Guilbert (crater)

Guilbert (crater) is a earth 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 Guilbert (crater) rather than just read about it. In short: Guilbert is a small (25.5 km diameter) impact crater on the surface of Venus. It has a continuous ejecta radius of 16.3 km, and a wall width of 2.5 km.

Key takeaways

Guilbert (crater) belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Guilbert (crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Guilbert (crater) from memory before moving on to harder problems.

Reference excerpt

Guilbert is a small (25.5 km diameter) impact crater on the surface of Venus. It has a continuous ejecta radius of 16.3 km, and a wall width of 2.5 km. Its name derives after Yvette Guilbert. It was accepted by the IAU in the year 1991.

Surrounding geology

The physical environment immediately surrounding the crater includes:

Lhamo Tessera, a remnant of an ancient tessera plateau (a complex ridged terrain experiencing intense multi-directional deformation). Eithinoha Corona, a large (400 km in diameter) circular structure categorized as a corona (a near-circular volcanotectonic feature). Hsueh T'ao Crater, a young, mid-size impact crater to the north.

Worked examples

Example 1 — a first encounter with Guilbert (crater)

Start with the simplest possible case. Write down what Guilbert (crater) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Guilbert (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 Guilbert (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 Guilbert (crater)

In research: Guilbert (crater) appears in earth 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 Guilbert (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: Guilbert (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astrogeology stubs, Impact craters on Venus, Venus stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Guilbert (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.
