Tides and the web of life
What historical machines used the rising and falling tide to grind grain during the Middle Ages?
nic Early humans used the predictable rhythm of tides to trap fish and power early industrial mills.
nic Ocean Tides and the Moon
The Moon pulls the ocean high (pulls it high!) / Keeping coastal life alive (keep it alive!)
nic Modern tidal power stations capture the kinetic energy of moving water to generate renewable electricity.
What is the coastal area called that is exposed to air at low tide and underwater at high tide?
During which geological period did massive tides potentially help vertebrates transition from sea to land?
Moon power: Tidal energy is the only major source of renewable energy on Earth powered by the Moon's gravity instead of the Sun.
The area of a seashore between the high and low water marks. In Olympic National Park, these daily tidal cycles sustain diverse communities of sea stars and anemones.
