At one point in Earth's history there was an event called the Iron Catastrophe, where iron sank to the interior of the Earth, melting the entire planet as a result of the friction. Minerals and material settled into layers based pretty much on density. As the planet cools from the loss of this residual heat loss, and from the gradual reduction in decay-able radioactive elements, the outer core will eventually solidify and the loss of heat will result in the loss of our magnetosphere and the processes that are behind the rock cycle.

Has the Earth's moon's surface changed in the past three billion years?
Yes, the Earth's moon's surface has changed over the past three billion years due to impacts from asteroids and comets. These impacts have created craters, lava flows, and other geological features that modify the moon's surface over time.
Why does the moon looks like as it did 3 billion years ago?
The Moon has changed over that time. Like Earth, is has been continually bombarded with meteorites and the occasional large meteor. The great crater in Arizona and the meteor that landed in Siberia in 1908 and of course the one that hit near the Yucatan peninsula in Mexico that is believed to have made dinosaurs extinct, being just 3 examples of ones that changed the landscape here. The Moon has also been subject to such events, so it would have changed over time. It may not be radically different, but it is most certainly different.
What best supports the idea that the surface of the moon has changed very little?
The lack of atmosphere on the moon means there is no wind or weather to erode its surface, preserving features for long periods of time. The absence of tectonic activity also means that there are fewer ways for the surface to be reworked or changed over time. In addition, the moon's slow rotation rate means that impacts from meteoroids are the primary source of change on its surface, which are relatively infrequent.
Has the earth always been tilted 23.5 degrees?
No, the tilt of the Earth's axis can vary over long time scales due to gravitational interactions with other celestial bodies like the sun and moon. The current tilt of 23.5 degrees is not constant and has changed over geological time.
