Moon's Interior and Geological Features

The video explores the Moon's interior, revealing it has a structure similar to Earth's, with a solid inner core and a fluid outer core. Historical studies and Apollo missions provided initial insights, while recent research using data from various space missions has refined our understanding. The Moon's core is iron-based, and mantle overturn processes explain the distribution of elements on the surface. The findings also shed light on the Moon's past magnetic field, contributing to a deeper understanding of its geological history and the solar system.

What is the composition of the Moon's inner core?

• Solid nickel

• Solid iron

• Liquid nickel

• Liquid iron
