10. Contaminated surface water can eventually enter groundwater and contaminate it. 11. Depending on the type of soil or rock, groundwater will flow at different rates. 12. Rain and snowmelt infiltrate (seep) into the ground to become groundwater. 1. False.
To understand how water moves in our world, attention must be directed to the hydrologic cycle. The hydrologic cycle is essentially a water continuum, representing the different paths through which water circulates and is transformed in the natural environment (Fig. 1). Being a cycle, it has no specific beginning or ending. Rather, liquid water from the Earth s surface, particularly the oceans, is evaporated into a gaseous form and enters the atmosphere as water vapor (clouds). The atmospheric moisture is eventually returned to the Earth s surface in the form of rain or snow.
