Pumping large amounts of water from an aquifer may cause the

• water table to rise
• recharge zone to shrink
• wells in an area to run dry
• percolation of groundwater to stop

Thermal pollution has a harmful effect on aquatic environments because

• water has been circulated around power plant generators
• it increases the number of disease-causing organisms in aquatic environments
• it reduces the amount of dissolved oxygen in aquatic environments
• it decreases the nutrient levels in aquatic environments
