Tides are daily movements of ocean water that change the level of the ocean's surface.The tides are caused by the exertion of gravitational forces by the moon and sun, and the rotation of the Earth. The relationship between the phases of the moon and the tides was first discovered more than 2,000 years ago by Pytheas, a Greek explorer. However, Pytheas could not explain the reasons behind the relationship. It was not until Sir Isaac Newton published his theories on gravitational pull in 1687 that the relationship between the moon and tides were fully understood. Gravitational forces from both the sun and moon continuously pull on the Earth.
Life has altered the atmosphere by releasing high levels of carbon dioxide along with other chemicals which has been slowly thinning the atmosphere over the years, 3. Why is the rotation of Venus different from that of Earth? All the planets in the solar systems rotate counter clockwise around the sun except Venus. Venus rotates clockwise or retrograde around the sun. Venus also has the slowest rotation out of all the planets rotating around the sun every 243 Earth days.
The further away from the equator a location resides, the less sunlight that this location receives. Latitude is the main factor affecting global climate - the further you go from the equator, the cooler it gets (all other factors remaining constant). This is because the earth in curved which means that the sun's energy is more concentrated at the equator. The thinner atmosphere at the equator also means that the earth gets hotter here. A slight difference in latitude causes a great temperature difference.
The lunar phases vary cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon and Sun. One half of the lunar surface is always illuminated by the Sun (except during lunar eclipses), and hence is bright, but the portion of the illuminated hemisphere that is visible to an observer can vary from 100% (full moon) to 0% (new moon). The boundary between the illuminated and unilluminated hemispheres is called the terminator. Lunar phases are the result of looking at the illuminated half of the Moon from different viewing geometries; they are not caused by shadows of the Earth on the Moon that occur during a lunar eclipse. The Moon exhibits different phases as the relative geometry of the Sun, Earth and Moon changes, appearing as a full moon when the Sun and Moon are on opposite sides of the Earth, and as a new moon (also named dark moon, as it is
The synodic month “begins” at new moon. Because the Moon is in the same part of the sky as the Sun, the illuminated half of the Moon is not facing us and is not visible. During new moon, the Moon rises and sets at the same time as the Sun, and is therefore in the sky during the day. There is then a progression through the growing crescent phase until we see the right half illuminated; this is known as a first quarter moon. After the first quarter phase, there is another progression, this time through the waxing gibbous phases.
Although there are other factors like cloud cover and wind, I still believe that Singapore’s temperature is still affected by its latitude to a large extent as it is the underlying factor. One of the factors which would affect Singapore’s temperature would be its latitude. Due to the angle of incidence being very little with only 1.3˚ north of the Equator, Singapore is very close to the equator. At the Equator, the incoming solar radiation strikes the Earth at a right angle. Hence the heat from the Sun is concentrated and more intense, and is spread over a small area.
Astrology vs. Astronomy It is said that all planets are created from star bits, and therefore so are we. If the Earth had not been created the way it was, then we wouldn’t have been created either. In that way we are connected to the stars and the entire universe in more ways than we can probably conceive. Other connections to the heavens and the stars are the Zodiac. The Zodiac signs and constellations corresponding to them were first used as a marker to recognize the rotation and location of the Earth and for astrologers to point telescopes and create star charts.
At the poles, the rays hit the surface more obliquely resulting in a diminished angle of incidence. The energy is distributed over a greater area leading to less intense energy per unit area. Latitude also indirectly affects the thickness of atmosphere that insolation form the sun has to pass through by
An illustration of Northern Winter Solstice: Similarly, at the time of northern summer solstice, the tilt of the Earth (the globe) is also 23.5° to the terminator but with the South Pole in the dark side and the North Pole in the bright side. An illustration of Northern Summer Solstice: At the time of an equinox, the axial tilt is directly in the plane of the terminator, which means that the terminator meets both the North and South Poles; the sun is at the celestial equator. An illustration of the vernal equinox: With respect to the Northern Hemisphere, vernal equinox is the equinox in transition from the winter solstice to the summer solstice and happens between 20-22
The Effects of the sun on the weather The sun: the closest star to Earth in our solar system. We have always known that the sun affects our climate because of it heating up our ozone layer, changing the temperature of our air causing the different seasons. Now scientists are suggesting that the sun also partially controls our weather patterns as well. This makes sense, however, it is a relatively new idea due to the lack of equipment and technology to study the sun up until the mid 19th century. So whether their claims hold any ground is yet to be proven as a fact.
