1. Differences Between Prime Meridian And Equator. 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. Parts on the equator have a constant 12 hours of day light all year round. The time calculated on the basis of the distance between prime meridian and the longitude of a certain place in known as local time. As far as I know Prime meridian and Greenwich meridian is same. The equator and prime meridian are both invisible lines that circle the Earth and help us in navigation. Local time implies the time of a particular country, as regards the meridian running through it. Change is most visible near UK. Equator seperates the northern and southern 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 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. 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. It is the point from where the latitude is calculated. Find the time of this place. In our daily life, the longitude for any place can find out by using the time difference between UTC and that place. 1. 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. It changes due to shift in longitude.It refers to a time of particular place or country. The prime meridian is an imaginary line dividing the earth into East and West Hemispheres, at 0° longitude. Join now. 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 basically divides the Earth into two hemispheres, i.e. The Prime Meridian is the universally decided zero longitude, an imaginary north/south line which bisects the world into two and begins the universal day. Standard Meridian and Standard Time. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. We have hot summers and cold winters because of the tilt of the earth’s axis. 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. Ask your question. The equator is the imaginary circle that draws a line between the Northern hemisphere and Southern hemisphere. The time difference can also be thus calculated. This portal is designed to support Students and Teachers of Central Board of Secondary Education. For example, despite being on different longitudinal positions, New York and Pittsburgh have a similar standard time. Local time implies the time of a particular country, as regards the meridian running through it. It divides Earth into Eastern and Western Hemispheres. 2. Indian Standard Time (IST) is the time zone observed throughout India. A prime meridian is the meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. 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. 2. Here we’ll break down the significant differences between local time and standard time.

Northern hemisphere and Southern hemisphere, Eastern hemisphere and Western hemisphere, Image Courtesy: primaryhomeworkhelp.co.uk. standard time is the time that doesn't differ and it is fixed for a particular country. It divides the earth into eastern and western hemisphere. This site is using cookies under cookie policy. Local time depends on the movements of the sun. Though invisible, the equator (0 degrees latitude) is a very real location that divides the world into the Northern and Southern hemispheres.
