Answers
latitude :
an angular distance of a place north or south
Answer:
Latitude- the angular distance north or south from a planet's equator, measured along the meridian of that particular point is known as latitude(or) an imaginary line around a planet running parallel to the planet's equator is known as latitude.
Longitude- the angular distance measured west or east of the prime meridian is known as longitude(or) Any imaginary line perpendicular to the equator and part of a great circle passing through the North Pole and South Pole is known as longitude.
Meridian- a circle of constant longitude passing through a given place on the earth's surface and the terrestrial poles is known as the meridian.
Prime Meridian- a planet's meridian adopted as the zero of longitude is known as the prime meridian.
Local Time- time at a particular place as measured from the sun's transit over the meridian at that place, defined as noon is known as the local time of the place.
Indian Standard Time- Indian Standard Time (IST) is the time zone observed throughout India, with a time offset of UTC+05:30.
Greenwich Mean Time- Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London, reckoned from midnight.
International Date Time- The International Date Line (IDL) is an imaginary line of demarcation on the surface of Earth that runs from the North Pole to the South Pole and demarcates the change of one calendar day to the next.
Great Circle- A circle on the surface of a sphere which lies in a plane passing through the sphere's centre is known as the great circle.
Small Circle- a circle on the surface of a sphere whose plane does not pass through the sphere's centre is known as the small circle.
Grid- A grid system is a set of measurements a graphic designer can use to align and size objects within the given format.
