- Since the earth's axis is tilted 23 ½ degrees, then on this particular day, the sun's rays are striking the earth directly at a latitude approximately 23 ½ degrees north of the equator (that is, the sun's rays are coming in at an angle of 90 degrees here; this is the subsolar point).

The Tilting of the Earth: Shaping Our Seasons and Climates As the Earth continues along its path around the sun, its angle constantly shifts the North Pole away from the sun and the South Pole toward the sun. The sun’s energy is more concentrated on the Northern Hemisphere where its rays hit the Earth more directly and are thus more intense.

The Reasons for the Seasons Earth's orbit around the Sun is only slightly elliptical. The difference between its closest point to the Sun and its most distant is little more than 3 percent. That isn't enough to cause huge temperature swings. It translates to a difference of a few degrees Celsius on average.

- Well that depends on where you live and if you call July summer . Earth is at the far end (aphelion) of its eliptical orbit in the northern hemisphere's summer (~July 4), and at its closest (perihelion) during winter ~(January 4).It is not Earth, but your location on Earth that gets more direct rays of the sun in summer than in winter.This has to do with your latitude location on earth (e.g., 45° north) and the axial tilt of the earth.he sun, on the other hand, is usually 92,955,902 miles (149,598,023 kilometers) away. So, on … average, the moon is 388 times closer to the earth than the sun is. On average, light takes about 8 minutes, 18 seconds to get from the sun to the earth; it goes from the moon to the earth (or vice versa) in 1.3 seconds.

General Astronomy/Print version The latitude of the Earth's Equator is by definition 0° (zero degrees). The Equator is one of the five notable circles of latitude on Earth, with the others being the two Polar Circles: the Arctic Circle and the Antarctic Circle, and the two Tropical Circles: the Tropic of Cancer and the Tropic of Capricorn.t the equinoxes, the Earth's axis is not tilted toward the sun, instead it is perpendicular to the sun meaning that the day is about 12 hours long, as is the night, across the whole of the Earth. Near the Equator there is little distinction between summer, winter, autumn, or spring.

What is the Arctic? The Arctic Circle marks the latitude above which the sun does not set on the summer solstice, and does not rise on the winter solstice. At the North Pole, the sun rises once each year and sets once each year: there are six months of continuous daylight and six months of continuous night.

Summer Solstice 2017: Facts to Know About the Longest Day of the Year At solar noon Monday, the sun will be directly over the Tropic of Cancer, a line of latitude located at 23.5 degrees north of the equator. During the summer, the Northern Hemisphere receives the most direct sunlight because it is tilted toward the sun.

- Location (latitude) on the Earth where the Sun on a particular day is directly overhead (90° from horizon) at solar noon. This location is somewhere between 23.5° North and 23.5° South depending on the time of the year. Citation: Pidwirny, M. (2006). Glossary of Terms: D.

- Day length varies with the time of year and the latitude at which you are situated. Because of the earth's tilt, areas above the Arctic Circle receive 24 hours of sunlight each summer, but 24 hours of darkness each winter.

- On the equator, the length of day and night are equal every day of the year-day is always twelve hours long and night is always twelve hours long. The Tropic of Cancer and the Tropic of Capricorn each lie at 23.5 degrees latitude.

How the Earth Works The Earth's relationship with the sun also creates seasons. The Earth's axis tips a little -- about 23.5 degrees. One hemisphere points toward the sun as the other points away. The hemisphere that points toward the sun is warmer and gets more light -- it's summer there, and in the other hemisphere it's winter.

The Tilting of the Earth: Shaping Our Seasons and Climates The Earth is constantly changing its position with the sun. That’s because the Earth tilts in relation to the sun. That is what creates the differences in the seasons and the annual warming and cooling cycles of the Earth’s Northern and Southern Hemispheres. The Earth is tilted 23.5 degrees on its axis, a straight line through the planet from the North Pole to the South Pole.

(S-1) Sunlight and the Earth How sunlight is created The Sun has no sharply defined surface like that of the Earth, because it is too hot to be anything but gas. Rather, what appears to us as the surface is a layer in the Sun's atmosphere, the photosphere (sphere of light) which emits light (radiates) because ot its high temperature.unlight carries energy, which warms up the Earth and is the driving force behind all our weather and climate. As the ground is heated by sunlight, it begins to radiate, but being too cool to radiate even a dull red, its radiation is in the infra-red range.

- Geometrically the perihelion end of Wormwood’s elliptical orbital plane and the solar ecliptic plane intersect at right angles to form a line from RA: 18 h position on the summer side of Earth’s orbit through the center of the sun to RA: 6 h position on the winter side of Earth’s orbit.

Key concepts At winter solstice (21 December), the sun's rays make an angle of -23° 27' to the equatorial plane. The beam radiation is approximately perpendicular to the Tropic of Capricorn (20°30'S). In the northern hemisphere, the days are at there shortest and the solar altitude at noon has its lowest values.

Energy: The Driver of Climate All objects actually emit radiation if their temperature is greater than absolute zero. Absolute zero is equal to zero Kelvin, which is equal to -273°C or -460°F. Both the sun and Earth's surface behave as blackbodies.

Where Do the Sun and Stars Rise? Each day the rising and setting points change slightly. At the summer solstice, the Sun rises as far to the northeast as it ever does, and sets as far to the northwest. Every day after that, the Sun rises a tiny bit further south. At the fall equinox, the Sun rises due east and sets due west.

- Note how the Sun emits the most radiation in the visible range (with some overlap in the UV and IR) while the Earth emits mostly infrared radiation. The incoming energy from the Sun to Earth is mainly visible sunlight, called the visible portion of the spectrum of electromagnetic radiation.We perceive visible sunlight as colors from violet (short-wave radiation) to red (long-wave radiation).he Spectrum of Electromagnetic Radiation. An idealized spectrum of electromagnetic radiation from the Sun, with a temperature of 6000 °C (~11,000 °F) , and the much cooler Earth, with a surface temperature of 15 °C (~60 °F).

Sun-Earth Relationships: Causes of the Seasons As the Earth rotates each day, and a given point moves from dawn to noon to dusk, the sunlight angle of incidence is high, then low, then high. As you move from pole to equator, the angle of incidence at noon moves toward zero - with the Sun straight overhead.

Geography of the Tropic of Cancer Solar insolation is most at the subsolar point (the point on Earth that is directly beneath the Sun and where the rays hit at 90 degrees to the surface) which migrates annually between the Tropics of Cancer and Capricorn because of the Earth's axial tilt.
