Re-order Paragraphs
Arrange the sentences into the correct order.
Put the sentences in the correct order:
- Because the tides follow a fixed astronomical schedule, the electricity output of these turbines can be forecast years in advance.
- As the tide rises and falls, water rushes past the turbine blades and spins them, driving generators housed within the structure.
- To capture this energy, they began building underwater turbines in narrow channels where tidal currents flow fastest.
- Engineers realized that this reliable movement of water could be harnessed to generate electricity, unlike wind or sunlight, which fluctuate unpredictably.
- The gravitational pull of the moon and sun causes ocean water to rise and fall predictably twice a day along most coastlines.
