Learn facts about Earth's core. Discover what the center of the earth is made of and examine the importance of Earth's core's temperature and magnetic field. Updated: 11/21/2023 Table of Contents What is the Core of the Earth? What is the Center of the Earth Made Of? Earth's ...
The Earth's core is an alloy of iron and a light element such as sulphur, oxygen or silicon. Starting with static equations of state of Fe, Fe3Si, Fe7S, Fe3S and FeS, calculated from density functional theory, we can estimate the core composition as a function of thermal pressure. We...
This paper attempts to estimate the temperature of the deep interior of the early Earth. The initial temperature cannot be too high or too low in order to realize the present-day thermal state, such as the surface heat flow and the inner core size. Two constraints have been placed: (1) ...

The associated five minute segments, each covering ≈2000 × 1350 km of the Earth’s surface and referred to as granules, have ≈1 km spatial resolution and span the entire ocean, clouds permitting, twice daily. For this study, we examined all nighttime granules from 2003–2019. The SST ...
