## What Is A Great Circle In Geography?

A great circle is **the largest possible circle that can be drawn around a sphere**. … The Equator is another of the Earth’s great circles. If you were to cut into the Earth right on its Equator, you’d have two equal halves: the Northern and Southern Hemispheres. The Equator is the only east-west line that is a great circle.

## What is a great circle in simple words?

: a **circle formed on the surface of a sphere by** the intersection of a plane that passes through the center of the sphere specifically : such a circle on the surface of the earth an arc of which connecting two terrestrial points constitutes the shortest distance on the earth’s surface between them.

## What is great circle Why is it called so?

**Any circle that circumnavigates the Earth and passes through the centre of the Earth** is called a great circle. The lines that do not pass through the centre of the earth are the small circles. … Thus a great circle always splits the Earth into two halves, so that the Equator is a great circle.

## What is a great circle answer?

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 meant by a great circle route?

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 is great circle in geography class 9?

Answer: A great circle is **any circle that divides the earth into a circumference of two equal halves**.

## What forms a great circle?

A great circle is created by **any line that slices through the center of a sphere**. Great circles on Earth are roughly 40,000 kilometers (24,855 miles) all the way around. … The Equator is around 40,075 kilometers (24,901 miles) in circumference.

## Who is known as great circle?

**The Equator** is the only east-west line that is a great circle. All other parallels (lines of latitude) get smaller as you get near the poles.

## 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.

## How many great circles are there in a sphere?

**an infinite number of great circles**that can be drawn on any perfect sphere. The longitude lines on a globe all form great circles that pass through the same two points (the North Pole and the South Pole). The Equator is another great circle.

## What is the value of the great circle?

Thus, a great circle divides the globe into two equal halves. Since they must follow the circumference of the Earth to divide it, great circles are **about 40,000 kilometers (24,854 miles) in length** along meridians.

## What is a great circle Brainly?

Answer: A great circle is defined as **any circle drawn on a globe with a center that includes the center of the globe**. A great circle divides the globe into two equal halves.In addition, great circles represent the shortest distance between two points anywhere on the Earth’s surface.

## What is a great circle which of the parallels of latitude is a great circle?

**The Equator**is the longest circle of latitude and is the only circle of latitude which also is a great circle.

## What are great circles how are great circles useful?

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 and small circle?

A Great Circle is **a plane that passes through the center of the earth**. … The shortest distance between any two points on the earth’s surface is attained along the arc of a Great Circle. Small Circles are lines that do not pass through the center of the earth. All Parallels other than the Equator are Small Circles.

## How do you plot a great circle?

To plot a great circle track on a **Mercator chart the navigator joins his point of** departure and his point of arrival by a straight line drawn on a gnomonic chart, and then transfers a series of positions on this straight line—read off in latitude and longitude—to his Mercator chart.

## What is the great circle in geography class 6?

Great circle: The Equator is known as the great circle, as it is **the largest circle that can be drawn on the globe**. This is because the equatorial diameter of the Earth is the largest.

## What is a semi great circle?

A semi-great circle on S is **a semicircle consisting of half of a great circle on S**.

## What do you mean by great circle name a latitude which forms a great circle?

Answer: A great circle is a **latitude which passes through the center of the earth and divides the earth into two equal halves**. Equator is also known as great circle.

## Is also known as the great circle?

**an orthodrome**, of a sphere is the intersection of the sphere and a plane that passes through the center point of the sphere. A great circle is the largest circle that can be drawn on any given sphere. … These great circles are the geodesics of the sphere.

## Is a great circle infinite?

A line is the shortest path between two points. … A straight line is infinite. 3. **A great circle is finite and returns to its original starting point**.

## Is Greenwich Meridian a great circle?

**all the lines running top to bottom (longitude) are great circles**. … The Greenwich Meridian goes through Greenwich and also the North and South Poles and any line that goes through both the North and South Poles must be a great circle, because the Poles are opposite each other.

## Which of the following is true about great circle?

(1) Great Circle is **an imaginary circle which divides the Earth into two equal hemispheres**. (2) Equator is the only Great Circle, which can be drawn on the Earth’s surface. (3) An arc of a Great Circle on the surface of the Earth marks the shortest distance between two points on the Earth.

## What is the great circle area?

A great circle is a circle that has the same center and radius as its sphere. … The great circle (with area **πr ^{2}**, obv) covers about a fourth of the sphere. Actually, it covers exactly a fourth of the sphere. That means our surface area for the entire sphere is four times the area of the great circle.

## Why are great circles Geodesics?

**because planes travel along the shortest route in a 3-dimensional space**. This route is called a geodesic or great circle route. They are common in navigation, sailing and aviation.

## How do you find a great circle?

…

**What is the Great Circle Formula?**

- r = Radius of the earth.
- a, b= Latitude.
- x, y = Longitude.

## What is the latitude of Tropic of Capricorn?

23.4394 degrees

The Tropic of Capricorn lies at 23d 26′ 22″ (23.4394 degrees) south of the Equator and marks the most southerly latitude at which the sun can appear directly overhead at noon. This event occurs at the December solstice, when the southern hemisphere is tilted towards the sun to its maximum extent.

## How will you define equator in your own words?

An equator is **an imaginary line around the middle of a planet or other celestial body**. … It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The Earth is widest at its Equator.

## Why are great circles 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 not true about great circles and great circle routes?

Shape is **relatively accurate**. Straight lines drawn on them , great circle routes for distances are not great. … Run in a north to south direction, but measure distance east and west of the prime meridian.
