Explanation:
1.Estuaries are often called the “nurseries of the sea,” because so many animals reproduce and spend the early part of their lives there. Salty seawater mixes with fresh water draining from the land to create habitats with unique conditions that are not found elsewhere.
3. Brackish water, also sometimes termed brack water, is water occurring in a natural environment having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers.
4. There are over 1500 naturally occurring salt-tolerant plants; trees (including mangroves), shrubs, grasses and herbs. These are collectively known as halophytes. A halophyte is a plant that completes its life cycle in a salty environment; many survive in seawater or even higher concentrations of salt.
6. The most iconic of all brackish water plants might be the Mangrove tree. Mangrove trees are a family of over 80 different species living in coastal intertidal zones. These amazing plants have developed their characteristic aerial root systems to cope with the changing tides where they live. Mangrove species live in tropical and sub-tropical regions, such as Florida, the Caribbean, South America, Africa, Southeast Asia, the South Pacific Islands, and Australia.
7. The four major types of estuaries classified by their geology are drowned river valley, bar-built, tectonic, and fjords. In geologic time, which is often measured on scales of hundreds of thousands to millions of years, estuaries are often fleeting features of the landscape.
8. Puerto Princesa Underground River Estuaries, Palawan, Philippines – The city has been acclaimed several times as the cleanest and greenest city in the Philippines.
Puerto Princesa is a nature lover's paradise.
9. Common rocky shore groups include mussels, barnacles, limpets, sea anemones, and predatory sea stars, each with a different ability to avoid predation or live outside of the water.
