Question 99

Electricity is generated in hydroelectric power stations from water stored in reservoirs.

Statements A–F describe the main stages in the transfer of energy from the Sun to electrical energy in a hydroelectric power scheme. The statements are not in the correct order.

A: Water stored in a high-elevation reservoir flows down through pipes.
B: Water vapor rises, condenses into clouds, and falls as precipitation over high ground.
C: The generator produces electrical energy.
D: Solar radiation heats water in oceans and lakes, causing evaporation.
E: Flowing water turns the blades of a turbine.
F: The turbine turns a generator.

Complete the flowchart by identifying the missing letters in the sequence from top to bottom:

\boxed{\quad} \rightarrow \boxed{\text{B}} \rightarrow \boxed{\text{A}} \rightarrow \boxed{\quad} \rightarrow \boxed{\quad} \rightarrow \boxed{\quad}

[2]

State two disadvantages, apart from cost, of using hydroelectric dams to produce electrical energy.
