Does the Earth and moon have large molten core or only 1 of them does?
I think the Earth only has large molten core
You are correct! The Earth indeed has a large molten core, while the Moon does not. To understand this, let's dive into some scientific details.
The Earth's core is composed of two parts: the outer core and the inner core. The outer core is primarily molten, made up of liquid iron and nickel. It surrounds the solid inner core, which is believed to be mostly made of iron.
The molten core of the Earth plays a crucial role in generating a magnetic field that surrounds our planet. This magnetic field protects us from harmful solar radiation and also helps to maintain our atmosphere.
On the other hand, the Moon's core is much smaller and has significantly cooled down over billions of years. It is now mostly solid, with only a small amount of residual heat left. This is why the Moon does not have a molten core like the Earth.
Scientists believe that the Moon's core originally had a molten state when it was formed, but due to its smaller size and lack of significant internal heat, it solidified relatively quickly.
In summary, the Earth has a large molten core consisting of an outer and inner core, whereas the Moon's core is mostly solid and significantly smaller in comparison.
