Water exists as a solid, liquid, and gas on Earth.
It is the only substance that naturally exists in all
three states within the relatively small range of
air temperatures and pressures found at the
earth's surface. How is this property of water
central to the planet's dynamics?
By changing states, water can evaporate
and transpirate into the atmosphere.
2. By changing states, water can condense
and travel from the atmosphere to Earth's
surface
3. By chimging states, water can influence
and shape Earth's surface. Precipitation
that falls can cause erosion and
weathering.
