Layers of the Earth

Chorus

Throw your hands up for the layers of the

earth

Throw em up for whats below the surface

Throw your hands up, and lets discuss

The inner core, outer core, mantle, and crust

Verse I

The layer well discuss first

Is the central inner core, in the center of the

earth

A solid ball buried below the dirt

We believe its primarily metallic iron

You could never take a trip to the inner core,

right?

The heat will burn you up, 9,000 Fahrenheit

4,000 miles below the Earths crust

One down three to go yall.

1,800 miles from the tip top

The outer core is hard at work and it dont

stop.

Its busy spinning around the inner core, and

listen,

This steady movement causes Earths

magnetism.

Ranging from 4 to 9,000 degrees,

It contributes 1/5 of the heat flowin to you

and me.

Its liquid metals that violently flow

So let it settle and when youre ready let me

know. Just

Chorus

Verse II

The mantle layer is the largest of the class.

About half of our planets mass.

The mantel is composed of very hot dense

rocks,

That move and flow, always on the go, they

never lock,

Never stop, and theyre responsible for

tectonic shift

Please believe the Earths plates are adrift

Its pretty thick and the heat is awesome

1,600 at the top, 4,000 at the bottom

The continental crusts surface is where we

breathe

A lot of rock up to 25 miles deep.

The oceanic crust is next door

Its 3-5 miles thick just below the ocean

floor.

Earths surface: 70% H20.

Where do you get all that water? Salty sea

flow,

fresh waters in the glaciers, ice caps, and

snow.

THE EARTH

Earth is the planet on which we live. As you know, the Moon goes round the Earth.

Exploring Earth from Space:

- Can you see the Oceans?- Can you see the Clouds?- Can you see the Continents?

Size of the Sun as compared to Earth

The Sun has a diameter of about 1,392,000 km.

Earth's diameter is 12,742 km. The diameter of

the Sun is thus 109 times as great as the

Earth's diameter. In other words, you could line

up 109 Earths across the Sun.

Earths Four Spheres:

The Earths four parts are called the geosphere, hydrosphere, atmosphere, and biosphere.

GEOSPHERE

Geosphere refers to the solid parts of the Earth. It has three layers: core, mantle and crust.

The Earths crust: The thick surface of the Earth. The crust is underlain by the mantle. The

crust is in contact with the atmosphere.

It has two parts: The oceanic crust and the continental crust.

The Oceanic Crust is the part of Earth's that surfaces in the oceans.

The Continental Crust is the layer which form the continents.

Mantle: the part of the Earth that is deep below the surface and surrounds the CORE (=centre).

It is divided into two parts:

Upper mantle: It is formed by solid materials and magma (hot liquid rock inside the Earth)

Lowe mantle: It is formed by solid materials.

Core: The central part of the planet. It is divided into two parts:

Outer core: The outer core of the Earth is a liquid layer above the solid inner core.

Inner core: It is formed by solid materials.

HYDROSPHERE

Hydrosphere: Is the "water sphere" that includes all the water of the earth system.

The hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes,

and rivers. The hydrosphere covers about 70% of the surface of the Earth and is the home for

many plants and animals.

ATMOSPHERE

Atmosphere: It is the air round the Earth.

The atmosphere of our home planet is made up

of three primary gases. These gases are

oxygen, nitrogen, and argon. In addition to

these three gases, there are many other gases

in the atmosphere, in trace or small amounts.

Additionally there are small particles, or

particulates floating in the atmosphere, such

as dust, water, and pollen.

The Layers of Our Atmosphere

In order to better understand our atmosphere scientists have divided it into several layers. These

layers are divided based on the characteristics of the gases found at that height. Each layer in our

atmosphere is referred to as a sphere.

The first layer of the atmosphere is fortunately not made out of cake, but rather it is made out of

the gases that we breathe everyday. This layer is called the troposphere. The troposphere is the

layer that we live Atmosphere phenomenon: Wind and Rain

How does rain form?

Water droplets form from warm air. As the warm air rises in the sky it cools. Water vapour

(invisible water in the air) always exists in our air. Warm air holds quite a bit of water. For example,

in the summer it is usually very humid. When enough of these droplets collect together, we see

them as clouds. If the clouds are big enough and have enough water droplets, the droplets bang

together and form even bigger drops. When the drops get heavy, they fall because of gravity, and

you see and feel rain.

What causes rain?

When clouds develop or rain occurs, something is making the air rise. Several things can make this

happen. Mountains, low-pressure areas, cold fronts, and even the jet stream (small rivers).

How big are raindrops?

Raindrops are much smaller than we think! They are actually smaller than a centimetre. Raindrops

range from 1/100 inch (.0254 centimetre) to 1/4 inch (.635 centimetre) in diameter.

BIOSPHERE

Biosphere: The biosphere is the life zone of

the Earth and includes all living organisms,

including man, and all organic matter that has

not yet decomposed.

What is the Biosphere?

All regions of the Earth those are capable of supporting life.
