Question

examine the concept of the hydrologic cycle as an open system

Answer 1

Water is present on the surface of the earth in rivers,lakes,oceans,ponds and other water bodies.This water gets evaporated by the sun's heat and mixes with the atmosphere.Again, this vapour condenses and forms clouds and comes back to the earth's surface as rain or snow. This cyclical movement of water from the earth's surface and sub-surface to the atmosphere and vice versa is known as the hydrological cycle.
