* It is polar. Water molecules have a positive end and a negative end, which means that they can attract and bind to other molecules. This allows water to break down the bonds between atoms in rocks and minerals.
* It is reactive. Water can react with other substances to form new compounds. This can lead to the formation of new minerals, or the dissolution of existing minerals.
* It is abundant. Water is the most abundant liquid on Earth, which means that it is always available to interact with rocks and minerals.
