Mercury Surface
The Mariner 10 is how

observations.
Mercury surface is
similar to the Moon’s
surface it is covered
with craters ad plains
The plains of Mercury’s
surface are smooth
and relatively crater free
Its thought that the plains were formed
from lava flows that covered cratered
terrain, much like the Maria on the
Moon
The surface gravity of Mercury is much
greater than that of the Moon.
Mercury has a planet wide system of
cliffs called scarps scientists
hypothesize that the scarps developed
as Mercury's crust shrank and fractured
early in the plant’s
Interior
Scientist have no data
with which to analyze
the interior of Mercury.
The high density of the
planet suggests that
Mercury has an
extensive nickel-iron
