Baker 7th grade science 2003-2004

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

Baker 7th grade science 2003-2004

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

Baker 7th grade science 2003-2004

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

Baker 7th grade science 2003-2004

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

Baker 7th grade science 2003-2004

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.

Baker 7th grade science 2003-2004

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

Baker 7th grade science 2003-2004

(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

Baker 7th grade science 2003-2004

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.

Baker 7th grade science 2003-2004

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

There are two types of crust

Baker 7th grade science 2003-2004

Continental Crust:

1. Makes up the continents

2. Contains light colored rocks such as granite.

3. Floats high on the mantle

Baker 7th grade science 2003-2004

   Oceanic Crust

1.       Makes up the ocean floor

2.     Contains the dense rocks such as basalt

Thinner than the continental crust
