Some Examples of Fine-Tuning

• The mass and size of the earth to have a livable atmosphere

• The distance of earth from the sun

• The tilt of the axis of the earth (insures the seasons and livable temperature differences)

• The presence of a single moon (causes the tides which cleanse the shores and aerate the oceans providing oxygen for the plankton, which is the foundation of the food chain)

• The composition of the atmosphere (78% nitrogen, 21% oxygen)

• The nitrogen cycle – lightning (100,000 bolts daily) gets nitrogen out of the air and into the soil for plant food

• The ozone layer – absorbs killer rays from the sun

• The strength of the magnetic field

• The rotation period of the earth (how long a day is)
