| Parallels (Latitude) don’t intersect each other at any point. | All Meridians intersect at two places – North Pole and South pole. |
| In Parallels, we use the notations N and S for denoting directions. N – North S- South | In Meridians , we use the notations E and W for denoting the directions. E- East W- West |
| Each and every parallel is a full circle | Each and every meridian is a semi circle |
| Every Parallel is of different length | The length of each meridian is same |
| A distance of 19312.128 km is to be travelled to cross all the parallel | A distance of 38624.256 km is to be travelled to cross all the meridians. |
Q5. Answer the following question

1. Let we have to check the longitude of Point A.
2. See that the Point A is on the Right hand side i.e. The Point A is on East Side.
3. Check the Angles Now , The Point A is at 150 degree line.
4. The Point A is 150 degree East.
