NASA discovers three things that impact Earth's spin

The video discusses the impact of large glaciers on Earth's surface, explaining how they compress the planet and cause it to bulge. As glaciers melt, the land regains its shape, a process known as glacial rebound, which contributes to Earth's axis wobble. The melting of ice, driven by greenhouse gases, accounts for a significant portion of this wobble. Additionally, mantle convection, involving the movement of molten rock, redistributes Earth's mass and affects its spin.
