Clarification

Greenhouse effect. (good)

Greenhouse gases like CO2 absorb heat in the atmosphere. (good)

Too much CO2 and we have global warming. (bad)

Ozone Layer (good)

O3 in atmosphere protects us from ultraviolet radiation from the Sun. (good)

Chlorine derived gases deplete ozone. (bad)

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.
