How deep is the ocean? - Excelled Montessori Plus

How deep is the ocean?

Researchers estimate that the ocean may be home to 700,000 marine species. 91 percent of ocean species have yet to be classified and more than 80 percent of our ocean is unmapped, unobserved, and unexplored.

“Watch the unending activity of the flowing stream or the growing tree. See the breakers of the ocean, the unceasing movements of the earth, the planets, the sun, and the stars. All creation is life, movement, work.”– Maria Montessori

Is the ocean water blue or clear?

What do you think? The ocean acts as a sunlight filter. 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.
