Homeschooling, it is still our thing...


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

Chorus

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



Verse I

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…



Chorus



Verse II

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.
