Consider the following statements:
1. Temperature of surface water is comparatively higher in the northern hemisphere than in the southern hemisphere.
2. The isotherms in the southern hemisphere are not regular and do not follow the latitudes while they (isotherms) are regular and follow the latitudes in the northern hemisphere.
