Lade (crater)

Lade (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 Lade (crater) rather than just read about it. In short: Lade is the remains of a lunar impact crater that has been flooded by lava. Its diameter is 58 km.

Key takeaways

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

Reference excerpt

Lade is the remains of a lunar impact crater that has been flooded by lava. Its diameter is 58 km. It was named after German astronomer Heinrich Eduard von Lade. To the north is the crater Godin and to the south-southwest is the worn, lava-flooded Saunder. The southern rim of Lade has been completely covered or destroyed, and there are gaps in the relatively thin southeast rim. The surviving crater wall is worn and somewhat hexagonal in outline. There is a smaller bowl-shaped crater attached to the interior of the western rim. To the north the crater designated Lade B has been completely filled with lava.

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 Lade.

Worked examples

Example 1 — a first encounter with Lade (crater)

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

In research
Lade (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 Lade (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
Lade (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ20 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Lade (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.
