Inside the Earth.  At earth’s center is the inner core.  The inner core is composed of nickel and iron in solid form.  The depth from the surface is.

Compositional Layers divided into 3 layers based on elements that make up each layer

Journey to Center of the Earth

Draw a model of the inside of earth On loose leaf paper Art supplies available

THE LAYERS What was right about your model? What was wrong about your model?

CRUST What we know? Rocky- mainly silicates (quartz, feldspar) Brittle Broken into pieces (plates) Continental- granite (less dense)- thicker Ocean- basalt (more dense)-thinner

CRUST How do we know it? Direct samples ( drill cores) sonograms

Drill cores Deepest 12 km Tried to reach Moho failed

drilling attempts to the Moho Russia- 1989- 12km 7 miles $100 million 190° C US- 1988 3.5 km

Drilling program April 2005- drilled 1416 meters Gabbro rocks Near Mid-Atlantic Ridge $1.5 billion budget

Lithosphere Rigid- crust + upper mantle Makes up Earth’s plates

Asthenosphere Solid rocks that flow Plates “float” on asthenosphere

MANTLE What we know? Solid that flows (plasticity) magma Composed of iron, magnesium (olivine) Has convection currents

Mantle

MANTLE How do we know it? S waves travel through mantle Volcanoes give us a “peek”

OUTER CORE What we know? Liquid iron How we know it? S-waves do not travel through outer core Magnetic field

Seismic waves P waves S waves Travel through liquids and solids Travel slower thru liquids than solids S waves Do NOT travel through LIQUIDS

INNER CORE What we know? Solid iron How we know it? P-waves speed up Study meteorites
