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.

What are the large glaciers mentioned in the text that impact Earth's surface?

What is the process referred to when the land regains its original shape after glaciers melt?

How much wobble of the Earth's axis is attributed to glacial rebound each year?

What role do greenhouse gases play in the melting of ice and its effect on Earth's wobble?

In what way does mantle convection affect the planet's spin?
