The rainfall pattern depends on-
(a)The underground water table
(b)The number of water bodies in an area
(c)The density pattern of the human population in an area
(d)Prevailing season in an area
Solution
The general water cycle illustrates that water evaporates and they form dense clouds. When these clouds get heavier they pour down like rain. This water collected from the rain flows down through slops and collects up in the nearest water bodies like- rivers, lakes, ponds, sometimes oceans, reservoirs, etc.
Complete answer:
The pattern of rainfall depends on the number of water bodies in an area since the region has more water bodies that evaporate more water and this evaporation increases the cycle of precipitation water and thus initiates the rainfall.
Precipitation process-
-As the water temperature increases in the seas or reservoirs due to sunshine, water evaporates and increases into the atmosphere.
-Water vapor is produced into a cloud accumulated in the atmosphere, climbing up to the mountains and higher places by the wind.
-Vapours are converged and converted into water droplets where the air temperature is lower than the dew point temperature in mountains and higher areas.
-By mixing soil and dust in the air, tiny water drops collide with each other when rising in the clouds, becoming bigger and heavier.
-When heavy drops of water with a size greater than 2 mm fall on the ground by gravity, water drops become raindrops.
-If the air temperature is below zero degrees Celsius, snowfalls.
Additional Information: The water cycle illustrates the constant flow of water within the atmosphere and the Earth. In the form of rain and snow, liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to Earth. Water (transportation) travels through the atmosphere in various phases.
So, the correct answer is ‘the number of water bodies in an area’.
Note: Moisture moving through three-dimensional zones of temperature and moisture contrasts known as weather fronts are the main cause of rain production. Global warming, including wetter conditions across eastern North America and drier conditions in the tropics, is also causing changes in the precipitation pattern globally.
