Thank you...And have a nice day.

Respuesta :

1. Drought period - in time periods where there is more precipitation there is more water availability, and when there's not there isn't.
Floods - when there are floods there is much more water available.
Population density - in places with more population there is a greater need for water supply, while in places where there is lesser people, the water supply can be smaller.
2. The land, air, and water are heated each day by the sunlight. The heat produced by the sun that hits the earth as the earth rotates is then part kept by the atmosphere that doesn't permeate all of that heating energy.
3. By evaporation. As the sun heats the ocean, there is evaporation. As the ocean moves around with its tides there is also loss of water to the air. Also by the waves and winds there is water that's lost to the air.
4. Part of that vapour will be reabsorbed by the ocean because it cools and precipitates into the ocean. Other part of it is taken with the wind to land or to upper spheres of the atmosphere.
 5. Part is reabsorbed but other part isn't. The other part is taken by the wind. As a gradient, there is less water in the air then in the ocean, keeping it above the ocean.
6. There is more water in the oceans then on the land. Water remains in the air on average about 9-10 days.
7. --------
8. An average American family uses about 300 gallons of water.
9. About 22%.
10. About 27%.

The answer can be explained as:

1. Water variability can be affected by drought periods, floods, and population density. For instance, an area with a higher population will have more need for water supply as compared to the region with little population.

2. The land, air, and water heat up by the light rays. The light rays are trapped by the atmosphere, which results in the rise of global temperature.

3. Oceans are large water bodies, which undergo evaporation. The oceans evaporated and result in water vapors, which are utilized in the water cycle.

4. The water vapor can evaporate, condense or precipitate depending on the environmental conditions.

5. The water vapors are carried away by the winds, which then follow the path of the hydrological cycle within the atmosphere, lithosphere, and biosphere.

6. The oceans are large water bodies, which are directly in contact with the air and light rays. The water vapor directly evaporates from the ocean surface and takes usually 9 to 10 days.

7. Freshwater can be obtained from the surface-water source, groundwater source, and reservoirs.

8. The average American family utilizes 300 gallons of water.

9. Approximately 22% of the water is used for washing and cleaning clothes.

10. About 27% of the water is used to flush and clean the toilets.
