From Zero Degrees Latitude To The South Pole

From Zero Degrees Latitude To The South Pole – If you look at a map of the world or the world, you might see east-west and north-south lines.

East-west lines are called lines of latitude. North-south lines are known as lines of longitude.

While lines of latitude run east-west across the map, latitude indicates the location of a place on the ground in a north-south direction.

Latitude, Longitude, And Time Zones

Latitudes start at 0 degrees at the equator and end at 90 degrees at the north and south poles (up to 180 degrees latitude). Therefore, the higher the latitude value, the closer it is to the North or South Pole.

Anything north of the equator is known as the northern hemisphere, and anything south of the equator is known as the southern hemisphere.

Latitudes are said to be parallel and join each other at 180 degrees latitude. The distance between each point of latitude is 69 miles (110 km).

For example, the 49th parallel marked a portion of the border between Canada and the United States that was negotiated between the United States and Britain as part of the 1818 treaty:

Selenographic Coordinate System

It is accepted that a line extending from the extreme northwest point of Forest Lake, through the 49th parallel of north latitude, or if that point is not the 49th parallel of north latitude, then a line extending from that which points north or south, until that line crosses the parallel of latitude north, and from the extremity of that point west with that parallel line the line of demarcation between the territories of Britain. The Dominion and Territories of America, and this line shall be the southern boundary of the said territory of His Majesty’s Great Britain, and the northern boundary of the American territories from the Lake of the Woods to the Stony Mountains.

The five main parallels of latitude from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and Antarctic Circle.

Depending on whether the map is facing north or south, a horizontal line will appear.

The equator divides the earth into the northern hemisphere and the southern hemisphere shows the 0 degree point of latitude. Latitude refers to the angular distance north or south of the equator.

The equator marks the points on earth that are equidistant from the north and south poles. The equator is the only line of latitude that is a great circle, the other latitudes are small circles.

Here’s an interesting fact: the first definition of the meter was in 1793: one ten-millionth (10-7) of the distance between the equator and the North Pole in the great circle.

The current meter definition is: the distance light travels in 1/299, 792, 458 seconds in a vacuum.

The Tropic of Cancer marks where the sun reaches its zenith at that latitude. The exact latitude is not a fixed point, the latest measurement for 2014 is 23° 26′ 14.675″ (23°26′16″).

The summer solstice, which occurs on June 20 or 21 each year, marks the day the sun rises vertically above this parallel.

The northernmost latitude where we can see the sun just above noon is the Tropic of Cancer, which is 23.5 degrees north. Map: Caitlin Dempsey.

Each year the Tropic of Capricorn moves the parallel of latitude, which is 23° 26′ 14.440″.

The winter solstice, which occurs on December 21 or 22 each year, marks the day the sun rises vertically above this line.

The southernmost latitude at which the sun is visible at noon is the Tropic of Capricorn, which is about 23.5 degrees south. Map: Caitlin Dempsey.

Horse latitudes are about 30 degrees north and south of the equator. Equatorial latitudes indicate areas within the continent where winds blow either poleward (known as westerlies) or equatorward (known as trade winds).

Longitude is a line running north-south, indicating the east-west position of a point. Therefore, latitude is the angular distance east or west of the prime meridian.

Lines of longitude run from pole to pole, crossing the equator at right angles. All lines of longitude are the same length. Each line of longitude is half of a great circle.

Longitude is 360 degrees (+180° east and −180° west). The 0 degree line is known as the prime meridian and divides the world into the eastern and western hemispheres.

Distances west of the prime meridian are indicated by – before the year (negative year) and distances east of the prime meridian are positive year (-180 degrees west longitude and 180 degrees east longitude).

The distance between longitudes decreases as we move away from the equator. As you move poleward, the distance between each meridian line decreases until it meets the north and south poles.

The distance between longitudes at the equator is equal to latitude, about 69 miles. At 45 degrees north or south, the distance between them is 49 miles (79 km).

The distance between the longitudes reaches zero at the poles and the vertical lines meet at this point.

Longitudinal lines meet poles whose distance between them is 0. Longitudinal lines. Map: Caitlin Dempsey.

The longitude at which the point is zero is known as the prime meridian. It passes through the Royal Observatory in Greenwich, England, called the Greenwich Meridian, and divides the Earth into two equal halves, called East and West.

A base point is a line that runs north to south at 0° longitude (0 degrees). Map: Caitlin Dempsey.

The line on Earth that changes from one calendar day to the next is called the International Date Line (IDL) and it crosses the Pacific Ocean.

It is usually 180 degrees from the prime meridian, but the line passes through some lands and islands, so that adjacent parts of lands and countries are not divided into two separate days.

There are 23 one-hour episodes and two 30-minute episodes, dividing the world into different time zones. Going east to west along Earth’s Sun Line moves the calendar forward one day.

A double number called a coordinate is used to provide a geographic location using latitude and longitude.

To determine the location of the tallest building in the United States using latitude and longitude: 38° 53′ 35″ N, 77° 00′ 32″ W.

Point movements, which change the minutes and seconds of coordinates, are another way of writing coordinates. When plotting the cardinal directions (N, S, Z, Z, Z) or dots, points west of the prime meridian and south of the equator are in front of the negative sign.

The US Capitol is located in Washington DC, in the northern and western hemispheres. Image: NPS, public domain. We can make the Earth a spherical object, and since we are working with a 3D shape, the shape should be different from the x and y axes. Although adding a z-axis would make sense for navigation, we might be on the surface of this planet when using a coordinate system, meridians and parallels, see the images below.

All these lines form a grid that allows us to describe an area in latitudes   N ↑ ↓ S and longitudes   W ← → E  .

But the East-West divide is the source of political problems. Greenwich (England) won, leaving the Netherlands, for example, in the Eastern Hemisphere and Ireland in the Western Hemisphere.

It takes the earth 24 hours to make a 360° rotation. Therefore, every hour we change by 15° of longitude. The two world maps below show the grid and meridians at 30°:2 hour intervals.

At 12:00 UTC (Universal Standard Time) – anywhere in the world – it is 12:00 local time in Greenwich and 24:00 on the other side of the world: 180° W or 180° W: near the world of the solar line . Crossing this meridian not only changes time, but also the sun.

The North Pole is 90° N, the South Pole is 90° S. The meridians subtending this angle are either 180° W or E.

Latitude And Longitude

Meridians intersect at the poles and parallels are parallel to each other and never meet. All meridians and the equator, which is the longest parallel, form great circles, the other parallels are called small circles. The Great Circle divides the Earth into two right halves, see glossary below.

If the earth had a perfect circle (about 40,000 km in circumference), all would be well.
