Explanation:

1. A large body of standing freshwater is a lake. Lakes hold still - water and are common freshwater features.
2. The aphotic zone is the deeper part of the ocean where sunlight does not penetrate, making photosynthesis impossible. Lack of light restricts photosynthetic activity.
3. A partially enclosed coastal body of water where freshwater from rivers and streams meets and mixes with saltwater from the ocean is an estuary. Estuaries are unique mixing - zones.
4. Coral reefs are located predominantly in shallow, warm tropical waters, and are among the most diverse and productive on Earth, supporting an immense variety of marine species. They are known for high biodiversity.
5. Wetlands are transitional areas between aquatic and terrestrial environments, characterized by saturated soils or standing water for at least part of the year. They have unique hydrological and soil conditions.
6. The area along coastlines that is exposed to air at low tide and submerged at high tide is the intertidal zone. It experiences regular tidal changes.
7. The photic zone is the uppermost layer of water in the ocean, receiving enough sunlight to support photosynthesis and teeming with life. Sunlight availability enables photosynthesis.
8. Flowing bodies of freshwater that move continuously in a single direction are rivers or streams. They have a unidirectional water - flow.
9. The open ocean, also known as the pelagic zone, is the vast, deep body of saltwater that covers the majority of Earth's surface. It is a large and deep marine environment.
10. The measure of the amount of dissolved salts in water is salinity. It is an important water - quality parameter.
11. One of the main threats to the health of marine ecosystems is urban development. Urban activities can lead to pollution and habitat destruction.
