Answer: the four terrestrial planets must once have been hot enough to be molten (like a liquid)
Explanation: Terrestrial planets can be defined as any planet of the solar system or any exoplanet which is "Earth-like" in the sense that it is composed primarily of metals and rock, in contrast to a planet which is a gas giant.
Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars.
Scientist believing that the densest, heaviest materials are at the center and not evenly distributed can be due to the fact that they must once have been hot enough to be molten. In this case, density will take place, making the heavier under and the lighter on top.
Hello!
You would want to turn on your headlights. When it is sunrise it could be foggy outside. So for cars in front or behind you to know you are there, you would need to have your lights on. after sunset, it is obvious as to why you need your headlights on. If you don't have them on, nobody can see you which will end in an accident (which will most likely be your fault.)
I hope this helped!
I am, yours most sincerely,
