Layers of Earth
Crust Outermost layer Thinnest under ocean Thickest under continent Crust + top of mantle = Lithosphere
Crust density Least dense overall layer Oceanic crust (basalt) is more dense than Continental Crust (granite)
Crust composition Solid rock—mostly silicon and oxygen Oceanic crust—basalt Continental crust--granite
Mantle Position Middle layer, thickest layer Top portion called the asthenosphere
Mantle Density Density increases with depth of increasing pressure
Mantle Composition Hot softened rock Contains iron (Fe) and magnesium (Mg)
Core position Inner layer Consists of the outer and inner core
Core density Heaviest material; most dense layer
Core composition Mostly iron and nickel Outer core—slow flowing liquid Inner core--solid
Thickness of Layers Crust: (continental) 22-43 miles thick (1 % of Earth’s volume) Mantle: 1,800 miles thick (84% of Earth’s volume) Outer core: 1,400 miles thick Inner core: 790 miles thick
Density increases the deeper in Earth you go. This is because as you go deeper into the earth, pressure, and temperature increase. The inner core.
Earth’s Layers. Earth is divided into 3 basic layers: 1. Crust 2. Mantle 3. Core These layers are then subdivided into smaller layers.
Inside the Earth. Composition (What it is made of) Crust Mantle Core.
Composition (What is it made of?) Divided into 3 layers: Crust Mantle Core.
Ch. 7.1: Inside the Earth. Earth’s layers The Earth is divided into three layers 1.) Crust 2.) Mantle 3.) Core Crust and Mantle are made of less dense.
-Enter -Get out your INB -Have something to write with -Make sure you have your Earth Layers Foldable Do These Things When You Enter the Room This is what.

1._____heat from inside the Earth 2._____type of resource minerals and metals are 3. _____cutting down all of the trees in an area 4._____crops that replenish.
Earth’s Layers Standard: 2 Describe the layers of the earth, including the lithosphere, the hot convecting mantle, and the dense metallic core.
Structure of the Earth. What are the layers of the Earth Crust Thin layer of rock Surrounds Earth like a shell surrounds an egg Two types of crust.
Journey to the Center of Earth. Layers of the Earth Crust Lithosphere Asthenosphere Mantle Outer Core Inner Core.
Earth Layers. Inner Core Made mostly of iron and nickel Dense ball of solid metal due to intense pressure Very hot and very dense 1,216 km thick.
What are the three layers of the Earth? What are the characteristics of each layer?
Layers of the Earth. Composition (What it is made of) Inner Core Outer Core Mantle Crust.
Earth's Interior Summarize the three layers of Earth- crust, mantle, core- on the basis of relative position, density, and composition.
Inside the Earth Layers that Make Up the Earth. Composition (What it is made of) Crust Mantle Core.
Layers of the Earth. Directions Take detailed notes about the different layers of the earth. Be sure to include: A Title Subtitles For Each Topic Drawings.
6-70 km thick 6-70 km thick Very light; only 1% of Earth’s total mass Very light; only 1% of Earth’s total mass Made up of rock Made up of rock Two types.
Earth’s Composition Lesson 1: Layers of the Earth SC.7.E.6.1 Student will be able to describe the different layers of the earth.
Earth’s Inside Earth Pages Inside Earth Pages Interior.
Inner Core – the dense, solid center of the earth, formed mostly of iron and nickel Outer core – the liquid layer of the earth’s core that surrounds.
Layers of the Earth. The Inner Core Composition: iron and nickel Depth Range (Km): 5150 Km State of Matter: solid Temperature: º C. Density:
The Inner Core The deepest layer in Earth is the inner core. It is located at the center of the Earth because it contains the densest material of all.
The Earth’s Layers Layers. Students will … illustrate the structural layers of Earth, including the inner core, outer core, mantle, crust, asthenosphere,
Layers of the Earth. What Are The Earth’s Layers ? Inner Core Outer Core Mantle Crust.
Chapter 5.1 Notes Earth’s Interior. Exploring the Earth Geologists use two types of evidence to learn about the Earth’s interior: -direct evidence from.
Earth’s layers core, mantle, crust. CORE Corecenter of earth; divided into outer core and inner core.

Earth on the Move Earth Structure & Plate Tectonics Notes.
Inside the Earth The Geosphere. Composition (What it is made of) Crust Mantle Core –Inner –Outer.
1.Which branch of Earth Science would study earthquakes? 2.Which branch of Earth Science would study hurricanes? 3.Which branch of Earth Science would.
Earth’s Composition Standard S6E5. Students will investigate the scientific view of how the earth’s surface is formed. a. Compare and contrast the Earth’s.
Compositional Layers divided into 3 layers based on elements that make up each layer.
E ARTH ’ S L AYERS Notes. E ARTH ’ S L AYERS The Earth can be divided into different layers based on either composition or based on their different physical.
Earth’s Layers Crust Thin rigid layer that surrounds the earth Two types of crust Continental – granite Oceanic – basalt Oceanic Crust is more dense.
Layers of the Earth. Exploring the Layers Seismic Waves – When waves change we know the layers are different.
Earth has 2 types of layers or zones: - Compositional: what each layer is made of - Mechanical or Structural: physical characteristics about each layer,
There are 2 ways to divide the layers of the earth..... Physical layers Compositional layers.
Layers in Order 1. Crust 2. Mantle Lithosphere Asthenosphere 3. Lower Mantle 4. Outer Core 5. Inner Core.
Warm-up Take out your earth’s layers foldable. Your homework is now due tomorrow. Keep your homework and DO NOT turn it in. Take a notes page from the.
