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

1. How big is the Sea of Japan?Approximately 1,000,000 km² (386,000 sq mi)
2. How deep is the Sea of Japan?3,742 meters (12,277 ft)
3. What is the Sea of Japan known for?Less than 1% of water exchange
4. What is the average salinity?33-34 psu (practical salinity units)
5. What is the tidal range?Very small, typically less than 1 meter
6. Why does the Sea of Japan have a lower tidal range?The Sea of Japan has a lower tidal range because it is almost closed off from the open ocean. The narrow straits limit how much water can move in and out, so the tides are usually less than a meter.

Marginal Sea: A sea that is partially enclosed by land, characterized by limited exchange with the open ocean and distinct hydrological properties.
Thermohaline Circulation: Ocean currents driven by differences in temperature and salinity, influencing global water movement and nutrient distribution.
Biological Productivity: The rate at which biomass is generated by primary producers (like phytoplankton), indicating the health and capacity of an ecosystem.
Practical Salinity Units (psu): A standard measure of salinity, representing the total amount of dissolved salts in grams per kilogram of seawater.
