Trident (crater)

Trident (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 Trident (crater) rather than just read about it. In short: Trident is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed about 300 m north of its rim in 1972, on the Apollo 17 mission.

Key takeaways

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

Reference excerpt

Trident is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed about 300 m north of its rim in 1972, on the Apollo 17 mission. They drove along the east rim of Trident during EVA 1 of the mission, in their rover. To the south of Trident is Powell, to the west are Camelot and Horatio, and to the east is Sherlock. The crater was named by the astronauts after a trident (three pronged spear) due to its shape.

Worked examples

Example 1 — a first encounter with Trident (crater)

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

In research
Trident (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 Trident (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
Trident (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Apollo 17, Impact craters on the Moon, LQ12 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Trident (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.
