1 Earth’s Layers

2 Essential Questions: What are the main characteristics of the Earth’s layers? How can the Earth’s layers be illustrated?

3 Earth’s Crust Earth's Layers The outer layer of the Earth
Similar to the skin on an apple (thinnest layer) Made up of both continental (land)and oceanic crust(under the ocean) 5-50 km thick © KeslerScience.com

4 Oceanic Crust Earth's Layers
A thin layer of crust that overlies the ocean basins More dense than continental crust Mostly basalt rock Thinner that continental crust. (5-10km) Younger (newer) than continental crust © KeslerScience.com

5 Continental Crust Earth's Layers
Layer of rock which forms the continents Less dense than oceanic crust Mostly granite Thicker that oceanic crust Older than oceanic crust © KeslerScience.com

7 Lithosphere Earth's Layers
Solid outer section of the Earth, which includes the crust (rocky layer) Also, includes the cool, dense, rigid upper part of the mantle © KeslerScience.com

8 Quick Action – Earth's Layers
Draw and label a picture of the Earth’s lithosphere and asthenosphere in your INB’s. Lithosphere Asthenosphere © KeslerScience.com

9 Earth's Layers Mantle Largest layer of the Earth
Under the crust about 2,890km Composed of silicate rocks rich in magnesium and iron Intense heat causes the rocks to rise and then cool and sink. The process is called convection, which causes the crust to move. Average temperature 3000o © KeslerScience.com

10 Outer Core Earth's Layers
Liquid layer (magma) 2,300 km thick, second largest Composed of liquid iron and nickel Lies between inner core and mantle Because the magma moves around the inner core, Earth’s magnetic field is created. Average temperature 4000o -5000o © KeslerScience.com

11 Earth's Layers Inner Core A solid ball of metal 1,250 km thick
Made of solid nickel and iron So hot it melts everything in the outer core Spins at a speed faster than the Earth rotates Densest layer of the Earth Average temperature 5000o o © KeslerScience.com

12 Waves of energy caused by earthquakes and other rock movement
Earth's Layers What are seismic waves? Waves of energy caused by earthquakes and other rock movement Travel through some layers of the Earth Recorded with seismographs © KeslerScience.com

13 Earth's Layers Seismic waves are used to determine which layers of the Earth are solid or liquid. Some seismic waves cannot pass through certain layers giving us a clue to the layers composition. © KeslerScience.com

14 Check for Understanding
Can you… List the characteristics of each of the Earth’s layers? Illustrate the Earth’s layers? © KeslerScience.com
