About volcanoes and volcanism notes
GoConqr OriginalUsing Volcanoes and Volcanism notes
These notes cover eruption types, volcanic products, hot spots and case studies. Start with The Geography Of Volcanoes for an introduction to volcanic features. Then read Types of eruption to compare the examples described there.
For a closer look at volcanic material, Products of Volcanoes includes volcanic gases. Where to find the pyroclasts looks at the distribution of material by grain size.
Turn reading into revision
As you read, make a short summary of each note in your own words. For case-study practice, use Mount St. Helens alongside the notes on the formation and impacts of Yellowstone super volcanoes. Compare the topics each note covers and return to any details you want to review.
When you want to see connections between ideas, switch to a mind map on the unit page. Use flashcards for key terms or a quiz to check your recall. Pick a note and make a start.
Frequently asked questions
Which note is a good place to start?
The Geography Of Volcanoes is a useful starting point because it introduces volcanic features. You can follow it with Types of eruption to compare the examples described there, then choose a case study such as Mount St. Helens for more focused reading.
What topics do these notes cover?
The notes include volcanic gases, pyroclasts, hot spots and mantle plumes, eruption types and case studies. For example, Where to find the pyroclasts discusses the distribution of material by grain size, while Products of Volcanoes includes a section on volcanic gases.
Are these notes free to use?
Yes. Every note listed here is free to open and study without an account. The resources were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
Who are these notes for?
The collection is mostly suited to school-level study. School students can use the notes to revise eruption types, volcanic products and case studies. Teachers can use them as ready-made material when covering those topics. The collection also includes material relevant to GCSE Geography.
