Lacus Temporis

Lacus Temporis 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 Lacus Temporis rather than just read about it. In short: Lacus Temporis (Latin temporis, Lake of Time) is a small lunar mare that is located in the northeastern quadrant of the Moon's near side. The selenographic coordinates of this feature are 46.77°N 56.21°E / 46.77; 56.21, and it lies within a diameter of 205 km.

Key takeaways

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

Reference excerpt

Lacus Temporis (Latin temporis, Lake of Time) is a small lunar mare that is located in the northeastern quadrant of the Moon's near side. The selenographic coordinates of this feature are 46.77°N 56.21°E / 46.77; 56.21, and it lies within a diameter of 205 km. It was named by the IAU in 1976. This small mare is composed of two large, roughly circular patches of relatively smooth surface, with a pair of small, cup-shaped craters located prominently at their intersection. Both of these regions of basaltic lava covered surface have some smaller side lobes, which are most likely impact features that have become flooded. Just to the southwest of this feature is the crater Chevallier and to the southeast lies Carrington.

Worked examples

Example 1 — a first encounter with Lacus Temporis

Start with the simplest possible case. Write down what Lacus Temporis 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 Lacus Temporis 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 Lacus Temporis 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 Lacus Temporis

In research: Lacus Temporis 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 Lacus Temporis 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: Lacus Temporis is common in secondary-school and first-year university syllabi. It links to neighbouring topics LQ05 quadrangle, Maria on the Moon, so understanding it makes those chapters shorter.
In everyday life: Look for Lacus Temporis 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.
