Answer: With my knowledge about the molecular structure of water which states that water is made up of two (2) molecules of hydrogen one (1) molecule of oxygen, ice forms on the top of a lake through a distinct means.
When an Ice forms,the hydrogen atom of one water molecule will then form a weak hydrogen bond with the top of the oxygen atoms of two (2) other of the water molecules.
Thereafter, lining up the water molecules in this designated pattern takes up more space than having them randomly in a jumbled manner just as in the case of water in liquid form.

Answer: The answer is sublimation
Explanation:
Sublimation is a process by which a solid substance changes to its gaseous or vapour state without passing through the liquid phase.
- Ice and snow are solid forms of water
- water vapor is the gaseous form of water
Thus, Sublimation is said to have occurred in the atmosphere
We can say they're the ISOTOPES of an element.
Isotopes of an element means the atoms of the same element has the same number of protons but different number of neutrons. They're still the same element because their number of proton is the same, which is like an ID card number, each element has a specific number of protons.
Each element has different amount of Isotopes. Some may have a lot, probably up to twenty, and some only have one stable isotope. For example, in hydrogen, there's the hydrogen atom with 0 neutrons, 1 neutron and 2 neutrons. They're the Isotopes of hydrogen.
Different isotopes of an element has a different atomic mass, as the number of neutron is different. Additionally, they also have different abundance in the environment. Maybe certain Isotopes can be found more in the earth.
