About the earth
Earth’s tilt of about 23.4 degrees causes the annual cycle of seasons, moderates temperatures, and allows for a wide range of climate zones. “Our planet’s tilt axis seems to be ‘just right,’” says the book Rare Earth—Why Complex Life Is Uncommon in the Universe.3 Also “just right” is the length of day and night, a result of earth’s spin. If the speed of rotation were substantially slower, the days would be longer and the side of the earth facing the sun would bake while the other side would freeze. Conversely, if the earth were to spin much faster, the days would be shorter, perhaps just a few hours long, and earth’s rapid spin would cause relentless gale-force winds and other harmful effects.
About the earth
- Earth’s location in the Milky Way galaxy and the solar system, as well as the planet’s orbit, tilt, rotational speed, and unusual moon
- A magnetic field and an atmosphere that serve as a dual shield
- Natural cycles that replenish and cleanse the planet’s air and water supply
Earth’s magnetic field
The center of the earth is a spinning ball of molten iron, which causes our planet to have a huge and powerful magnetic field that stretches far into space. This shield protects us from the full intensity of cosmic radiation and from potentially deadly forces emanating from the sun. The latter include the solar wind, which is a steady stream of energetic particles; solar flares, which in minutes release as much energy as billions of hydrogen bombs; and explosions in the outer region, or corona, of the sun, which blast billions of tons of matter into space. You can see visible reminders of the protection you receive from the earth’s magnetic field. Solar flares and explosions in the sun’s corona trigger intense auroras, colorful displays of light visible in the upper atmosphere near earth’s magnetic poles.I got this information from- Was Life Created?
