Explanation:
Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral. Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.
The change in the ocean's temperature and salinity happens as we move further to the north and south of the equator. The reason for this is the icebergs and massive ice sheets. Icebergs after separating from the glaciers float in the oceans and start to melt. They provide cold and freshwater, lead to a change in the ocean. Antarctica and Greenland are the providers of the icebergs in the world.
