Water in liquid and solid form covers most of the 1._______of the Earth. By a complex process powered by 2._________ and the action of solar energy, an endless exchange of water, in 3. _________, liquid, and solid forms, takes place between the 4. __________, the oceans, and the crust. Water 5. ___________ in the air and in the oceans, as well as over and below the surface of landmasses. The 6. ____________of water in the planet is uneven. General patterns of circulation are present in the atmosphere, the oceans, and the landmasses, but regional features are very irregular and seemingly random in detail. Therefore, while causal relations underlie the overall process, it is believed that important elements of chance affect local 7. _______events.

Example:
| The motion of water can be described at many 0.________ scales. The fundamental concept of hydrology is the hydrological cycle– the global-scale, 1. _________ recirculatory process linking water in the atmosphere, on the continents, and in the oceans. We can think of this 2. _______ process in terms of reservoirs or compartments that store water (the oceans, atmosphere, etc.) and the 3.________ of water between them. Within the 4.________ compartments of the
5._____________ cycle, water can be stored in any one of these 6. ______ phases or stages: gas (vapor), liquid, or solid. For example, water in the atmosphere can exist as vapor (the 7. _________ of water vapor is expressed as 8. ________), in liquid (cloud droplets, rain drops), or in solid phase (ice crystals, snowflakes). Similarly, all three phases of water can be found on and below the land surface. Movement of water from one 9.__________ to another can occur in any of the three phases. For example, the movement of water between the oceans and atmosphere occurs in vapor phase 10._____________ from the ocean surface), liquid phase (rain onto the ocean surface), and solid phase (snowfall onto the ocean surface)
