Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific name?N/A (Conceptual Infrastructure Design)
2. What is the habitat?Underwater at depths of 20-50 meters (66-164 ft)
3. How does the tunnel stay in place and not float up?It is kept steady by cables that pull it down to the seabed or by floating platforms above that hold it with tethers.
4. Why are they built between 20 to 50 meters deep?That depth keeps the tunnel safe from ships and storms but not so deep that the water pressure would need very strong, expensive walls.

Hydrostatic Thrust: The upward buoyant force exerted by a fluid, equal to the weight of the fluid displaced by an object.
Tensioned Tethers: Cables or ropes kept under strain to secure a floating structure and resist movement.
Seabed Foundation: The engineered base or anchoring system installed on the ocean floor to support submerged structures.
