CROSS-SECTION OF THE EARTH

Today we are going to make individual cross-sections of the Earth's interior from the Inner Core to the Crust.

Each of you is going to cut a piece of paper 656 mm long at the little table.

Inner Core 1,200 km ==> Outer Core 2,300 km ==> Lower Mantle 2,400 km ==> Upper Mantle 600 km ==> Crust 5-70 km

Our Scale is going to be 1:100,000 (1 mm = 1 km)

1) Start at one end and measure 120 mm - draw a line with your pencil here. This is going to represent the Inner Core. We are going to color it light yellow (see page 104).
2) From THIS line measure 230 mm, draw another line. This is going to represent the Outer Core. Yellow/Orange/Red (see page 104)
3) From THIS line measure 240 mm, draw another line. This is going to represent the Lower Mantle. Red andOrange
4) From THIS line measure 60 mm, draw another line. This is going to represent the Upper Mantle. Dark Red You should be 6 mm from the edge of the paper. This is going to represent the Crust. Brown/Green on the bottom (dirt/trees) and Blue on the top (atmosphere)
