Which of the following is not correct about the great circle?
Answer Details
A great circle is a type of circle that can be formed on the Earth's surface. It is called "great" because it has the same radius as the Earth.
Let's go through each statement and determine which one is not correct:
1. The statement says that the Equator is a Great Circle among the latitudes. This statement is **correct**. The Equator is indeed a great circle because it is a circle that cuts the Earth in half, dividing it into the Northern Hemisphere and the Southern Hemisphere.
2. The statement says that the Greenwich Meridian and the International Date Line are the only lines of latitude forming a Great Circle. This statement is **not correct**. The Greenwich Meridian and the International Date Line are not lines of latitude; they are lines of longitude. A great circle can be formed by any line of latitude, not just the Greenwich Meridian and the International Date Line.
3. The statement says that the Great Circle divides the Earth into two equal spheres. This statement is **not correct**. The Great Circle does divide the Earth, but not into equal spheres. Instead, it divides the Earth into two hemispheres, which are halves of the Earth.
4. The statement says that the center of the Great Circle is also the center of the Earth. This statement is **not correct**. The center of a great circle does not necessarily coincide with the center of the Earth. The center of a great circle is simply the midpoint of the circle, which can be anywhere on the Earth's surface.
To summarize:
- Statement 1 is correct.
- Statement 2 is not correct.
- Statement 3 is not correct.
- Statement 4 is not correct.
Therefore, the statement that is not correct about the great circle is statement 2, which claims that the Greenwich Meridian and the International Date Line are the only lines of latitude forming a Great Circle.
