Rocks and Minerals

Hi I am Tessa Welcome to Fun Science Demos Today the big idea is: what are rocks and minerals Hmm, we know we live on Earth Earth is made up of three different types of matter. The first one: air It is a gas It is all around us The second one: the ocean It is a liquid Water it is everywhere And the third one: Well we live on
continents They are solid and they are made of rock And under those continents and under that water is more rock So I have four different rocks here Let us take a closer look at them Start with this one it is different Lots of
different colors in this rock And and this one right here it feels interesting And this one
is well it is solid But they all were And this one has got lots of little
different pieces Well what is this made of Let us take a closer look at this interesting rock
right here When I look closely at this rock I see many different colors How does it get those colors Well it has got black it has got a little bit of
gray it has got this pinky beige color This is made up of a lot of different things And this rock can be found all over the
world If I were to dig right under me in
North America I would find this rock If I were to dig in Africa I would find this rock If I were to dig under any continent I would find this rock It is pretty famous This rock is called granite Through science we have discovered that rocks are made of two or more minerals See this black mineral right here That is right in here that is those black pieces This white one well that is in here too And the brownish pinkish color that is here too Pretty awesome But how did this mineral and this mineral go together to make this It is not happening Through science we have discovered that these three minerals can melt and go from a solid to a liquid And well where does that happen Deep inside the earth Here is a picture of deep inside the earth and those liquids mix together And those minerals get all mixed up and as they cool they change and they turn into this: rock Granite makes up our continents And our continents are on top of the earths crust. And so are the oceans they are on top of the
earths crust too And what is the earths crust Another rock basalt Wow! Science is so cool. If you want to learn more about rocks and
minerals check out our links in the video description Thanks
