5 Could you solve the mystery? North American SouthAmerican

6 Take a look at the continents! South America South America Africa South America It shows how the continents would fit together if you moved the Atlantic Ocean.

7 Outer Core is the liquid layer of the Earths core that lies beneath the mantle and surrounds the inner core. Inner Core The inner core is the solid, dense center of our planet that extends from the bottom of the outer core to the center of the Earth, some6,378 km beneath the surface. Lithosphere15–300km Asthenosphere 250km Mesosphere 2,550 km Outer core 2,200 km Inner core 1,228 km
