89 lines in northern hemisphere and southern hemisphere respectively+ 1 equator totally 179

Janmenjaya Senapati answered Apr 26, 2020
Parallel of latitudes are horizontal circular imaginary lines on the earth surface so we can imagine infinite numbers of latitudes. But if we imagine the lines at an interval of 1 degree then total number will be 181.

All the latitudes are parallel with each other.Equator(imaginary horizontal circular line that divides earth in to two equal halves) is zero degree latitudes and is taken as reference.From the equator we have 90 parallels towards north pole and 90 parallels towards south pole (At poles we can imagine a point and not a circle) and both the poles are 90 degree latitudes.So in total we have 181 parallels (90 northwards+90 south wards+ equator).

Some people say 179 latitudes by not taking poles(as pole is not a circular line) so don't confused with that.....poles are also latitudes.

181 is the answer here

Jaya Gayathri answered May 04, 2020
Totally 181 parallels across the globe because 90 in northern hemisphere , 90 parallels in southern hemisphere and one in centre (i.e) the equator
therefore 90+90+1=181

Very simple question...
there are 90 parallel on northern hemisphere and 90on southern hemisphere and one equator..
total:90+90+1=181.

The equator is between of the earth. Correct answer is A because only 360 was divided by 2 after subtracted by 1. 181-1=180÷2=90.

Very simple mate .


There are 90 latitudes to the north of equator and 90 latitudes to the south of the equator. Counting the equator there are 90+90+1=181 latitudes.

90 parallels in northern hemisphere ,90 parallels in southern hemisphere and 1 is equator so equal to 181 parallels in globe

Shikha Shikha answered Jul 03, 2020
The count of whole-degree “lines” of latitude (the poles, the equator, and those in between) is indeed 181 . Of course that is because there are 360 degrees in a circle. Now the count of whole-degree lines of longitude is 360 …so why does latitude differ?

On a sphere (which our planet nominally is) all points are created equal so the difficulty is how to orient oneself. Fortunately the Earth spins (fairly stably) on an axis so we have its poles to use as a reference. Thus evenly-spaced lines of longitude were devised which pass through those poles: 360 of them…easy peasy.

That accounts for one dimension of the sphere’s two-dimensional surface, but what about the other one? One might manufacture two more “poles” equidistant from the real ones. But, boy, what a mess of grid lines that would make! A much better solution was to have evenly-spaced parallel circles which shrunk in size as they approached each pole: the lines of latitude. Now if one were to traverse a line of longitude all the way around the world one would cover 360 degrees of latitude. However that counts each (non-pole) latitude twice so the “proper” count is the aforementioned 181 .


But then, one may ask, why are there 360 degrees in a circle? Well, blame the Babylonians. There are two schools of thought as to exactly how that number arose.

180 answer is right

Rishita T answered May 31, 2018
There are 181 altitudes altogether. The latitude ; a circled shape imaginary line: drawn parallel to each other. They are equal numbers on both the northern and southern. Generally, both the last southern and northern circles can't be considered as real circles since they terminate as a point. However, it can be considered as an imaginary infinite circle. Thus 90 southern latitudes, an equator, 90 northern latitudes equal 181. Beside, there are only 179 real circled latitudes in total.

The total number of latitudes (the angular distance) is 90+90+1(Equator) = 181. The total number of parallels of latitude is 181–2(the poles are points) = 179.

There are total 181 parallels of latitudes.90 in northern hemisphere +90 in southern hemisphere+1equator.
we generally think that poles are the only points not the parallels but it is our misunderstanding because we assume this according to globe which is very small representation of earth but in actual ,if we see the earth ,these small points on globe which shows the poles are a vast flat area which is parallel to all other latitudes.

Sher Singh answered Jun 14, 2020
There are 181 lines of the parallels across the globe. since 90 lines in Nothern hemisphere, 90 lines in Southern hemisphere and 1 equator. that's why total number of parallels across the globe is ( 90+90+1)=181. but if 179 lines have been given in the option, in that condition, this is the correct answer because 1 northern and 1 southern pole not lines become in globe. that's reason total number of parallels across of the globe is ( 89+89+1)=179.

90 N latitudes and 90 south ones 0- equator
total 181
with north pole and south pole being points merely points
reduced to 179
so A is the answer.

181 parallels

Explanation: The Earth is divided by the Equator into two equal halves known as the Northern Hemisphere (with 90 parallels) and the Southern Hemisphere (with 90 parallels). These 180 parallels along with the Equator make a total of 181 parallels across the globe.

As per NCERT total no of parallels =179 excluding the Equator,
The two poles can be excluded as they are just points.

But the ans. can be 181 if we consider the Equator,
As 90 North latitude+90 South Latitude+1 Equator=181

In northern hemisphere, leaving equator (0 degree), there are 90 parallel lines each for one degree. Similarly 90 parallel lines are in southern hemisphere.
Now adding altogether including equator line, we get 181 lines.

Syed Sahadht Gillani answered Jun 22, 2020
The northern most latitude is 90N and the southern most is 90S. This makes the total number of latitudes 90+90+1 (including 0 degree - equator) = 181

The western most longitude is 180W and the eastern most longitude is 180E; incidentally, 180W and 180E are the same longitude. This is called the 180th meridian and also the international date line.

Therefore, the total number of longitudes is 180+180+1–1 (180 west longitudes, 180 east longitudes, -1 because 180E and 180W are the same longitude, +1 for 0degree longitude - the prime meridian) = 360
Therefore, the total number of latitudes are 181; and the total number of longitudes are 360.

Parallel lines then you are talking about latitude. because, longitudes are not parallel to each other, they shrink towards poles.
an9d no of total parallel lines is 181
90( from 1°N- 90°N) lines in northern hemisphere
90(from 1°S-90°S) lines in southern hemisphere
1( 0°)is equtorial line
so, they are total 181 in numbers.
90°N and 90°S is just like a point.
so, if we are talking about parallel , they will be 179 in numbers.

The answer is 181. We know that total degree of latitudes are 180° i.e 90° in the north and 90°in the south.
But the total number of parallel have been asked and the answer is 181.
90 parallel in the north and 90 parallels in the south and one parallels i.e equator in the middle.
So we say that there is 181 number of parallel and 180°of parallels.

Sapna Rani answered May 22, 2020
Parallel of latitude are horizontal circular imaginary lines on the earth surface so we can imagine infinite number of latitude. they are equal number on earth on both the northern and southern.
