Venus is hot while Mars is iron planet.
Mars is a big planet while Venus is a medium planet.
Determine the reason why each planet differs from physical characteristics such as mountains?
Due to tectonic activity.
Due to the shaking of the ground.
Due to volcanic eruptions.
All of the above
Explain why atmosphere is one of the factors that make a planet habitable?
Atmosphere serves as an insulating blanket or protective shield from foreign object.
For meteorological events purposes.
It serves as an oxygen reservoir.
Atmosphere holds us.
