What if the Earth was five times smaller?

If the Earth were 5 times smaller, which would be the consequences? First of all, we have to consider that the distance between us and the center of the planet will be minor. So, it would be easier to jump in this planet. We would need less energy to reach the potential barrier, and then to scape of the planet. We can conclude that because of the potential energy formula (E=mg). This is caused because of the Earth gravity force to us would decrease.

We have also to think about the surface of the Earth. With the knowledge that there are 3/4 of the surface composed by water and 1/4 of land where we can located the continents, would they fit in? We think that if we reduce 5 times the radio of the Earth the continents would be together and it will be Pangea again. But, it would also happen that the continents crash. Then, it could cause a superposition among the tectonic plaques.
