Greenland Plain

Greenland Plain 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 Greenland Plain rather than just read about it. In short: The Greenland Abyssal Plain at 75°N 3°W is a bathymetric depression in the Greenland Sea. It is delimited by Mohns Ridge and Jan Mayen pressure zone in the South and separated by a smaller ridge to the Boreas Abyssal Plain in the North.

Key takeaways

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

Reference excerpt

The Greenland Abyssal Plain at 75°N 3°W is a bathymetric depression in the Greenland Sea. It is delimited by Mohns Ridge and Jan Mayen pressure zone in the South and separated by a smaller ridge to the Boreas Abyssal Plain in the North.

Oceanography In 1988/89 ocean acoustic tomography was performed there to study the Greenland Sea gyre and deep water formation. Deep water formation simply means surface water being transported downwards into the ocean, this is important to drive the global ocean currents by thermohaline circulation. The study showed that the mixed layer at the surface forms in autumn. During winter, the region is covered by sea ice. In early spring when the sea ice vanishes, the layer gets thicker (up to 1.5 km). When the Polar day starts in late March the seasonal cycle starts again with another shallow mixed layer.

Worked examples

Example 1 — a first encounter with Greenland Plain

Start with the simplest possible case. Write down what Greenland Plain 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 Greenland Plain 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 Greenland Plain 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 Greenland Plain

In research: Greenland Plain 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 Greenland Plain 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: Greenland Plain is common in secondary-school and first-year university syllabi. It links to neighbouring topics Abyssal plains, Arctic stubs, Geography of the Arctic, so understanding it makes those chapters shorter.
In everyday life: Look for Greenland Plain 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.

Frequently asked questions

What is Greenland Plain in simple terms?

Why does Greenland Plain matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Greenland Plain?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
