Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface, or the surface of a celestial body.

  • It is an angular measurement, usually expressed in degrees.

Key Points

  1. The longitudes are imaginary semi-circular lines with the same radius.
  2. The distance between meridians decreases steadily polewards until it becomes zero at the pole.

Mistake Points

  1. The prime meridian and the International Date Line create a circle that divides the Earth into the eastern and western hemispheres. 

Hence, longitudes are the semi-circular lines. Which distance decreases steadily polewards and becomes Zero on the pole.

Consider the following statements about Latitude and Longitude. 1. As the earth is slightly flattened at the poles, the linear distance of a degree of latitude at the pole is a little shorter than that at the equator. 2. As the parallels of latitude become longer poleward, so the meridians of longitude, which converge at the poles, enclose a narrower space 3. The point at which the Equator and the Prime Meridian intersect is in the Gulf of Guinea in the Atlantic Ocean. Which of the statement/statements given above is/are correct.
Given below are two quantities named A and B. Based on the given information, you have to determine relation between the two quantities. You should use the given data and knowledge of Mathematics to choose between the possible answers. Quantity A: Number of hemispheres that can be formed by melting a sphere having volume equal to the volume of right circular cylinder whose diameteris 6 cm and height is 4 cm. Also, radius of hemisphere formed is half the radius of sphere from which the hemisphere is formed. Quantity B: Number of ice cream cones that can be made from a right circular cylinder shape ice cream container having radius 6 cm and height 5 cm. Ice cream cone to be made should have height 4 cm and slant height 5 cm and there should be a hemisphere made on top of the cone having radius equal to the radius of cone.

Gaurav cycles towards South-West for a distance of 6 m and stops there. Further, he moves towards East a distance of 10 m and from there he moves towards North-East a distance of 6 m. Next, he moves towards West a distance of 6 m. Now, he moves towards North-West a distance of 2 m. Next, he moves towards West a distance of 4 m and then towards South-West 6 m and stops at that point. Now, where is he from the starting point?
