Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south.

Cartographers and geographers trace horizontal and vertical lines called latitudes and longitudes across Earth's surface to locate points on the globe. The Earth is, almost, but not quite, a sphere that rotates around its axis. Scientists call this shape a spheroid or ellipsoid. If we draw a line passing through the center of the Earth along its rotational axis, the line would pass through the North and the South Pole. The Equator is an imaginary line perpendicular to this axis.

Most locations on the Equator experience consistently high temperatures throughout the year. They also experience at least 12 hours of daylight every day during the year.

On the Equinoxes — September and March — the Sun is directly overhead the Equator, resulting in almost exactly 12 hour days and 12 hour nights. Often called parallels or circles of latitude , latitudes are imaginary circles parallel to the Equator.

They are named after the angle created by a line connecting the latitude and the center of the Earth, and the line connecting the Equator and the center of the Earth. Latitudes specify the north-south position of a location on the globe. Locations in the Northern Hemisphere are identified by northern latitudes and are assigned a suffix of N for north. Southern Hemisphere locations, on the other hand, are on southern latitudes and are assigned a suffix of S for south.

Find celestial objects in the sky. In addition to the Equator, there are four other major latitudes that are usually found on maps and globes. The positions of these latitudes are determined by the Earth's axial tilt. All locations falling north of this latitude are said to be in the Arctic Circle. Any locations falling south of this latitude are said to be in the Antarctic Circle. Places in both the Arctic and Antarctic circles experience the Midnight Sun and polar night.

It marks the northern-most position on the Earth, where the Sun is directly overhead at least once a year. It is the southern-most position on the globe, where the Sun is directly overhead during the December Solstice. Sometimes, latitudes north of the Equator are denoted by a positive sign.

Latitudes south of the Equator are given negative values. This eliminates the need to add whether the specified latitude is north or south of the Equator. Longitudes are geographical positioning markers that run from the geographical North Pole to the geographical South Pole, intersecting the Equator.

They meet at both Poles, and specify the east-west position of a location. Longitudes are, therefore, imaginary circles that intersect the North and South Poles and the Equator. Half of a longitudinal circle is known as a Meridian. Meridians are perpendicular to every latitude. Unlike, latitudes, there is no obvious central longitude. However, in order to measure the position of a location based on the longitude, cartographers and geographers over the course of history have designated different locations as the main longitudinal reference point.

Today, the meridian line through Greenwich, England, is considered as the reference point for longitudes. This line is also known as the Prime Meridian. All the other longitudes are measured and named after the angle they make with respect to the center of the Earth from the intersection of the Meridian and the Equator. Since a sphere has degrees, the Earth is divided into longitudes. Modern timekeeping systems use longitudes as references to keep time.

Time zones are defined by the Prime Meridian and the longitudes. One easy way to remember the orientation of latitudes and longitudes is long itudes are long , and lat itudes are lateral.

A Great Circle is any circle that is formed by a plane that passes through the center of the Earth. The Equator and the circles created by the meridians form Great Circles. The shortest line between two points on the Earth's surface is always the arc of a Great Circle. Because of this, Great Circles are important for the study of migration and other human interactions and activities, including shipping and airline routes. Topics: Time Zone , Earth , Geography.

Present the three commonly used ways of displaying latitudes and longitudes: degree, minutes, seconds; degree decimal minutes; decimal degrees. The grid lines are called latitude and longitude. They are measured in degrees.. Project the Lines of Latitude diagram and invite a volunteer to point out the Equator. Find interesting answers to your puzzling Latitude And Longitude questions.

## Latitude and longitude

Latitude is a measurement on a globe or map of location north or south of the Equator. Technically, there are different kinds of latitude— geocentric, astronomical, and geographic or geodetic —but there are only minor differences between them. In most common references, geocentric latitude is implied. As aids to indicate different latitudinal positions on maps or globes, equidistant circles are plotted and drawn parallel to the Equator and each other; they are known as parallels , or parallels of latitude. In contrast, geographic latitude, which is the kind used in mapping, is calculated using a slightly different process.

Meridians lines running from pole to pole connect points with the same longitude. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the earth's rotation, there is a close connection between longitude and time. Comparing local time to an absolute measure of time allows longitude to be determined. Depending on the era, the absolute time might be obtained from a celestial event visible from both locations, such as a lunar eclipse, or from a time signal transmitted by telegraph or wireless.

You can teach this to your students when they work on latitude and longitude worksheets. Basics of navigation with important vocabulary for students to know like navigation, latitude, longitude, equator, prime meridian, cardinal directions, compass and GPS or Global Positioning System are discussed.

С годами она приобрела гибкость и грацию. У нее была высокая стройная фигура с пышной грудью и по-юношески плоским животом. Дэвид шутил, что она может стать первой моделью для рекламы купальников, имеющей докторскую степень по прикладной математике и теории чисел. Через несколько месяцев оба начали подозревать, что обрели нечто такое, что может продлиться всю жизнь. Они были вместе уже два года, когда Дэвид вдруг сделал ей предложение.

Темнота стала рассеиваться, сменяясь туманными сумерками. Стены туннеля начали обретать форму. И сразу же из-за поворота выехала миниатюрная машина, ослепившая ее фарами.
