A A Chain of Miracles

Many independent factors, such as the Earth’s distance from the Sun, its
speed of rotation around its own axis, its angle of tilt, and surface features
all let the planet be warmed in a manner suited to life, and for heat to be
spread across the planet in a balanced way.

small in comparison to Mercury’s, where a single day is longer
than one year. In other words, one rotation of Mercury around
its axis takes longer than one rotation around the Sun.

Temperature can fluctuate by as much as 1,000 C (1,832 F) be-
tween Mercurial day and night.
The Earth’s shape, too, has been created to aid the heat dis-

tribution. The temperature difference between the poles and the

o
equator is approximately 100 C (212 F). If such a difference
were to occur on a smooth sphere, storms at speeds of up to
1,000 km/h (621 miles/hour) would wreak havoc across the
Earth. However, the world has been provided with obstacles
