Water?s Changes of State Water exists in all 3 states of matter and is made of hydrogen and oxygen atoms. In all 3 stages of matter, these molecules are in constant motion (higher temperature: more movement). Difference between 3 states is the arrangement of the water molecules. A. Ice, Liquid Water, and Water Vapor Ice is made of water molecules held together by mutual molecular attractions.They form a tight, orderly network and don?t move - they vibrate in a fixed position. When ice is heated, the molecules vibrate more, and when the rate of movement increases enough, the bonds between the molecules break, resulting in melting In the liquid state, the molecules are still tightly packed but move fast enough to slide past each other (this causes liquid water to be fluid)

Earth-Sun Relationships The Sun is the source from almost all of the Earth?s weather and climate. Earth intercepts 12000000000 (one two-billionth) of all the energy given off by the sun (this is several hundred thousand times the energy generation of the US). Solar energy isn?t evenly distributed; the amount of energy varies with latitude, time of day, and season. Unequal heating of Earth creates winds and ocean currents, which transport heat to balance energy inequalities; the consequences of these processes are called weather. If the Sun died, global winds and currents would stop; but if the Sun shines, the winds will blow and weather will exist. Variations in solar heating are caused by the motions of the Earth relative to the Sun and variations in the Earth?s land-sea surface.
