The prime meridian is an imaginary line dividing the earth into East and West Hemispheres, at 0° longitude. They use compasses to determine and label various locations (N. and S. Poles, Prime Meridian, Equator, etc.) seasons. The International date line is a fictive line describing boundaries of time zones (roughly round 180° longitude) with time zone differences of roughly one day. Northern hemisphere and Southern hemisphere, Eastern hemisphere and Western hemisphere, Image Courtesy: primaryhomeworkhelp.co.uk. India’s time is 5½ hours ahead of GMT Calculating Time The longitude of a place is 67.5⁰ E. The time at GMT is 12 noon. 1. This portal is designed to support Students and Teachers of Central Board of Secondary Education. Log in. LSTM = The local standard time meridian, measured in degrees, which runs through the center of each time zone. And the location of a place on the earth can be mentioned in terms of latitudes and longitudes. In our daily life, the longitude for any place can find out by using the time difference between UTC and that place. Lines are used for measuring local time Latitude measures up to 180 0 degrees i.e. It is one of the main imaginary latitude circles , which is actually based on the relationship between the Earth’s axis of rotation. The equator is 0 degrees latitude. It basically divides the Earth into two hemispheres, i.e. In other words, the equator is at 0° latitude. On the contrary, standard time is referred as the official local time of a region ascertained by the distance from the Prime Meridian of the meridian running through the area. places on same longitude , don't have same times when they are different countries. The tilt of the earth means that earth will lean towards the sun, which creates ‘Summer’ or lean away from the sun which creates ‘Winter’, 6 months later. The term Prime Meridian is also written as PM; and it is basically referred to as time. Find an answer to your question differentiate between a) local standard time b) equator and prime meridian 1. Latitudes and Longitudes are imaginary lines used to determine the location of a place on earth. Eastern hemisphere and Western hemisphere. 3. Original time zones 24 hour zones that 1,000 miles apart from the other, each one is an hour before or after the one next to it, helps to differentiate between the differnt times from one point on the Earth to another point. For example, despite being on different longitudinal positions, New York and Pittsburgh have a similar standard time. 1. it changes with the position of sun ad, therefore, may be different in locations within the country.. Standard time – This time is based on the distance of the place from the prime meridian. We have hot summers and cold winters because of the tilt of the earth’s axis. The shape of the earth is ‘Geoid’. Example: The location of New Delhi is 28° N, 77° E. guli sis appie wala b'day❤❤(づ￣ ³￣)づ(♡˙︶˙♡)​, देश में गरीबों की संख्या का पता लगाने के दो भिन्न तरीकों का वर्णन कीजिए​, Class 10 join my quiz topic : resorces and development​, Himalaya ke roop mein upar uthne ke Karan kis samundra ki samapti Hui thi. Equator seperates the northern and southern hemispheres. Every point on the equator is equidistant from the North Pole and the South Pole. The Equator separates the Northern and Southern Hemispheres. The term Prime Meridian is also written as PM; and it is basically referred to as time. Differences Between Prime Meridian And Equator. In short, it can be said that the longitude of a place is the distance from the Prime Meridian. The meridian that tells the Indian Standard Time is 82 ½⁰E. Local time depends on the movements of the sun. Local time – This time is based on the movement of the sun. the standard time at the Prime Meridian. It changes due to shift in longitude.It refers to a time of particular place or country. The sun travels at a rate of 15 degrees per hour (360°/day) across the sky. In other words, the equator is at 0° latitude. Though invisible, the equator (0 degrees latitude) is a very real location that divides the world into the Northern and Southern hemispheres. standard time is the time that doesn't differ and it is fixed for a particular country. You know Nepal lies between 80°E and 88°E longitudes. 1. It does not take into account daylight saving time along with other seasonal factors. LL = The local longitude; positive = East, and negative = West. It divides the earth into eastern and western hemisphere. Log in. . The equator and prime meridian are both invisible lines that circle the Earth and help us in navigation. Standard Meridian and Standard Time. It is latitude 0. This is a worksheet I created to assess my students' understanding of map skills. Comparison between Equator and Prime Meridian: The equator is the imaginary circle, which cuts the spherical Earth exactly in the middle, i.e. ... Main Differences Between Local Time and Standard Time. All meridians intersect at two places; the North Pole and the South Pole. Time = Longitude of a place × 4 … The time difference can also be thus calculated. based on the relationship between the Earth’s axis of rotation. The first parallel is the equator. It runs in the east-west direction. Prime Meridian and Equator: The Prime Meridian is the longitude line (running north and south) that lies at 0 degrees longitude. Great circle: Any line on a sphere that is the intersection between the sphere and a plane passing through the center of the sphere. It divides the earth into northern and southern hemisphere. Note that the equator and prime meridian must be orthogonal, so given the equator the prime meridian can be defined by a single reference point on the sphere that is neither on the equator or at one of the poles. