Hydrologic Water Cycle-Definition and Various Steps involved in Hydrological Cycle
Water Cycle Process
Hydrologic Water Cycle process involves precipitation, evaporation, transpiration, infiltration and runoff.The air mass is said to be continental air mass when originated from land areas and maritime air mass when it originates from sea
The majority of earth water supply is contained in the oceans as saltwater and majority of fresh water is stored in iceberg or glaciers and the largest source of liquid freshwater is groundwater.
Different hydrological Water Cycle Steps
Evaporation
Water converted from liquid to gas
From surface waters(lakes, rivers, mostly oceans)
The energy need for the change of state is provided by the sun
Transpiration
Emission of water vapour from plants
Plants absorb water from the soil for photosynthesis process.
Water vapour released through stomata under leaves
Condensation
Water vapour turns into liquid water
As the vapour in air rises, it cools and turns back into liquid form in the sky
Precipitation
Water falling from the atmosphere
Vapour molecules collide and form liquid droplets
Fall as rain or snow
Infiltration
Water absorbs into subsurface or rocks
Simply we can say that percolation of water into the soil
Saturation occurs all the space between soil is filled with water
Groundwater
These infiltrated water will move down and reaches aquifers below the soil.The aquifer collects the water and they move into oceans though below the surface of the soil.There are two types of aquifers, confined and unconfined we will study later.
The surface of contact between two air mass and the surrounding atmosphere is called frontal surface and the intersection of the frontal surface with earth surface is called surface front.This is last hydrological cycle steps.Hope you got all.
What is cyclone?
A circular area of low atmospheric pressure in which the wind blows in the counterclockwise direction in the northern hemisphere and in the clockwise direction in the southern hemisphere is called cyclone.The centre of the cyclonic storm is called eye of the storm
What is anticyclone?
The high-pressure areas in which the wind blows in the clockwise direction in the northern hemisphere and anticlockwise in the southern hemisphere is called anticyclones.
