Earth, Inside & Out

The Earth is divided into three layers

1. Crust 2. Mantle3. Core

Today we are going to learn about the center or core of the planet

http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Core-.mov




Core

i) Deep within the Earth is the core

ii) The core is made mostly of nickel & iron

iii) Twice as dense as the mantle.

Main source of heat that triggers the convection currents


The core is made of two layers

(1) Outer core: Liquid & is responsible for the Earth’s magnetic field.

Inner core: solid

Today we are going to learn another layer of the planet the Mantle

http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Mantle-.mov




Mantle

(1) Hotter and denser than the crust because the deeper you go inside the earth, the temperature & pressure increases.

(2) Made of solid rock.

The Mantle is made of two zones


Mantle Zones (a) Lithosphere (i) Thin, uppermost

part of the mantle; cooler & less rigid

(ii) Floats on the athenosphere, and slides around very slowly.

(iii) The upper part of the lithosphere melts rocks, forming a substance called magma.


Magma

1. Magma (melted rock) moves like hot oatmeal.

Uneven heating causes material in the mantle to constantly and slowly rise & fall in convection currents.

Convection Current: process by which hot fluid rises to the surface, and then sinks again, like soup being heated in a saucepan


(a) Asthenosphere

Hot, weak zone directly under the lithosphere

Flows at a very slow rate

Today we are going to learn about the last layer of the Earth, the Crust

http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Crust-.mov




Crust (1) This is the outermost

layer of the Earth. (2) This is the layer we walk

on. (3) It is a thick, rocky skin. (4) If we think of the Earth as

a billiard ball, this crust is as thin as a postage stamp stuck on a billiard ball.

(5) At its thickest, which is under mountain ranges, the crust is only about 35km (22mi) thick.


And what type of crust would you like with your Earth?

There are two types of crust


Continental Crust:

1. Makes up the continents

2. Contains light colored rocks such as granite.

3. Floats high on the mantle


Oceanic Crust

1. Makes up the ocean floor

2. Contains the dense rocks such as basalt

Thinner than the continental crust
