What process moves water from the hydrosphere to the atmosphere? collection precipitation condensation evaporation

It would be evaporation because the sun evaporates the water, then the water turns into a cloud, then the wind moves it do the hydrosphere and the cloud gets so heavy that it cant hold any more water then it rains.

I'm not sure but i will try to find out

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
