00:00:00
hello and welcome to geology of
00:00:02
minecraft episode one
00:00:03
my name is nice and i'm a geologist
00:00:06
minecraft has many geologic materials
00:00:08
and processes
00:00:09
and in this episode we're going to
00:00:10
briefly talk about the materials
00:00:12
and classify them into groups in later
00:00:14
episodes we'll look at these in all in
00:00:16
more detail
00:00:18
so let's head over to our geologic
00:00:20
timeline and we'll update our
00:00:22
exhibit list
00:00:25
see you have to
00:00:29
to geology which i covered in episode
00:00:31
zero
00:00:32
and then
00:00:37
geologic materials good it fits all
00:00:40
right
00:00:40
and then we're gonna for this one we're
00:00:44
not going very far we're going to
00:00:47
uh just teleport over here
00:00:52
and just a note i'm recording this as
00:00:54
the 1.17 snapshots are coming out
00:00:56
so which add a whole lot of new
00:00:59
materials
00:01:00
to the game uh geologic materials and
00:01:03
i've already made a video about amethyst
00:01:06
geodes
00:01:07
but i i'm going to wait until the full
00:01:09
1.17
00:01:11
release actually comes out and then i'll
00:01:13
i'll talk about those
00:01:14
in in other episodes so you won't find
00:01:16
any of those new materials
00:01:18
in this episode the first group we're
00:01:21
going to talk about
00:01:22
is rocks these are geologists classify
00:01:25
rocks
00:01:25
as naturally formed solid material that
00:01:28
is a collection of minerals
00:01:31
and then we further classify them by how
00:01:34
they are formed
00:01:35
and the minerals that are present in
00:01:37
them
00:01:39
it might seem weird in minecraft but we
00:01:41
only have
00:01:42
uh seven rocks and i'm not gonna count
00:01:45
other things like
00:01:46
steps and slabs those are the same
00:01:48
minerals just cut differently
00:01:49
but these are all the rocks we have we
00:01:52
have four
00:01:53
igneous rocks which are formed from
00:01:55
volcanic
00:01:56
processes these are or volcanic or
00:02:00
i should say just igneous you can learn
00:02:02
about the rock cycle and types of rocks
00:02:04
uh in episode zero i talked
00:02:06
briefly about that but we have andesite
00:02:10
diorite
00:02:10
granite and basalt and then we have
00:02:13
those are the igneous and we have a
00:02:15
stone which is a odd case
00:02:18
we'll talk about it in its own video
00:02:20
probably
00:02:21
and then we have sandstone and those are
00:02:24
all the actual
00:02:25
rocks we have in minecraft
00:02:28
next up we have sediments
00:02:32
now these are natural materials
00:02:36
get used to hearing natural materials
00:02:38
all of these materials or things like i
00:02:40
said
00:02:41
that that definition normally starts
00:02:44
with
00:02:44
natural something but these are natural
00:02:47
materials that have been broken down
00:02:49
through
00:02:50
the process of weathering and erosion so
00:02:52
wind and rain and
00:02:53
freezing and all of that stuff and so
00:02:56
these aren't stone which are solid
00:02:59
pieces that you can pick up like if you
00:03:01
try to pick up sand you get a pile of
00:03:03
sand in your hand
00:03:04
or you get a lump of clay it's not
00:03:07
something that is
00:03:09
stuck together so
00:03:12
but these are sediments that can be
00:03:15
distributed by
00:03:17
gravity water ice
00:03:20
wind and then eventually they come to a
00:03:22
low lying area they get washed out to
00:03:24
sea
00:03:25
and they uh
00:03:28
gently go down to rest and then they are
00:03:31
sediments and eventually they can
00:03:32
turn into stone sand can turn into
00:03:35
sandstone
00:03:36
and uh clay uh
00:03:39
can turn into eventually things like
00:03:42
slate and
00:03:43
things like that but um
00:03:46
these are not stones
00:03:49
uh even cobblestone uh
00:03:52
it's made up of rocks
00:03:55
but it is itself is is not a rock type
00:04:00
and so we have our gravel cobblestone
00:04:03
clay and r2 sand colors that we have
00:04:07
like in the game
00:04:11
next is ores
00:04:14
so we classify this guess it that's
00:04:17
right
00:04:18
a natural material that has an
00:04:21
element or a mineral that we can that
00:04:24
can be mined
00:04:25
or sold and a profit made from it
00:04:28
so it it solely has to deal with with
00:04:31
money
00:04:32
if something has gold in it and
00:04:35
we it but doesn't have enough to be
