Homeschooling is still what we are doing around here ..
This week we are working on layers of the earth.
I ran into this cute little rap to help get the facts down pat!
There was no credit given.. but big thanks to whomever wrote it!
LAYERS OF OUR PLANET
Throw your hands up for the layers of the earth
Throw ‘em up for what’s below the surface
Throw your hands up, and let’s discuss
The inner core, outer core, mantle, and crust
The layer we’ll discuss first
Is the central inner core, in the center of the earth
A solid ball buried below the dirt
We believe it’s primarily metallic iron
You could never take a trip to the inner core, right?
The heat will burn you up, 9,000º Fahrenheit
4,000 miles below the Earth’s crust
One down three to go y’all.
1,800 miles from the tip top
The outer core is hard at work and it don’t stop.
It’s busy spinning around the inner core, and listen,
This steady movement causes Earth’s magnetism.
Ranging from 4 to 9,000 degrees,
It contributes 1/5 of the heat flowin’ to you and me.
It’s liquid metals that violently flow
So let it settle… and when you’re ready let me know. Just…
The mantle layer is the largest of the class.
About half of our planet’s mass.
The mantle is composed of very hot dense rocks,
That move and flow, always on the go, they never lock,
Never stop, and they’re responsible for tectonic shift
Please believe the Earth’s plates are adrift
It’s pretty thick and the heat is awesome
1,600 at the top, 4,000 at the bottom
The continental crust’s surface is where we breathe
A lot of rock up to 25 miles deep.
The oceanic crust is next door
It’s 3-5 miles thick just below the ocean floor.
Earth’s surface: 70% H20.
Where do you get all that water? Salty sea flow,
fresh water’s in the glaciers, ice caps, and snow.
