Rocks And how they're formed. By Levi Nattrass. Hi! I’m Mr. Convincer. Today, I’ll be convincing you that you know about rocks and how they’re formed, by teaching you!. That rock is under heat and pressure so… he will be a metamorphic rock.

Hi! I’m Mr. Convincer. Today, I’ll be convincing you that you know about rocks and how they’re formed, byteachingyou!

See that speck on top of the diagram? Look at the diagram and tell me where it would go and click the answer below, and if you get it wrong it will end the show! Sedimentary rocks are formed by layering of sediments, but it can’t do that without pressure. That's called cementation. Here’s a diagram on the layering. Small rocks Larger rocks
Now you're probably getting bored because I’m just teaching, so…SUPER Convincer!
Uh-o. From now on I am evil!! OUCH! I’m melting!!!
Well anyway, the diagram that I’m in is showing the parts of a volcano. There are two types of lava, a`a and pahoehoe. Pahoehoe is a watery lava that when it dries is a mass of billows and ropelike coils. A`a is a type of lava that is cooler and has a more gooeyness and when it dries it becomes a rough surface with weird, jagged chunks of lava. Well, I don’t like having one eye, but I’ll get used to it. Hey! Give me back my eye! Hu? Where am I, and what’s with all the writing?
Man! I hate having one eye. Well we have one more rock type to visit. Sedimentary! Hey what’s with the thing!?!
Hi, welcome to volcano world! Uhh… hi, um I’m a TV reporter and I got sucked in here. Can I get out of this place quickly because I don’t have that much time, so… hey there’s my eye!
The first layer is the crust. It is 6 miles deep The core is made of molten iron. The last layer is the core. It is made The mantle is the second layer of the earth and is made of magma. The third layer is the outer core, it is molten iron and magma.
I escaped volcano world. Well, sedimentary rocks are formed by layering and pressure of sediments but where do sediments come from? They come from other rocks like a metamorphic rock could get weathered away and become sediments and the wind or water decomposes the sediments into layers.
That right there is the rock cycle. Any rock can turn into any rock with the right stuff, like a igneous rock can turn into a metamorphic rock with heat and pressure. So that’s how rocks are made.
Well that covers the three types of rocks igneous, sedimentary, metamorphic and that volcano dudes can fly. Thanks for watching, bye!