00:04:38
worth it like if it cost a hundred
00:04:40
dollars to get 10 dollars of gold out of
00:04:42
the ground
00:04:43
then we don't consider an ore an ore
00:04:45
means that it's
00:04:47
economically viable we can we can make
00:04:50
money off of it
00:04:51
the and then the ores in minecraft uh
00:04:55
that i have right here these are
00:04:57
representative of of real ores but um
00:05:00
not really that great there's a lot can
00:05:03
be a lot to be desired with how
00:05:04
ores are presented and that'll be again
00:05:07
talked about in their their own episode
00:05:10
next up is minerals uh
00:05:13
so i have these blocks here of of uh
00:05:16
minerals in minecraft but
00:05:18
we have diamonds uh emerald ignore all
00:05:21
this stuff that's from building things
00:05:23
lapis and nether quartz and
00:05:27
it's really i'm just going to call it
00:05:28
quartz
00:05:30
and so these are minerals that we have
00:05:32
and we define
00:05:33
a mineral as a chemical solid
00:05:37
that has a natural that is naturally
00:05:39
generated
00:05:40
and it's a repeating structure so
00:05:43
something like salt uh that
00:05:46
is one of the few minerals we can eat
00:05:48
out of the ground
00:05:50
uh it is the sodium and chloride
00:05:53
and it repeats over and over in a
00:05:56
structure
00:05:57
that makes it a mineral
00:06:01
and so rocks are made up of minerals
00:06:06
but a mineral is like a single component
00:06:09
of
00:06:10
of a rock and you can have rocks that
00:06:12
are
00:06:13
all one mineral like a marble
00:06:16
is all calcite it's that's really the
00:06:19
only mineral
00:06:20
present in it it's 100 calcite but
00:06:24
it is made up of minerals still
00:06:28
next up
00:06:33
we have soils a lot of people that
00:06:36
aren't familiar with geology might not
00:06:38
think of this as part of geology you
00:06:41
know most people think of geologists as
00:06:43
looking at rocks or something but
00:06:46
soil is a very important part of geology
00:06:51
and we define it as it's defined
00:06:54
as you can call it dirt or soil most
00:06:56
geologists call it soil
00:06:58
but is it a combination of minerals and
00:07:01
organic matter
00:07:02
so in the minecraft blocks we have these
00:07:04
little specks of gray they probably
00:07:06
represent little stones
00:07:07
and things like that but you have some
00:07:09
organic matter there you have something
00:07:11
some plant material or something that's
00:07:13
breaking down
00:07:14
and that provides nutrients for further
00:07:16
things to grow on
00:07:19
now we get into the semi-weird uh
00:07:22
categories i made up
00:07:25
so we have liquids in liquids and
00:07:27
non-rocks
00:07:28
i just kind of made this group these
00:07:31
together because it was convenient for
00:07:32
me
00:07:33
uh this isn't really like a formal
00:07:34
classification
00:07:36
um we have uh magma and we have lava in
00:07:39
the game
00:07:40
but in real world uh there's really no
00:07:43
difference between these two
00:07:45
except that lava is exposed on the
00:07:48
surface
00:07:49
and so uh magma is underground
00:07:52
and then as soon as it is exposed like
00:07:55
on the surface through a volcano
00:07:56
it's lava and and they can be chemically
00:08:00
exactly the same they're both uh like in
00:08:03
a liquid state
00:08:04
like this but in minecraft we have like
00:08:07
these different blocks
00:08:08
and that's just for game uh game
00:08:10
interest and things like that
00:08:12
i have obsidian here you might think
00:08:14
obsidian is
00:08:15
a rock but it is not a rock is made up
00:08:18
of minerals
00:08:20
and there are no minerals in obsidian
00:08:23
obsidian forms when you cool
00:08:26
uh lava or magma like very quickly
00:08:30
and minerals don't have a time to grow
00:08:32
crystals don't have a time to grow
00:08:34
and so it is a glass it is
00:08:37
it is we classify it geologically as a
00:08:40
glass it is
00:08:41
it is not a technically a rock
00:08:44
and then we have water which is like
00:08:48
very important it drives a lot of the
00:08:50
processes on on the planet
00:08:52
but um let's see something that
00:08:55
is not common uh water actually makes
00:08:59
rocks melt at a much lower temperature a
00:09:03
lot of magma
00:09:04
has some like a small amount of water in
00:09:06
it and a very small
00:09:08
amount of water in a in a
00:09:11
