Earth Structure Swag

Jack and Cameron

The Crust• the crust is Earths outermost layer• thinnest layer• thinnest at ocean• thickest at mountains

crust

The Mantle• rocky layer• temperatures from

3,300°F• able to flow• solid

Inner and Outer Core• inner core is solid• outer core is hot liquid• inner core is greater than

5,000°F

Earths Landforms• Formed when Crust is pushed up• Formed when worn down by Earth`s

surface• Sometimes formed underground• Formed naturally

Water• covers almost 75% of Earth• oceans hold about 97% of Earth`s

water• bays, lakes, etc. hold the other 3%

Atmosphere• layering of gases over the

Earth• it includes oxygen• makes life possible• Blocks harmful rays of sun
