Slide 2 PREVIEW
Slide 3 Attention Getting Introduction
Slide 4 – Earth’s Crust Intro: solid, semisolid, liquids/ crust, mantle, core, outer core.
Slide 5 – The Crust: size, thickness, comparison of oceanic and continental crusts, and
Slide 6 – Graphics provided from website: NationalGeographicKids.com – Crust Layers and Earth Layers.
Slide 7 – Continental Crust vs. Oceanic Crust Illustration and Description.
Slide 8 – How scientists are able to measure density and thickness of layers of earth: seismic waves.
