Ross (lunar crater)

Ross (lunar 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 Ross (lunar crater) rather than just read about it. In short: Ross is a lunar impact crater that is located in the northwest part of the Mare Tranquillitatis. It lies south-southwest of the crater Plinius, and northeast of the lava-flooded Maclear.

Key takeaways

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

Reference excerpt

Ross is a lunar impact crater that is located in the northwest part of the Mare Tranquillitatis. It lies south-southwest of the crater Plinius, and northeast of the lava-flooded Maclear. The crater has a diameter of 24.5 km and a depth of 2.36 km. This impact dates to the Eratosthenian period of the lunar geologic timescale. The crater has a generally circular shape, but is not quite symmetrical. The inner walls slope down to a base of slumped material, before joining a relatively level interior floor. There is a low ridge to the west of the crater midpoint.

This crater was named by the IAU in 1935, after British explorer James Clark Ross (1800-1862) and American astronomer and optician Frank E. Ross (1874-1966). Its designation was formally adopted by the International Astronomical Union in 1935.

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 Ross.

Worked examples

Example 1 — a first encounter with Ross (lunar crater)

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

In research: Ross (lunar 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 Ross (lunar 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: Ross (lunar crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ12 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Ross (lunar 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.
