Hello there students.
00:01
Today we're going to be discussing about how do a shell volcano, a cinder cone, and a composed cone differ from one another, and how they are similar.
00:16
So let's just begin.
00:18
Let's discuss about the shield, i mean the shield volcano.
00:27
So for the shield volcanoes, um, well, they are they are filled with fluid basaltic well let's say the fluid basaltic magma often builds builds a slightly sloped you know 60 degree to 12 degree angle shield what else can we say about them they can be enormous yeah how enormous on up to 90 i mean up to 9 ,000 meters high what else can i bring about them how with the style of activity it's like with the activity it's like gentle it's like a gentle style of activity where some lava oh i don't know why i wrote down lova i mean lava um how fountains and with these type of um one of those like example of these where you can find these in like hawaii and um um iceland where they erupt regularly and the eruptions are usually gentle and everything is just gentle it's just like kind of just slow moving all of that and also how it's rarely life threatening even though it it can um oops even though it's rarely life threatening um the law have a flow occasionally, sorry, my pen, occasionally overrun homes and fillages, but it goes very slow.
04:49
But the flow is slow, so it's a very chill.
04:58
It's a very chill type of volcano.
05:01
So the shield volcano it's very chilled it's very chill not so scary and all that it's just it's just chill it's very calm takes this time so the next one we're going to talk about is the cinder cones and with the cinder cones what are they these are your small volcanoes that are composed of phyroclastic fragments and they usually form when large amounts of gas accumulates the rising magna.
06:37
And when the gas pressure builds sufficiently, an entire mass erupts explosively, curling cinders and molten, oh, magma, not la alpha, not bad, into the air.
07:35
And then they brought how particles then will fall back around the fint they also bring in to accumulate as small mountains of let me just keep writing over here how it accumulates as a small mountain of phyroclastic debris they're active only let me face it alive they're only active for a short time and the reason for that is when once the gas escapes escapes escapes the drapes the drugs driving force behind the eruption is gone.
09:36
And with these type of combs, they're usually are symmetrical and have a steep about 30 degrees.
09:59
And more than less, they're like, they can be between 300 meters to at a time.
10:12
You know some occasions 700 meters high and these cones they erodes easily and quickly because the priclactic fragments are not concrete together so oops try to reset okay so that's one thing we can add we can add um oops i mean cemented together and then finally we are going to talk about compost.
11:16
And compostite cones.
11:38
And compostite cones.
11:40
Sometimes they are called start -startocanals.
11:51
Probably said that wrong.
11:53
Which they usually form over a long period of time as a seat of lava flows and pyroclastic erupts and they bring up how the hard lava cover cover the loose iron classic materials protects it from erosion and what else can we ask about them oh the type of magma them the type of magma they are um riotite or just another way of saying granite granite so that's what we listed out about them...
