Much nickel-56 forms in Asymptotic Giant Branch stars and supernovae. However, nickel-56 decays with a half-life of 6 days. In nuclear fusion in stars, He-4 …
WebbThe core-mantle boundary (CMB in Figure 3.9) is apparent as a sudden drop in P-wave velocities, where seismic waves move from solid mantle to liquid outer core. The boundary between the outer core and inner core is marked by a sudden increase in P-wave velocity after 5000 km, where seismic waves move from a liquid back into a solid again. five nights at freddy\u0027s free pokiWebbIt is the movement of the fluid iron in the outer core that creates Earth’s magnetic field (see section 4.2 ).
