Influence On The Earth
Because of the axial tilt of the Earth (often known as the obliquity of the ecliptic), the inclination of the Sun's trajectory in the sky (as seen by an observer on Earth's surface) varies over the course of the year. For an observer at a northern latitude, when the northern pole is tilted toward the Sun the day lasts longer and the Sun climbs higher in the sky. This results in warmer average temperatures from the increase in solar radiation reaching the surface. When the northern pole is tilted away from the Sun, the reverse is true and the climate is generally cooler. Above the arctic circle, an extreme case is reached where there is no daylight at all for part of the year. (This is called a polar night.) This variation in the climate (because of the direction of the Earth's axial tilt) results in the seasons.

Famous quotes containing the words influence on the, influence on, influence and/or earth:
“Women stand related to beautiful nature around us, and the enamoured youth mixes their form with moon and stars, with woods and waters, and the pomp of summer. They heal us of awkwardness by their words and looks. We observe their intellectual influence on the most serious student. They refine and clear his mind: teach him to put a pleasing method into what is dry and difficult.”
—Ralph Waldo Emerson (18031882)
“If morality had naturally no influence on human passions and actions, it were in vain to take such pains to inculcate it; and nothing would be more fruitless than that multitude of rules and precepts with which all moralists abound.”
—David Hume (17111776)
“Important as fathers are, their influence on children shouldnt be exaggerated just because they were ignored so long. There is no evidence that there is something especially good about fathers as caretakers. There are no areas where it can be said that fathers must do certain things in order to achieve certain outcomes in children. The same goes for mothers.”
—Michael Lamb (late20th century)
“the plump of my belly, the
hollow of your
groin, as a constellation,
how it leans from earth to
dawn in a gesture of
play....”
—Denise Levertov (b. 1923)
