This phenomenon has to do with melting temperature and pressure. The more pressure a substance is under, the higher its melting point becomes. Both the liquid outer core and the solid inner core are made of an iron alloy, which means that chemically their melting points are the same. However, the outer core is under less pressure simply because it is under less material. The outer core supports the weight of the crust and mantle, while the inner core must also bear the weight of the outer core. The additional mass of the outer core creates enough pressure on the inner core to raise the melting temperature of the iron alloy above the temperature at the center of the earth, causing it to solidify.
So in short, the inner core is solid because it is under more pressure than the outer core.
Hope this helps
The core of the Earth's moon is now solid.
Earth's core is divided into two parts: a solid inner core and a liquid outer core.
Not only is the inner core of the moon solid, but the moon is completely solid all the way through.
The moon is a solid.
The surface of the Moon IS solid.

Titan is a solid. The moon itself is primarily composed of water ice and rocky material.
it is made of solid rock
Moon buggies move around the moon using their huge wheels that have to be solid and able to move around uneven grounds. ( the moon!)

yes
The Earth is solid except for the water, the Moon is solid, but scientists have found frozen rivers...
Yes
No. The planet Pluto is a solid dwarf planet. The moon Charon is a solid moon.
Mostly the Moon's solid mantle comprises olivene and pyroxenes.
It's a solid
No. There is some dust on the moon's surface, but the moon is mostly solid rock.
Titan is a solid. The moon itself is primarily composed of water ice and rocky material.
The moon has a solid (terrestrial) surface.
No, the inside of the moon is solid and cold.
The moon is completely solid, so there is no crust on the moon.
it is made of solid rock
The Moon has a solid core, and therefore has no magnetic field or poles.
