Seismic “Sonar”

Lithosphere “Rock Bubble” Asthenosphere “Putty Bubble” Crust Mantle Outer Core Inner Core

Crust – Thinnest layer made of rock. Oceanic crust is mostly basalt and is 5-10 km thick. Continental crust is mostly granite and is km thick. How we know: We live on it. Mantle – Thickest layer (makes up the bulk of the Earth’s mass and volume). Made of molten rock (magma). How we know: Magma sometimes comes up from the mantle at volcanoes, s and p waves travel through the mantle.

Outer Core – A layer of liquid iron and nickel. How we know: Liquid because s-waves are blocked in this region, iron and nickel because the earth has a magnetic field and their needs to be something very dense inside based on the density of the rocks in the crust and the overall density of the Earth. Inner Core – A layer of solid iron and nickel. How we know: Solid because p-waves are blocked in this region, iron and nickel because the earth has a magnetic field and their needs to be something very dense inside based on the density of the rocks in the crust and the overall density of the Earth.

The Lithosphere is made up of the Crust and the solid upper portion of the Mantle. The Lithosphere is what the tectonic plates are made of. The Asthenosphere is the putty-like upper portion of the Mantle that the tectonic plates “slide around on”.

1. Obtain a one meter long piece of register tape. 2. On one side of the paper near the end make a dot and label this as Earth’s center. This dot will represent the center of the earth. You will use this dot to make all of your measurements. 3. Measure 17 cm from earth’s center, draw a line across the paper and label the space below the line as Inner core. 4. Measure 46 cm from earth’s center, draw a line across the paper and label the space below the line as Outer core. 5. Measure 84 cm from earth’s center, draw a line across the paper and label the space below the line as Mantle. 6. Measure 88 cm from earth’s center, draw a line across the paper and label the space below the line as Asthenosphere/ upper mantle. 7. Measure 90 cm from earth’s center, draw a line across the paper and label the space below the line as Lithosphere/ Crust. This includes both the ocean floor, and land surface. 8. Measure 90.3 cm from the earth’s center, draw a line across the paper and label the space below the line as Earth’s surface. 10. Most people think that the atmosphere is quite thick. All of the weather happens here, and the clouds look so far away that it must be quite thick. To find out how thick it is measure 90.7 cm from the earth’s center, draw a line across the paper and label the space below the line as Atmosphere. This is the thickness of the atmosphere, but you would suffocate long before you reach this height. In fact, the thickness you can breathe in is about as thick as your pencil lead.
