Seasons are caused by the tilt of Earth's axis of rotation at 23.5 degrees offset of the axis from the direction perpendicular to the Earth's orbital plane. The direction of the rotational axis stays nearly fixed in space, even as the Earth revolves around the sun once a year. As a result, when the Earth is at a certain place in its orbit, the Northern hemisphere is tilted towards the sun and experiences summer. Six months later the Northern hemisphere is tilted away from the sun and experiences winter. The seasons are reversed for the Southern hemisphere.
Many factors change due to the tilt of the Earth, whether it is at the normal 23.5 degrees, at 45 degrees or at no tilt at all. The tilt of the Earth has a major effect on the seasons around the world and the amount of daylight that each particular geographic location receives.
If the Earth were not tilted, the days would act like the equinox at all geographic locations. Thus, each area would experience 12 hour days and 12 hour nights. If the earth were tilted at 45 degrees, days in the Northern hemisphere during winter would be shorter as you move towards the pole. If you were in the Southern hemisphere your days would be longer as you moved towards the pole. The Arctic circle and Antarctica would experience total darkness and total light throughout the year., depending on the amount of direct sunlight that those locations receive. During summer solstice when the Earth is tilted at a 45 degree north slope you would have total darkness and total light, this would of coarse be reversed in the Southern hemisphere.
At the equator you would see 12 hours of daylight and 12 hours of darkness at the equinox's. The days would decrease through the winter and then the Spring equinox the days would decrease through summer. The result of this is extreme day changes at the equator. For instance, at summer solstice, our northern tier of states(anywhere north of 45 degrees north latitude) would receive 24 hours of sunlight, the downside to this is that winters would be long, dark and cold.
It takes Mercury 59 Earth Days to rotate around its axis. ... Mercury resembles the Earth's moon. ... Mercury's day equals 3 Earth months. ... Venus is Earth's sister planet. ... This planet tilts 23.5 •X on its axis, causing seasonal changes. ...
Jupiter is 5.2 times farther away from than the Sun than the Earth. ... Jupiter doesn't have seasons because seasons are caused by a tilted axis, and Jupiter's axis is only tilted 3 degrees, which is not enough to cause seasons. It takes Jupiter 9.8 Earth hours to revolve around its axis this is a Jovian day. ... This is a little bit more than 11 times the diameter of the Earth. ... The gravity on Jupiter is only 254% of the gravity on Earth. ...
One of the most predominate issues that is considered in the human mind today is of the question, "Does God exist?" Logically speaking there are rules, or more often called, laws that govern the way we act and think, one of such laws is looked at as the law of excluded middle. In this rule we basi...
The moon is the sister world of earth. ... This is not quite the same as its orbital period around earth. ... For example, if the earth, sun and moon are in line, with the earth being in between the sun and the moon; we would see a full moon. ... The moon is rotating around its axis. ... If it were not rotating on its axis we would see all sides of it in its 27 ½ day cycle, and if it were rotating faster we would also see all sides of it. ...
As the Earth is a living planet, it is constantly undergoing change. ... Additionally, we know that the motion of the Earth, known as the Milankovitch cycles, also affect the Earth's atmosphere. These cycles - the Earth's elliptical orbit, the tilt of the Earth's axis, and the procession of the equinoxes - all have an effect on the Earth in various ways. The Earth's orbit brings the planet closer to the Sun at one point in its 100,000 year trip. ... These increases have enhanced the heat-trapping capabilities of the Earth's atmosphere. ...
The sun heats the earth's air, land, and oceans at different rates, causing ocean currents and winds to exist. ... There are two types of wind turbines: horizontal axis and vertical axis. The horizontal axis turbine looks much like your typical windmill. ... Developers are now focusing on developing a new horizontal axis wind turbine on the principles of Charles Schachle. ... The vertical axis turbine is less efficient than the horizontal axis turbine; however, because of its simplicity it is more economical. ...
Use a Timeline to outline the historical developments of models of the universe from Aristotle to Newton. 330 BC Aristotle described the Earth to be a stationary object or Sphere at the centre of the Universe with the sun, stars and planets moving Around the Earth. This began the concept of a Geocentric Universe Aristotle Stated that: 1) The universe contained the Earth which was surrounded by 55 concentric Spheres each sphere containing a heavenly body 2) The closest Sphere c...
Everyday, the world produces carbon dioxide that is released to the earths atmosphere and which will still be there in hundred years. ... One is called horizontal axis wind turbine and the other one is called vertical axis wind turbine. Horizontal axis wind turbine is the propeller turbines that you often see in the large wind farms that cross the United States. In this paper, I will mainly discuss about vertical axis wind turbines; and this new technology is named Windspire. ... This axis is an input shaft that is connected to a gearbox that drives the output shaft many times faster than the...
The major premises of Copernicus's theory are that the earth rotates daily on its axis and revolves yearly around the sun. He argued, furthermore, that the planets also circle the sun, and that the earth precesses on its axis (wobbles like a top) as it rotates. ... Unfortunately, it was too late, Galileo's health was slowly failing and by 1638 the man who could see beyond the Earth horizon was completely blind. ...
