Question

14. Consider the planet Mercury with its ancient surface. Can we assume this planet is geologically dead or it there still some activity? If there is activity provide two pieces of evidence supporting the existence of active processes.

Answer 1

given

the planet Mercury with its ancient surface,

this planet is geologically has some activity still today.

the mass m = 3.285 x 10²³ kg

radius is R = 2,439.7 km

gravity g = 3.7 m/sec²

distance form the sun is 57.91 million km

actually planet Mercury is smallest planet among 9 planets,

it is 18 times smaller than the earth.

and has no sub planets, this is near to the sun but it is not that much hot and fastest planet.

so finally,

the planet Mercury is active but it is very smaller than the Earth.
