outer rim. The depth of the crater is about 510 meters, from the lowest parts of the crater floor to the highest portion of the northwestern rim.

The crater in named after Worcester Reed Warner; the name was approved by the IAU in 1976.

Worked examples

Example 1 — a first encounter with Warner (crater)

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

In research: Warner (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 Warner (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: Warner (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ21 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Warner (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.
