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.
