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.
Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earthâs rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents. Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep oceanâtaking nutrients, oxygen, and heat with them. Occasional events also trigger serious currents. Huge storms move water masses.
