Which of the following statements correctly explains the regional imbalance of water supply and demand across the UK, resulting in areas of water surplus and water deficit?
The North and West of the UK have a water deficit due to high surface runoff rates on steep terrain, while the South and East have a water surplus due to extensive low-lying sandstone aquifers.
The South and East of the UK have a water surplus due to lower average evaporation rates, while the North and West have a water deficit because of high industrial consumption in major urban centers.
The North and West of the UK have a water surplus due to high relief rainfall and lower population density, while the South and East experience a water deficit due to lower rainfall and higher population density.
Both regions maintain a natural water balance, as high agricultural demand in the South-East is offset by low domestic consumption, meaning water transfer schemes are unnecessary.
