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.
