What are great circle routes What are their importance?
The Great Circle Routes follow the great circles i. e. the perimeters of the earth which cover the shortest distances between any two places in spite of the zigzag routes along the surface of earth. These circles are beneficial for following the shortest distances between any two places and help in saving the time.
What are the two benefits of using the Great Circle route?
1)All meridians of longitude are great circles. Great circle are of importance to navigation and aviation. 2)The shortest route between any two places is along the arc of the great circle which passes through them.
Why are great circles used for air and sea travel routes?
Planes travel along the shortest route in 3-dimensional space. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots fly polar routes saving time and distance.
What is the purpose of great circle sailing?
Great Circle Sailing is used for long ocean passages. For this purpose, the earth is considered a perfect spherical shape; therefore, the shortest distance between two points on its surface is the arc of the great circle containing two points.
What are the advantage and disadvantage of the great circle sailing?
The advantage of a great circle is obvious, the shorter distance. The disadvantages, depending on latitude, could be quite a few. Colder weather, stronger winds, higher seas and perhaps even icebergs.
Why great circles are the shortest route?
(iii) Great Circles are the shortest routes between two places as we can connect any two places on the earth's surface by the curvature line of the great circle. And this curvature is the smallest possible route between those two places, because this curvature directly connects those places or points.
What is the advantage of a great circle?
Great circles are also useful in planning routes. The shortest path between two points on the surface of a sphere is always a segment of a great circle. Plotting great circles comes in very handy for airplane pilots trying to fly the shortest distance between two points.
What is great circle in ship?
Great-circle navigation or orthodromic navigation (related to orthodromic course; from the Greek ορθóς, right angle, and δρóμος, path) is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe.
What is meant by great circle?
A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles.
What is a great circle in geography?
A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles.
Why great circle has a shorter distance than rhumb line in a long ocean passages?
Overall? Over a longer oceanic passage, it makes sense to travel on a Great Circle Circle than the Rhumb Line due to the extra time and energy involved.
What are the main characteristics of the great circle?
The main characteristics of a Great Circle are:
- A Great Circle is the largest circle that can be drawn on the surface of the Earth.
- Many numbers of Great Circles can be drawn on the surface of the Earth.
- All Great Circles divide the Earth into two hemispheres.

What is a great circle route in geography?
great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere's centre and was known by mathematicians before the time of Columbus.
What are the main characteristics of great circle?
The main characteristics of a Great Circle are:
- A Great Circle is the largest circle that can be drawn on the surface of the Earth.
- Many numbers of Great Circles can be drawn on the surface of the Earth.
- All Great Circles divide the Earth into two hemispheres.

What is a characteristic of the Great Circle route?
Arcs of great circles are the shortest route between two points on a sphere. Characteristics: 1. A great circle is a theoretical circle formed by the intersection of the Earth's surface and an imaginary plane that passes through the center of the Earth and divides it into two equal parts.
Why are great circles the shortest path?
(iii) Great Circles are the shortest routes between two places as we can connect any two places on the earth's surface by the curvature line of the great circle. And this curvature is the smallest possible route between those two places, because this curvature directly connects those places or points.
In what circumstances does great circle provide the most convenient route?
Great circle routes, which require constantly changing headings, are most useful beyond the equatorial regions and for distances greater than several hundred miles. Long-distance air traffic uses great circle routes routinely, saving time and fuel. Navigational radio signals also follow great circle paths.
How is the great circle useful in geography for class 9?
5. Great circles are used by navigators to find the shortest distance between any two points on the Earth's surface.
What is great circle track?
The great circle in question is the intersection of the spherical surface with the plane passing through the two points and the center of the earth. The great-circle path is different from the rhumb line unless the two points are both on the equator or both on the same meridian.
