1959 Water Cycle and Water Conservation: Johns Hopkins Science Review

The video discusses the increasing demands on eastern rivers, especially during summer when water is scarce. Trees and crops draw heavily on groundwater, causing streams to dry up. By autumn, the demand decreases, and the ground refills. In spring, excess water from rain and melting snow can cause floods. Farmers' irrigation needs further strain water resources, leaving little for community use, leading to shortages.

What happens to the water table during the summer months in the hills where the river rises?

• It remains stable throughout the year.

• It overflows due to excess water.

• It drops as trees draw on stored groundwater.

• It rises due to increased rainfall.

By which month is the ground typically saturated and ready for the next growing season?

• December

• February

• April

• June

What natural event occurs in spring due to the saturated ground?

• Drought

• Wildfire

• Flood

• Earthquake

How does irrigation affect river water levels during the summer?

• It causes the river to flood.

• It increases the river flow.

• It has no impact on river flow.

• It significantly reduces river flow.

What is a common consequence in communities during summer due to high water demand?

• Increased water supply

• Water shortages at kitchen taps

• More rainfall

• Lower electricity bills