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. On the contrary, standard time is referred as the official local time of a region ascertained by the distance from the Prime Meridian of the meridian running through the area. Greenwich was selected as the prime meridian by a vote of twenty-two in favor, one against (Haiti), and two abstentions (France and Brazil). Prime meridian is defined as a imaginary line which divides earth into two hemispheres estward and westward like equator in short,prime meridian denotes the 0°longitude. The equator is the imaginary circle that draws a line between the Northern hemisphere and Southern hemisphere. Join now. By establishing the prime meridian and 0° longitude in Greenwich, the world was then divided into 24 time zones (since the earth takes 24 hours to revolve on its axis) and thus each time zone was established in every fifteen degrees of longitude, for a total of 360° in a circle. In this article, we will examine the differences between the GMT (Greenwich Mean Time) and IST (Indian Standard Time). LST (local standard time) = Clock time, adjusted for daylight savings time if necessary. Since one uses directions from East and West from a defined prime meridian, then it is called as the two hemispheres. Values range from 0 (the Equator) to 90 (the north and south poles) Values for longitude range from 0 (the Prime Meridian) to 180 degrees This site is using cookies under cookie policy. 90N - 0 - 90S Longitude measures up to 360 degrees Lines decrease in length All lines are of equal length Lines of latitude increase in value from the equator towards the poles Lines of longitude increase in value Eastwards of the Greenwich Meridian Indian Standard Time (IST) is the time zone observed throughout India. The “Prime Meridian” is an old name for the IERS Reference Meridian - Wikipedia, the basis for the measurement of longitude. At the International Meridian Conference, not only was the Prime Meridian's location chosen, but countries also agreed to divide Earth into 24 standard time zones. In between these, spring and autumn will occur. The IRM is the only meridian that may now be described as the prime meridian of the world, as it defines 0 ° longitude by international agreement. In 1884, at an International Conference the prime meridian was officially established as zero degrees longitude. 2. It divides Earth into Eastern and Western Hemispheres. Key Difference: The equator is the imaginary circle that draws a line between the Northern hemisphere and Southern hemisphere.It is the point from where the latitude is calculated. It is the point from where the latitude is calculated. The true prime meridian of the world, as agreed by every nation on the planet in 1984, is the IERS Reference Meridian, which is also known as the International Reference Meridian or IRM. The prime meridian is the vertical line that marks the zero degree longitude measurement on the globe of Earth and intersects the latitude lines that are horizontal. Local time implies the time of a particular country, as regards the meridian running through it. Greenwich is the prime meridian (0°) Parallels don’t intersect. It runs in the north-south direction. Find the time of this place. It is the longest 0 degree longitude. CBSE Guess having millions of pages of educational papers provided by various educational institutions, teachers and educators from India and abroad. *IST is ahead of GMT by 5:30 Hours. in two halves. At latitude 0° (the equator), the day length will be approximately 12 hours. Equator : Prime Meridian: It is the longest 0 degree latitude. In simple terms, equator is the imaginary circle, which cuts the spherical Earth exactly in the middle, i.e. Autumn The North Pole begins to move away from th In fact, the time difference is calculated with the Greenwich Mean Time as the base. The distance of any place from any other place is determined by the longitude of a place. You can specify conditions of storing and accessing cookies in your browser.

The term prime meridian is an imaginary line from north pole to south pole that draws a vertical line, which intersects the latitude lines that are horizontal. The equator is an imaginary line that runs around the middle of the earth dividing it into the Northern and Southern hemispheres. The time calculated on the basis of the distance between prime meridian and the longitude of a certain place in known as local time. The term equator is derived from the Latin phrase, 'circulus aequator diei et noctis', meaning ‘circle equalizing day and night’. 2. The line starts at the north pole, passes across the Royal Observatory in Greenwich, England, and ends at the south pole. Here we’ll break down the significant differences between local time and standard time.
