This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum surface area is "spherical shape".
Explain the terms 'Magnetic Dip' and 'Magnetic Declination' with the help of relevant diagrams.
Why we feel sky blue in color? The blue color of the sky is because of Rayleigh scattering. As light moves by the atmosphere, most of the longer wavelengths pass straight thr

Soft Ferromagnetic substances: Those substances that lose their magnetism are known as soft magnetic substances such as soft iron.
The force of attraction between the molecules of water is higher.
Because of surface tension, every thing in the universe wants to achieve stability,they do that by lowereing their energy.which in this case is the surface energy.a sphere offers lowest surface area yet a very large volume
