Question 1: What percentage of the earth’s surface is covered by seas and oceans?
=> 75% of the earth’s surface is covered by the seas and oceans
Question 2: How do scientists now overcome the challenges of the depth?
=> By using modern devices
Question 3: What can submarines do to help scientists know about the undersea world?
=> They help them to investigate the sea bed and bring samples of the marine life back to the surface for further study.
Question 4: What can we learn from the satellite photos?
=> We can know a wide range of information including water temperature, depth and the undersea population.
Question 5: What are the three groups of marine plants and animals?
=> Some of them live on or depend on the bottom (like the starfish.)
Some are swimming animals (fishes, sharks that move independently of water current)
And others are tiny organisms
Question 6: What would happen if the sea biodiversity were not maintained?
=> The marine of life would be at stake (if the sea biodiversity were not maintained).
