3 cards from this section. Quick, good the night before a test.
What causes ocean tides?
Think about celestial bodies.
Name one type of technology used to harness tidal energy.
They both deal with water movement.
What is tidal energy primarily caused by?
Think about which forces act on ocean waters.
True or False: Tidal energy generation is intermittent.
Consider how tides work over time.
A tidal barrage has a gate that allows water to flow at a rate of 700 cubic meters per second through a turbine. If the height difference between high and low tide is 4 meters, calculate the power generated assuming 100% efficiency. (Use g = 9.81 m/s²)
Use the formula Power = density * gravity * height * flow rate.
Argue for or against the design and construction of tidal energy systems in environmentally sensitive areas.
Think about ecological consequences and energy needs.
