Seismic observations provide strong evidence that Earth's inner core is anisotropic, with
larger velocity in the polar than in the equatorial direction. The top 60–80 km of the inner …

The days when the Earth's inner core (IC) was viewed as a homogeneous solid sphere
surrounded by the liquid outer core (OC) are now behind us. Due to a limited number of data …

Abstract Tides and Earth‐Moon system evolution are coupled over geological time. Tidal
energy dissipation on Earth slows rotation rate, increases obliquity, lunar orbit semi‐major …

The computation of the Love numbers (LNs) for a spherically symmetric self-gravitating
viscoelastic Earth is a classical problem in global geodynamics. Here we revisit the problem …

Geodynamical models and seismic observations suggest that the Earth's solid inner core
rotates at a different rate than the mantle. However, discrepancies exist in rotation rate …

This article commences by surveying the basic dynamics of Earth's core and their impact on
various mechanisms of core-mantle coupling. The physics governing core convection and …

Earth's solid inner core grows through solidification of material from the fluid outer core onto
its surface at rates of about 1 mm per year, freezing in core properties over time and …

Life was limited for most of Earth's history, remaining at a primitive stage and mostly marine
until about 0.55 Ga. In the Paleozoic, life eventually exploded and colonized the continental …

The inner core, extending to 1,221 km above the Earth's center at pressures between 329
and 364 GPa, is primarily composed of solid iron. Its rheological properties influence both …

Abstract Changes in the Earth's rotation are deeply connected to fluid dynamical processes
in the outer core. This connection can be explored by studying the associated Earth …