in a rock that is that is heated can
00:09:13
reduce its melting point by
00:09:15
by by like hundreds of degrees
00:09:22
let's see next we're going to talk about
00:09:25
snow
00:09:25
and ice so this will be
00:09:29
a little bit weird i know i already
00:09:30
covered minerals and rocks
00:09:32
but technically that's what these are
00:09:36
also snow is frozen water
00:09:40
it is a repeated structure of h2o it is
00:09:43
a
00:09:43
mineral so when it snows it's raining
00:09:46
minerals down
00:09:47
on our heads and then uh
00:09:50
you can compact snow and glaciers
00:09:54
and they form uh
00:09:57
dense ice we have packed and and blue
00:09:59
ice
00:10:00
and then we also just have regular ice
00:10:01
with which is collections of ice
00:10:04
crystals
00:10:05
and by definition this is a rock
00:10:09
um so ice uh
00:10:12
is a rock and snow is a mineral
00:10:16
very strange to think that we have rocks
00:10:18
that come and go
00:10:20
if you live in a cold and cold
00:10:21
environment on earth that we
00:10:23
uh get to see rocks form and melt in
00:10:26
front of our eyes all the time but
00:10:27
uh that's that's really what they are
00:10:31
so next up we have a group called
00:10:35
yes but no these are blocks
00:10:38
that have names that mean something in
00:10:42
real life but they
00:10:44
represent something different than than
00:10:45
what's in minecraft
00:10:47
like we have bedrock in
00:10:50
in geology it's a thing that we have but
00:10:53
um it's not you know at the bottom of
00:10:55
the world um
00:10:57
so but there is a thing called bedrock
00:10:58
and it means something in geology
00:11:01
uh we have well this is
00:11:05
a calcite block but the way we use it in
00:11:07
minecraft is
00:11:08
you know more like a marble column we
00:11:11
can carve it and you know make columns
00:11:12
and things like uh
00:11:14
you know greek uh structures and things
00:11:16
like that
00:11:18
we have bones and fossils and things but
00:11:21
they aren't obviously not in block form
00:11:23
but
00:11:24
they the way that fossils are found in
00:11:27
minecraft
00:11:28
are different from how they're found in
00:11:31
in real life and then um terra cotta
00:11:35
is a man-made product but
00:11:40
we have terra cotta
00:11:43
forming in these uh mesa biomes
00:11:47
in minecraft and and that's
00:11:48
representative of
00:11:51
um a geology term would be paleosols or
00:11:55
like ancient soils
00:11:56
and things um but so they're they're
00:11:59
representing something in in
00:12:01
found in real life but the names that
00:12:03
they're used for them are
00:12:05
are something entirely different so
00:12:07
we'll get into that more in their
00:12:09
their own episodes and then
00:12:13
lastly we have just know
00:12:18
things that might appear
00:12:21
that they would be real but but not
00:12:24
i mean uh you know we
00:12:28
probably the best one here is the
00:12:30
prismarine
00:12:31
which sounds like a geology rock
00:12:35
it um there are some other minerals and
00:12:38
things like aquamarine that sound
00:12:40
you know close to it but there's nothing
00:12:42
like that we don't have any redstone in
00:12:44
real life there's no ancient debris
00:12:47
there's not black stone uh which you
00:12:50
know seems like it would be like a an
00:12:51
igneous uh
00:12:53
rock possibly you know obviously the
00:12:56
gold
00:12:57
oars that we have in you know the nether
00:13:00
and black and gilded black stone aren't
00:13:02
aren't real
00:13:04
and uh the quartz uh another quartz also
00:13:08
obviously not real um but
00:13:11
yeah that's that's those are the
00:13:14
you know there's lots and then there we
00:13:16
have lots of other blocks in minecraft
00:13:17
that just
00:13:18
you know not not found in real life and
00:13:21
not including you know
00:13:22
natural other natural materials like the
00:13:24
the wood and all that stuff because
00:13:27
i'm a geologist not a biologist
00:13:30
so that's everything we're going to talk
00:13:32
about in this episode of geology of
00:13:35
minecraft
00:13:36
in the next episode i'm i haven't really
00:13:38
decided i might talk about
00:13:40
stone or i might talk about obsidian or
00:13:43
maybe both i'm not sure
00:13:44
how long doing that is going gonna take
00:13:47
but
00:13:48
anyway uh thanks for watching and until
00:13:50
next time
00:13:51
uh take it easy
