What does a lagoon look like?
Coastal lagoons form along coastal plains—flat or gently sloping landscapes. … The size and depth of coastal lagoons often depend on sea level.

How does the ocean refresh itself?
In the open seas water in the sunlit zone receives lots of sun and has a higher temperature than the water below. Under normal condition the process of “upwelling” brings cooler water from down below towards the top. … The supply of nutrient rich cold water to the sunlit zone is critical in maintaining healthy oceans.
Why is 85 of plant life found in the ocean?
The find is probably a result of climate change thinning the Arctic ice and allowing sunlight to promote its growth.

How deep in the ocean can plants grow?
Vegetation relies on photosynthesis for energy sunlight can’t penetrate the ocean depths so plants can’t grow in deeper waters. However shallow coastal waters are a different story. Many varieties of sea vegetation thrive to depths to about 600 feet (183 meters) in the so-called “euphotic zone.”
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter this leaves behind colors in the blue part of the light spectrum for us to see.
