Deaest Volcanologists (live long and prosper..lol....*groan*) ::)

Ok...ewe got your four basic volcanos....Shield,Dome,Cinder cone and then ewe have a Stratovolcano

Here's one :




So there I was throwing twigs at the cow in the next field thinking that all volcanoes were just your bog standard lava erupting big bang pyroclastic flowing bit's of angry Earth zits !!....and then Daisy (the cow next door....original name eh ?) happens to mention the other types !!

well, I made my excuses about seeing a man about a dog and high tailed it back here to ask ewe all about the four different types of volcano....

can ewe help ?......yer can't let a bovine get the better of a Bovidae

What's the difference between the four volcanoes ?

Ahhhh, but were there only 4!

Why are shields so flat?
Basalt runs out, KERSPLAT!
Flowing like a liquid, it finds the easiest route
goes around obstacles, so it doesn't stick out.

Strato's are so big and tall
sticky lava and ash fall
Explosive blasts
Andesite clasts
Only found above subducting plates
blown apart then reincarnates

Cinder cones are made of scoria
That pop and sizzle in all its gloria
Volcanic fragments thrown into the air
Frozen into rocks whilst there
Fall nearby, all black and shiny
This is why most cones are tiny

Lava domes are too viscous
Protruding, never vicious
Given time, they can grow
At a rate that's always slow

Enormous are calderas and traps
you need to add them to your maps
And by far the most lava is sent
from the mid oceanic ridge vent

FANTASTIC !!

As a Brit I had to remember to treat the word 'route ' with the americanistic pronunciation and then the rest of the poem just exploded into place !!


WONDERFUL verse....
Spoken with ease and not terse
From them all down to zero
Describing Volcano !



YAYYYYYYY
