1
Have you ever picked up a rock and wondered, where did the even come from?
2
Rocks aren’t just...
3
rocks. They’re full of secrets!
4
And today, we’re learning how to read the stories that rocks tell.
5
What’s up, everyone?
6
My name’s MayNERD, and I’m teaming up with Nat Geo Kids for Earth Month to explore one of the coolest things on our planet...
7
rocks! Are you ready to become a rock detective?
8
Let’s dig in!
9
Believe it or not, almost every rock you find outside belongs to one of three big rock families.
10
First up...
11
igneous rocks.
12
These rocks begin as magma, deep inside the Earth.
13
When magma pushes up and erupts from a volcano, it’s called ‘lava.’ And when that super hot liquid cools down and hardens, it turns into solid rock.
14
That means igneous rocks were once melted lava from a volcano!
15
Pretty crazy, right?
16
If you’re trying to spot one, here are some clues to look for: You might see some tiny holes in the rock - those are air bubbles that got trapped as the lava cooled.
17
You may also notice some sparkly crystals.
18
That usually means the rock cooled slowly, giving the crystals time to grow.
19
You can spot igneous rocks in everyday places, like roads or sidewalks, or even in the granite on your kitchen counter.
20
Next, sedimentary rocks.
21
These rocks are made from teeny tiny pieces of other rocks.
22
Wind, rain, and rivers break big rocks into sand, mud, and pebbles.
23
Those little pieces travel around, then settle down and pile up in layers like a giant rock lasagna.
24
Over time, more and more layers stack on top.
25
The heavy weight pushes down with lots and lots of pressure.
26
A brand new rock is formed!
27
If you’re trying to spot one, look for layers stacked on top of each other.
28
You can often recognize sedimentary rocks by their texture.
29
Sandstone feels gritty or sandy when you touch it.
30
Limestone may have shell shapes or fossil marks inside, reminding us that area may have once been under water.
31
Sedimentary rocks are like Earth’s notebooks - each layer records what this place looked like long, long ago.
32
Maybe a river bed...
33
a beach... or even, an ancient ocean.
34
Last, but certainly not least, are metamorphic rocks.
35
These rocks used to be, well...
36
other rocks!
37
But deep underground, they were squeezed by intense heat and pressure.
38
They didn’t melt - they changed.
39
If you’re trying to spot one, look for wavy stripes or swirls like someone stirred the rock while it was soft.
40
You may have seen metamorphic rocks wthout even realizing it.
41
Marble is one.
42
It’s used in statues and buildings.
43
Slate is another.
44
It splits into flat sheets, and has been used for tiles and...
45
chalkboards.
46
Some metamorphic rocks are more than three billion years old.
47
This rock might’ve basically been a time traveler!
48
Now that you’re officially a rock detective, here is your Earth Month Mission.
49
Go outside and collect three different rocks.
50
Ask yourself - does it have layers like a stack of pancakes?
51
Is it speckled with shiny crystals?
52
Does it have swirls or stripes?
53
You might be holding a piece of an ancient volcano or the bottom of a long ago ocean!
54
