Greenhouse effect. (good)

Formation of Earth and Moon Earth’s atmosphere is
partly due to Earth’s mass and gravitational force.
The Earth also produces new gases to replenish what is lost.
Moon is believed a piece of the Earth that broke off at early formation. Remained in Earth’s gravitational field.
Moon has no atmosphere because of its mass.
