Watts Point volcanic centre

Watts Point volcanic centre 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 Watts Point volcanic centre rather than just read about it. In short: The Watts Point volcanic centre is a small outcrop of Pleistocene age volcanic rock at Watts Point in British Columbia, Canada, about 10 kilometres (6 mi) south of Squamish and 40 kilometres (25 mi) north of Vancouver, and just north of Britannia Beach. It is the southernmost volcanic zone in the Squamish volcanic field and of the Garibaldi segment of the Cascade Volcanic Arc.

Key takeaways

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

Reference excerpt

The Watts Point volcanic centre is a small outcrop of Pleistocene age volcanic rock at Watts Point in British Columbia, Canada, about 10 kilometres (6 mi) south of Squamish and 40 kilometres (25 mi) north of Vancouver, and just north of Britannia Beach. It is the southernmost volcanic zone in the Squamish volcanic field and of the Garibaldi segment of the Cascade Volcanic Arc. The latest research indicates that it is most likely a subglacial mound. It comprises a continuous mass of sparsely porphyritic highly jointed dacitic lava overlying the mid-Cretaceous Coast Plutonic Complex and overlain locally by clay and of glacial till. The volcanic outcrop at Watts Point extends from below the present sea level up the side of a steep slope over 240 metres (800 ft). The outcrop is less than 1 kilometre (0.6 mi) long, with an area of about 0.4 square kilometres (0.2 sq mi) and an eruptive volume of roughly 0.02 cubic kilometres (0.0048 cu mi). The location is heavily forested, and the BC Rail mainline passes through the lower portion of the outcrop about 40 m (130 ft) above sea level. Two railroad track ballast quarries, one near the middle and the other near the upper edge, provide the best exposure of the interior of the lava mass. BC Highway 99 climbs over the eastern shoulder of the complex before descending to the area of the Stawamus Chief and Murrin Park, south southeast of Squamish.

Worked examples

Example 1 — a first encounter with Watts Point volcanic centre

Start with the simplest possible case. Write down what Watts Point volcanic centre 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 Watts Point volcanic centre 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 Watts Point volcanic centre 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 Watts Point volcanic centre

In research: Watts Point volcanic centre 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 Watts Point volcanic centre 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: Watts Point volcanic centre is common in secondary-school and first-year university syllabi. It links to neighbouring topics Garibaldi Volcanic Belt, Pleistocene British Columbia, Pleistocene volcanoes, so understanding it makes those chapters shorter.
In everyday life: Look for Watts Point volcanic centre 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.
