The Theory of Plate Tectonics
Earth’s crust is broken into about 19 pieces that are in constant motion
4
Warm up! How are the earth’s layers similar to an egg?
5
Earth’s Layers How are the earth’s layers similar to an egg?
Shell = crust Egg white = mantle Yolk = core
6
Big book pg. 124 Small book pg. 6
S1: Inside the Earth Big book pg. 124 Small book pg. 6
7
The 3 Main Parts 1. Crust 2. Mantle 3. Core
8
The Crust Outer layer (shell) Thinnest layer Solid 2 types of crust
Oceanic Crust (very dense) Continental Crust (less dense)
9
The Crust Outer layer (shell) Thinnest layer 2 types of crust
Oceanic Crust (very dense) Continental Crust (less dense)
10
Less Dense > More Dense >
12
The Mantle Middle layer (egg white) Thickest Layer
Solid, but able to flow slowly
13
The Core Center (like the yolk) Hottest part, mostly made of iron
Has 2 parts Liquid outer core Solid Inner core
14
The Core Center (Like the yolk) Hottest part, made of mostly iron
Has 2 parts Liquid outer core Solid Inner core
15
Layers of the Earth Crust Mantle Core Directions:
Put your name at the top Label the parts of the Earth (Crust, Mantle, or Core) 3. Use the Color Code to color each part of the Earth EXT. Read Big Book pgs. 124 or Small book pg. 6
16
To Do Finish ¨Inside Earth¨ worksheet and paste into your science notebook Define following key terms: Pressure Basalt Granite Lithosphere Asthenosphere
17
Exploring Earth Why is it difficult to determine Earth´s structure?
18
Exploring Earth Why is it difficult to determine Earth´s structure?
Too much pressure Too much heat
19
How did scientists know what is inside of earth?
20
How did we figure out what’s inside of earth?
1. Rock samples from volcanoes
21
How did we figure out what’s inside of earth?
Rock Samples from Volcanoes Seismic Waves from Earthquakes
