LAYERS OF THE EARTH
We all know how the Earth's surface looks like. But what is inside? Why do scientists say that the Earth is like a giant peach or apple, even like an egg?? Long time ago, people thought that you could drill a hole from the United States all the way to China. Could that be possible? Other people said that if you go to the center of the Earth, you will find the lost world, a place full of dinosaurs and magic creatures. What do you think?? What is the center of the Earth made of?

====1. Read the paper you were given carefully. You must complete all of the questions.====

====2. Read the document carefully and make sure you write your names.====

Source ||= 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 mantel 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. ||
