Answer 3

Thckest layer moves in circular motions called convection currents around 1000 degrees near the crust and 3700 degrees near the outer core made of semi molten rock liquid rock solid rock that can flow

Question 4

Properties of the outer core

Answer 4

Semi liquid iron tempreture between 3700-5000 degrees around 2300km thick iron magnetic so the earth magnetic field come from here protecting use from harmful solar flares

Question 5

Properties of the inner core

Answer 5

Around 1250km thick hottest part of the earth reaching temps over 5000 degrees made of iron and nickel under lots of presure 4x as dense as minerals in the crust the rock is soild in the inner core becuase of the presure
