Grand Chasms

Grand Chasms 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 Grand Chasms rather than just read about it. In short: The Grand Chasms (78°35′S 39°30′W) are two or more deep crevasses in the Filchner Ice Shelf, Antarctica, extending west for an unknown distance from 37°W, close west of the Touchdown Hills. The feature is the most notable crevassed area on the Filchner Ice Shelf, roughly 60 miles (100 km) long and from 0.25 to 3 miles (0.4 to 4.8 km) wide.

Key takeaways

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

Reference excerpt

The Grand Chasms (78°35′S 39°30′W) are two or more deep crevasses in the Filchner Ice Shelf, Antarctica, extending west for an unknown distance from 37°W, close west of the Touchdown Hills. The feature is the most notable crevassed area on the Filchner Ice Shelf, roughly 60 miles (100 km) long and from 0.25 to 3 miles (0.4 to 4.8 km) wide. It was discovered by the Commonwealth Trans-Antarctic Expedition, 1955–58. During 1957 it was examined by a U.S. party from Ellsworth Station led by Edward Thiel, who applied the descriptive name.

Worked examples

Example 1 — a first encounter with Grand Chasms

Start with the simplest possible case. Write down what Grand Chasms 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 Grand Chasms 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 Grand Chasms 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 Grand Chasms

In research: Grand Chasms 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 Grand Chasms 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: Grand Chasms is common in secondary-school and first-year university syllabi. It links to neighbouring topics Antarctica geography stubs, Bodies of ice of Queen Elizabeth Land, Crevasse fields of Antarctica, so understanding it makes those chapters shorter.
In everyday life: Look for Grand Chasms 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.
