How does the understanding of the structure of the atom you see both unity and diversity in forms of matter?

Answer : The structure of atom shows unity in forming a particular molecule, different atoms of different or same elements combine to form a molecule. This shows the unity in formation of molecules from atoms. Like H and O atom combines to give water molecule.

Diversity is from the union of atoms which defines their states of matter. As in solids,liquid and gaseous forms; the atoms combine to form a molecule which may or may not belong from the same state of the elements. Like H is in gaseous form and O is also in gaseous form, but water is in liquid state.

So, it is clear that the structure of atoms helps in ifentifying both unity and diversity in forms of matter.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
