Detailed explanation-1: -Water in different phases moves through the atmosphere (transportation). Liquid water flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater). Groundwater moves into plants (plant uptake) and evaporates from plants into the atmosphere (transpiration).

Detailed explanation-2: -The hydrologic–or water–cycle is the continuous movement of water between the earth and the atmosphere. Water reaches land as precipitation such as rain and snow. Then the water evaporates, condenses in the atmosphere to form clouds, and falls to the earth again as precipitation, continuing the cycle.

Detailed explanation-3: -So how can we understand this magical process called the water cycle? There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam.

Detailed explanation-4: -Chemical elements and water are constantly recycled in the ecosystem through biogeochemical cycles. During the water cycle, water enters the atmosphere by evaporation and transpiration, and water returns to land by precipitation.

Detailed explanation-5: -Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration.
