Lowell (Martian crater)

Lowell (Martian 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 Lowell (Martian crater) rather than just read about it. In short: The Lowell crater is a large impact crater on Aonia Terra in the Thaumasia quadrangle of Mars. The crater is about 203 kilometers (127 miles) in diameter.

Key takeaways

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

Reference excerpt

The Lowell crater is a large impact crater on Aonia Terra in the Thaumasia quadrangle of Mars. The crater is about 203 kilometers (127 miles) in diameter. Lowell is an example of a well-preserved peak ring crater on Mars. Lowell's ejecta blanket and associated secondary craters are dissected by channels. Nearby features include the craters Slipher to the north, Douglass to the east, and Coblentz to the southwest, the small mountain Aonia Mons to the west, and Aonia Planum to the southeast. Lowell crater is named for Percival Lowell who built the Lowell Observatory in Flagstaff, Arizona, in 1894, and then started observing Mars intensively for years. He used the observatory and his large refractor telescope to discover what he believed were over 500 canals on Mars. Lowell promoted the idea that they were constructed by an intelligent race of Martians. However, when pictures were received from spacecraft, the canals were found to be optical illusions. Nevertheless, much of the later interest in Mars exploration resulted from the efforts of Lowell.

Worked examples

Example 1 — a first encounter with Lowell (Martian crater)

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

In research: Lowell (Martian 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 Lowell (Martian 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: Lowell (Martian crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on Mars, Mars crater stubs, Thaumasia quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Lowell (Martian 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.
