Hello Friends ,
Today we are going to tell you LATITUDE AND LONGITUDE – so friends read and share it if you like this post more and more share it .LATITUDE AND LONGITUDE -(Date time)
LATITUDE AND LONGITUDE -(Date time)
LATITUDE AND LONGITUDE –
(Date time)
1. Lines of latitude are imaginary lines that run completely around the globe-full circles. Latitude is the angular distance of a point on the Earth’s surface, measured in degrees from the centre of the Earth.
2. The Equator represents 0°. The Equator divides the world into two halves or hemispheres : the Northern Hemisphere and the Southern Hemisphere. All places that are north of the Equator are said to have north latitude. All places south of the Equator are said have south latitude.
3. All lines of latitude are parallel to the Equator and are, therefore, called parallels.
4. Lines of longitude are imaginary lines that extend from the North Pole to the South Pole. Longitude is an angular distance, measured in degrees along the Equator east or west of the Prime Meridan. They are also called meridians. They are not parallel. All the lines meet at the North Pole and the South Pole. 180° longitude divides the world (a circle with 360°) into two equal parts : The Eastern Hemisphere and the Western Hemisphere.
Latitude and Altitude Help Determine Climate : –
There are several things that determine the climate of places on Earth. One is the distance of a place from the Equator. In general, the closer a place is to the Equator, the warmer it will be all the year around. This is because the Sun’s rays strike the Earth more directly near the Equator, and less directly as the North and South Poles are approached.
Five special lines of latitude
Equator at 0°, the Tropic of Cancer at N, the Tropic of Capricorn at S, the Arctic Circle at N, and the Antarctice Circle at S.
At the Arctic Circle there is one day of the year that the Sun does not rise or set. As one gets closer to the north pole, the number of days the Sun does not rise or set increases. This is because the Northern Hemisphere is inclined toward the Sun for approximately six months (June 22- December 21). The other six months of the year the Sun is not seen because the Northern Hemisphere is inclined away from the Sun (December 22-June 21). The reverse of this process takes place in the Southern Hemisphere and south of the Antarctic Circle.
Places that are on the same meridian have the same local (Sun) time. The Earth rotates 15° each hour in a west-to-east (counter-clockwise) direction. Thus, in 24 hours the Earth rotates 360° (36015°=24 hrs). Therefore, as one moves east from the Prime Meridian (0°) the time increases by 4 minutes for every longitude (24 hrs. 360°). Similarly, if one moves west from the Prime Meridian the time decreases by 4 minutes with every longitude.
The International Date Line : –
Greenwich Mean Time (GMT) is considered to be the world standard time, which represents the Prime Meridian. However, to avoid difficulty every country maintains their own standard time based on the central meridian of their own country. The Indian Government has accepted the meridian of 82.5°E for the Indian Standard Time (IST), which is 5 hrs. 30 minutes ahead of GMT. For larger countries, more than one time zones are adopted.
To prevent “date” confusion, the international Date Line was established. As a traveler on ship or plane crosses this line, he changes the date. Thus the traveller crossing the International Date Line from west the east gains a day and from east to west loses a day.
The International Date Line is located entirely in the ocean. No body of land is divided by the date line. For the most part it follows the 180th meridian. But in the mid-Pacific it curves from the normal 180° meridian at the Bering Strait, Fiji, Tonga and other islands to prevent confusion of day and date in some of the island groups that are cut through by meridian.
